*

  • The {@code Throwable} class is the superclass of all errors and
  • exceptions in the Java language. Only objects that are instances of this
  • class (or one of its subclasses) are thrown by the Java Virtual Machine or
  • can be thrown by the Java {@code throw} statement. Similarly, only
  • this class or one of its subclasses can be the argument type in a
  • {@code catch} clause. *
  • For the purposes of compile-time checking of exceptions, {@code
  • Throwable} and any subclass of {@code Throwable} that is not also a
  • subclass of either {@link RuntimeException} or {@link Error} are
  • regarded as checked exceptions. *
  • <p>Instances of two subclasses, {@link java.lang.Error} and
  • {@link java.lang.Exception}, are conventionally used to indicate
  • that exceptional situations have occurred. Typically, these instances
  • are freshly created in the context of the exceptional situation so
  • as to include relevant information (such as stack trace data). *
  • <p>A throwable contains a snapshot of the execution stack of its
  • thread at the time it was created. It can also contain a message
  • string that gives more information about the error. Over time, a
  • throwable can {@linkplain Throwable#addSuppressed suppress} other
  • throwables from being propagated. Finally, the throwable can also
  • contain a <i>cause</i>: another throwable that caused this
  • throwable to be constructed. The recording of this causal information
  • is referred to as the <i>chained exception</i> facility, as the
  • cause can, itself, have a cause, and so on, leading to a "chain" of
  • exceptions, each caused by another. *
  • <p>One reason that a throwable may have a cause is that the class that
  • throws it is built atop a lower layered abstraction, and an operation on
  • the upper layer fails due to a failure in the lower layer. It would be bad
  • design to let the throwable thrown by the lower layer propagate outward, as
  • it is generally unrelated to the abstraction provided by the upper layer.
  • Further, doing so would tie the API of the upper layer to the details of
  • its implementation, assuming the lower layer's exception was a checked
  • exception. Throwing a "wrapped exception" (i.e., an exception containing a
  • cause) allows the upper layer to communicate the details of the failure to
  • its caller without incurring either of these shortcomings. It preserves
  • the flexibility to change the implementation of the upper layer without
  • changing its API (in particular, the set of exceptions thrown by its
  • methods). *
  • <p>A second reason that a throwable may have a cause is that the method
  • that throws it must conform to a general-purpose interface that does not
  • permit the method to throw the cause directly. For example, suppose
  • a persistent collection conforms to the {@link java.util.Collection
  • Collection} interface, and that its persistence is implemented atop
  • {@code java.io}. Suppose the internals of the {@code add} method
  • can throw an {@link java.io.IOException IOException}. The implementation
  • can communicate the details of the {@code IOException} to its caller
  • while conforming to the {@code Collection} interface by wrapping the
  • {@code IOException} in an appropriate unchecked exception. (The
  • specification for the persistent collection should indicate that it is
  • capable of throwing such exceptions.) *
  • <p>A cause can be associated with a throwable in two ways: via a
  • constructor that takes the cause as an argument, or via the
  • {@link #initCause(Throwable)} method. New throwable classes that
  • wish to allow causes to be associated with them should provide constructors
  • that take a cause and delegate (perhaps indirectly) to one of the
  • {@code Throwable} constructors that takes a cause. *
  • Because the {@code initCause} method is public, it allows a cause to be
  • associated with any throwable, even a "legacy throwable" whose
  • implementation predates the addition of the exception chaining mechanism to
  • {@code Throwable}. *
  • <p>By convention, class {@code Throwable} and its subclasses have two
  • constructors, one that takes no arguments and one that takes a
  • {@code String} argument that can be used to produce a detail message.
  • Further, those subclasses that might likely have a cause associated with
  • them should have two more constructors, one that takes a
  • {@code Throwable} (the cause), and one that takes a
  • {@code String} (the detail message) and a {@code Throwable} (the
  • cause). *

  • @since 1.0

func NewThrowable 

func NewThrowable() *ThrowableObject

*

  • Constructs a new throwable with {@code null} as its detail message.
  • The cause is not initialized, and may subsequently be initialized by a
  • call to {@link #initCause}. *
  • <p>The {@link #fillInStackTrace()} method is called to initialize
  • the stack trace data in the newly created throwable.

func NewThrowable1 

func NewThrowable1(message string) *ThrowableObject

*

  • Constructs a new throwable with the specified detail message. The
  • cause is not initialized, and may subsequently be initialized by
  • a call to {@link #initCause}. *
  • <p>The {@link #fillInStackTrace()} method is called to initialize
  • the stack trace data in the newly created throwable. *
  • @param message the detail message. The detail message is saved for
  • later retrieval by the {@link #getMessage()} method.

func NewThrowable2 

func NewThrowable2(message string, cause Throwable) *ThrowableObject

*

  • Constructs a new throwable with the specified detail message and
  • cause. <p>Note that the detail message associated with
  • {@code cause} is <i>not</i> automatically incorporated in
  • this throwable's detail message. *
  • <p>The {@link #fillInStackTrace()} method is called to initialize
  • the stack trace data in the newly created throwable. *
  • @param message the detail message (which is saved for later retrieval
  • by the {@link #getMessage()} method).
  • @param cause the cause (which is saved for later retrieval by the
  • {@link #getCause()} method). (A {@code null} value is
  • permitted, and indicates that the cause is nonexistent or
  • unknown.)
  • @since 1.4

func NewThrowable4 

func NewThrowable4(message string, cause Throwable, enableSuppression, writableStackTrace bool) *ThrowableObject

*

  • Constructs a new throwable with the specified detail message,
  • cause, {@linkplain #addSuppressed suppression} enabled or
  • disabled, and writable stack trace enabled or disabled. If
  • suppression is disabled, {@link #getSuppressed} for this object
  • will return a zero-length array and calls to {@link
  • #addSuppressed} that would otherwise append an exception to the
  • suppressed list will have no effect. If the writable stack
  • trace is false, this constructor will not call {@link
  • #fillInStackTrace()}, a {@code null} will be written to the
  • {@code stackTrace} field, and subsequent calls to {@code
  • fillInStackTrace} and {@link
  • #setStackTrace(StackTraceElement[])} will not set the stack
  • trace. If the writable stack trace is false, {@link
  • #getStackTrace} will return a zero length array. *
  • <p>Note that the other constructors of {@code Throwable} treat
  • suppression as being enabled and the stack trace as being
  • writable. Subclasses of {@code Throwable} should document any
  • conditions under which suppression is disabled and document
  • conditions under which the stack trace is not writable.
  • Disabling of suppression should only occur in exceptional
  • circumstances where special requirements exist, such as a
  • virtual machine reusing exception objects under low-memory
  • situations. Circumstances where a given exception object is
  • repeatedly caught and rethrown, such as to implement control
  • flow between two sub-systems, is another situation where
  • immutable throwable objects would be appropriate. *
  • @param message the detail message.
  • @param cause the cause. (A {@code null} value is permitted,
  • and indicates that the cause is nonexistent or unknown.)
  • @param enableSuppression whether or not suppression is enabled or disabled
  • @param writableStackTrace whether or not the stack trace should be
  • writable *
  • @see OutOfMemoryError
  • @see NullPointerException
  • @see ArithmeticException
  • @since 1.7

func (*ThrowableObject) AddSuppressed 

func (t *ThrowableObject) AddSuppressed(exception Throwable)

*

  • Appends the specified exception to the exceptions that were
  • suppressed in order to deliver this exception. This method is
  • thread-safe and typically called (automatically and implicitly)
  • by the {@code try}-with-resources statement. *
  • <p>The suppression behavior is enabled <em>unless</em> disabled
  • {@linkplain #Throwable(String, Throwable, boolean, boolean) via
  • a constructor}. When suppression is disabled, this method does
  • nothing other than to validate its argument. *
  • <p>Note that when one exception {@linkplain
  • #initCause(Throwable) causes} another exception, the first
  • exception is usually caught and then the second exception is
  • thrown in response. In other words, there is a causal
  • connection between the two exceptions. *
  • In contrast, there are situations where two independent
  • exceptions can be thrown in sibling code blocks, in particular
  • in the {@code try} block of a {@code try}-with-resources
  • statement and the compiler-generated {@code finally} block
  • which closes the resource. *
  • In these situations, only one of the thrown exceptions can be
  • propagated. In the {@code try}-with-resources statement, when
  • there are two such exceptions, the exception originating from
  • the {@code try} block is propagated and the exception from the
  • {@code finally} block is added to the list of exceptions
  • suppressed by the exception from the {@code try} block. As an
  • exception unwinds the stack, it can accumulate multiple
  • suppressed exceptions. *
  • <p>An exception may have suppressed exceptions while also being
  • caused by another exception. Whether or not an exception has a
  • cause is semantically known at the time of its creation, unlike
  • whether or not an exception will suppress other exceptions
  • which is typically only determined after an exception is
  • thrown. *
  • <p>Note that programmer written code is also able to take
  • advantage of calling this method in situations where there are
  • multiple sibling exceptions and only one can be propagated. *
  • @param exception the exception to be added to the list of
  • suppressed exceptions
  • @throws IllegalArgumentException if {@code exception} is this
  • throwable; a throwable cannot suppress itself.
  • @throws NullPointerException if {@code exception} is {@code null}
  • @since 1.7

func (*ThrowableObject) Error 

func (t *ThrowableObject) Error() string

func (*ThrowableObject) GetCause 

func (t *ThrowableObject) GetCause() Throwable

*

  • Returns the cause of this throwable or {@code null} if the
  • cause is nonexistent or unknown. (The cause is the throwable that
  • caused this throwable to get thrown.) *
  • <p>This implementation returns the cause that was supplied via one of
  • the constructors requiring a {@code Throwable}, or that was set after
  • creation with the {@link #initCause(Throwable)} method. While it is
  • typically unnecessary to override this method, a subclass can override
  • it to return a cause set by some other means. This is appropriate for
  • a "legacy chained throwable" that predates the addition of chained
  • exceptions to {@code Throwable}. Note that it is <i>not</i>
  • necessary to override any of the {@code PrintStackTrace} methods,
  • all of which invoke the {@code getCause} method to determine the
  • cause of a throwable. *
  • @return the cause of this throwable or {@code null} if the
  • cause is nonexistent or unknown.
  • @since 1.4

func (*ThrowableObject) GetLocalizedMessage 

func (t *ThrowableObject) GetLocalizedMessage() string

*

  • Creates a localized description of this throwable.
  • Subclasses may override this method in order to produce a
  • locale-specific message. For subclasses that do not override this
  • method, the default implementation returns the same result as
  • {@code getMessage()}. *
  • @return The localized description of this throwable.
  • @since 1.1

func (*ThrowableObject) GetMessage 

func (t *ThrowableObject) GetMessage() string

*

  • Returns the detail message string of this throwable. *
  • @return the detail message string of this {@code Throwable} instance
  • (which may be {@code null}).

func (*ThrowableObject) GetOurStackTrace 

func (t *ThrowableObject) GetOurStackTrace() []byte

func (*ThrowableObject) GetStackTrace 

func (t *ThrowableObject) GetStackTrace() []byte

*

  • Provides programmatic access to the stack trace information printed by
  • {@link #printStackTrace()}. Returns an array of stack trace elements,
  • each representing one stack frame. The zeroth element of the array
  • (assuming the array's length is non-zero) represents the top of the
  • stack, which is the last method invocation in the sequence. Typically,
  • this is the point at which this throwable was created and thrown.
  • The last element of the array (assuming the array's length is non-zero)
  • represents the bottom of the stack, which is the first method invocation
  • in the sequence. *
  • <p>Some virtual machines may, under some circumstances, omit one
  • or more stack frames from the stack trace. In the extreme case,
  • a virtual machine that has no stack trace information concerning
  • this throwable is permitted to return a zero-length array from this
  • method. Generally speaking, the array returned by this method will
  • contain one element for every frame that would be printed by
  • {@code printStackTrace}. Writes to the returned array do not
  • affect future calls to this method. *
  • @return an array of stack trace elements representing the stack trace
  • pertaining to this throwable.
  • @since 1.4

func (*ThrowableObject) GetSuppressed 

func (t *ThrowableObject) GetSuppressed() []Throwable

*

  • Returns an array containing all of the exceptions that were
  • suppressed, typically by the {@code try}-with-resources
  • statement, in order to deliver this exception. *
  • If no exceptions were suppressed or {@linkplain
  • #Throwable(String, Throwable, boolean, boolean) suppression is
  • disabled}, an empty array is returned. This method is
  • thread-safe. Writes to the returned array do not affect future
  • calls to this method. *
  • @return an array containing all of the exceptions that were
  • suppressed to deliver this exception.
  • @since 1.7

func (*ThrowableObject) InitCause 

func (t *ThrowableObject) InitCause(cause Throwable) Throwable

*

  • Initializes the <i>cause</i> of this throwable to the specified value.
  • (The cause is the throwable that caused this throwable to get thrown.) *
  • <p>This method can be called at most once. It is generally called from
  • within the constructor, or immediately after creating the
  • throwable. If this throwable was created
  • with {@link #Throwable(Throwable)} or
  • {@link #Throwable(String,Throwable)}, this method cannot be called
  • even once. *
  • <p>An example of using this method on a legacy throwable type
  • without other support for setting the cause is: *
  • <pre>
  • try {
  • lowLevelOp();
  • } catch (LowLevelException le) {
  • throw (HighLevelException)
  • new HighLevelException().initCause(le); // Legacy constructor
  • }
  • </pre> *
  • @param cause the cause (which is saved for later retrieval by the
  • {@link #getCause()} method). (A {@code null} value is
  • permitted, and indicates that the cause is nonexistent or
  • unknown.)
  • @return a reference to this {@code Throwable} instance.
  • @throws IllegalArgumentException if {@code cause} is this
  • throwable. (A throwable cannot be its own cause.)
  • @throws IllegalStateException if this throwable was
  • created with {@link #Throwable(Throwable)} or
  • {@link #Throwable(String,Throwable)}, or this method has already
  • been called on this throwable.
  • @since 1.4

func (*ThrowableObject) PrintEnclosedStackTrace 

func (t *ThrowableObject) PrintEnclosedStackTrace(writer io.Writer, enclosingTrace []byte,
	caption string, prefix string, dejaVu map[Throwable]struct{})

*

  • Print our stack trace as an enclosed exception for the specified
  • stack trace.

func (*ThrowableObject) PrintStackTrace 

func (t *ThrowableObject) PrintStackTrace()

*

  • Prints this throwable and its backtrace to the
  • standard error stream. This method prints a stack trace for this
  • {@code Throwable} object on the error output stream that is
  • the value of the field {@code System.err}. The first line of
  • output contains the result of the {@link #toString()} method for
  • this object. Remaining lines represent data previously recorded by
  • the method {@link #fillInStackTrace()}. The format of this
  • information depends on the implementation, but the following
  • example may be regarded as typical:
  • <blockquote><pre>
  • java.lang.NullPointerException
  • at MyClass.mash(MyClass.java:9)
  • at MyClass.crunch(MyClass.java:6)
  • at MyClass.main(MyClass.java:3)
  • </pre></blockquote>
  • This example was produced by running the program:
  • <pre>
  • class MyClass {
  • public static void main(String[] args) {
  • crunch(null);
  • }
  • static void crunch(int[] a) {
  • mash(a);
  • }
  • static void mash(int[] b) {
  • System.out.println(b[0]);
  • }
  • }
  • </pre>
  • The backtrace for a throwable with an initialized, non-null cause
  • should generally include the backtrace for the cause. The format
  • of this information depends on the implementation, but the following
  • example may be regarded as typical:
  • <pre>
  • HighLevelException: MidLevelException: LowLevelException
  • at Junk.a(Junk.java:13)
  • at Junk.main(Junk.java:4)
  • Caused by: MidLevelException: LowLevelException
  • at Junk.c(Junk.java:23)
  • at Junk.b(Junk.java:17)
  • at Junk.a(Junk.java:11)
  • ... 1 more
  • Caused by: LowLevelException
  • at Junk.e(Junk.java:30)
  • at Junk.d(Junk.java:27)
  • at Junk.c(Junk.java:21)
  • ... 3 more
  • </pre>
  • Note the presence of lines containing the characters {@code "..."}.
  • These lines indicate that the remainder of the stack trace for this
  • exception matches the indicated number of frames from the bottom of the
  • stack trace of the exception that was caused by this exception (the
  • "enclosing" exception). This shorthand can greatly reduce the length
  • of the output in the common case where a wrapped exception is thrown
  • from same method as the "causative exception" is caught. The above
  • example was produced by running the program:
  • <pre>
  • public class Junk {
  • public static void main(String args[]) {
  • try {
  • a();
  • } catch(HighLevelException e) {
  • e.printStackTrace();
  • }
  • }
  • static void a() throws HighLevelException {
  • try {
  • b();
  • } catch(MidLevelException e) {
  • throw new HighLevelException(e);
  • }
  • }
  • static void b() throws MidLevelException {
  • c();
  • }
  • static void c() throws MidLevelException {
  • try {
  • d();
  • } catch(LowLevelException e) {
  • throw new MidLevelException(e);
  • }
  • }
  • static void d() throws LowLevelException {
  • e();
  • }
  • static void e() throws LowLevelException {
  • throw new LowLevelException();
  • }
  • } *
  • class HighLevelException extends Exception {
  • HighLevelException(Throwable cause) { super(cause); }
  • } *
  • class MidLevelException extends Exception {
  • MidLevelException(Throwable cause) { super(cause); }
  • } *
  • class LowLevelException extends Exception {
  • }
  • </pre>
  • As of release 7, the platform supports the notion of
  • <i>suppressed exceptions</i> (in conjunction with the {@code
  • try}-with-resources statement). Any exceptions that were
  • suppressed in order to deliver an exception are printed out
  • beneath the stack trace. The format of this information
  • depends on the implementation, but the following example may be
  • regarded as typical: *
  • <pre>
  • Exception in thread "main" java.lang.Exception: Something happened
  • at Foo.bar(Foo.java:10)
  • at Foo.main(Foo.java:5)
  • Suppressed: Resource$CloseFailException: Resource ID = 0
  • at Resource.close(Resource.java:26)
  • at Foo.bar(Foo.java:9)
  • ... 1 more
  • </pre>
  • Note that the "... n more" notation is used on suppressed exceptions
  • just at it is used on causes. Unlike causes, suppressed exceptions are
  • indented beyond their "containing exceptions." *
  • <p>An exception can have both a cause and one or more suppressed
  • exceptions:
  • <pre>
  • Exception in thread "main" java.lang.Exception: Main block
  • at Foo3.main(Foo3.java:7)
  • Suppressed: Resource$CloseFailException: Resource ID = 2
  • at Resource.close(Resource.java:26)
  • at Foo3.main(Foo3.java:5)
  • Suppressed: Resource$CloseFailException: Resource ID = 1
  • at Resource.close(Resource.java:26)
  • at Foo3.main(Foo3.java:5)
  • Caused by: java.lang.Exception: I did it
  • at Foo3.main(Foo3.java:8)
  • </pre>
  • Likewise, a suppressed exception can have a cause:
  • <pre>
  • Exception in thread "main" java.lang.Exception: Main block
  • at Foo4.main(Foo4.java:6)
  • Suppressed: Resource2$CloseFailException: Resource ID = 1
  • at Resource2.close(Resource2.java:20)
  • at Foo4.main(Foo4.java:5)
  • Caused by: java.lang.Exception: Rats, you caught me
  • at Resource2$CloseFailException.&lt;init&gt;(Resource2.java:45)
  • ... 2 more
  • </pre>
