Chapter01

In Chapter01 I defined cmd.go to parse the command line with the help of flag and os package in go detailed code is in ch01

• flag package can help us to parse the command line options

• os package is used to deal with the arguments passed into our programm

Chapter02

In Chapter02 I defined several types of class file: *.class, *.jar, .zip, / with Composite pattern

• entry_composite: define a list of path which contains class files

• entry_dir: store the absolute path

• entry_wildcard: treat the /* case

• entry_zip: deal with the jar and zip file

In classpath.go I get initilize

• bootClasspath Entry

• extClasspath Entry

• userClasspath Entry by passing the -Xjre option and -cp Option. To be specific, -Xjre option points to where the bootstrap and extension class locate and -cp Option points to where the user defined class locat (by default it is ".")
