Classfile Reader & Writer

这个包使得读写java class文件变得很容易。它可以很容易得把class文件的内容显示给用户

InputStream is = new FileInputStream("Foo.class");
OutputStream os = new FileOutputStream("FooCopy.class");
ClassInfo classInfo = new ClassInfo();
new ClassFileReader().read(is, classInfo);
classInfo.setName("FooCopy");  // Java requires the class name to match the file name
new ClassFileWriter().write(classInfo, os);
is.close();os.close();
