The

...

Jasm format.

The JASM format is well suited to represent semantics of byte-code instructions within the method of a class.  The JASM format uses mnemonics descriptions for encoding instructions - the same mnemonic language described in Chapter 6 of the  Java VM specification.  The JASM format also uses a Java-like syntax for class/method/field descriptions, access_flag mask values (that are decoded into "public", "protected", etc modifiers), and indexes into the constant pool (that can optionally be replaced with the values).

In this listing, you can see how the syntax is a mixture of Java declarations (for describing member signatures), Strings (encoded in the format that constants are represented in the constant pool), and Java instruction mnemonics.  This type of format lends itself well to create class files to test incorrect sequences of instructions.

The

...

Jcod format.

The JCOD format is well suited to represent the structure of a class file (more so than instruction sequences).
