Tutorial :Java bytecode equivalents for ilasm / ildasm


For CIL / MSIL, I can write the code in a text editor and compile / decompile with ilasm / ildasm.

I can use Reflector to see the CIL generated by a .NET class.

In the Java world, javap -c shows the disassembled byte code.

How do I compile Java bytecode? (i.e. the Java equivalent of ilasm / ildasm).

Is there an IDE that supports Java bytecode?

Does the IDE support debugging i.e. single stepping / breakpoints etc.?


Bytecode Outline plugin for Eclipse

to play with bytecode you can use ASM or BCEL

Take a look at org.apache.bcel.util.BCELifier, it takes a given class and converts it to a BCEL program (in Java, of course). It will show you how certain code is generated using BCEL.




It's an assembler for Java bytecode. While an above poster pointed out that hand-coding Java bytecode may not be very useful, Jasmin has been used as a backend for compilers targeting the JVM as a runtime. Thus, your compiler can output Jasmin assembler instructions and then Jasmin converts them into Java classes.
