Hi Viral,

I found that there are two type of statements that involve in branching – flow control instructions and the switch instructions (table switch and lookup switch).

I am able to decompile most of the bytecode except in detecting loops. What are the rules to detect loops in the code attribute instructions for a method? I tried to identify by patterns but gave up. Every compiler can generate it’s code in different ways.

Any pointers would also be very helpful… Also, is it very math intensive?

Thanks,
Keshavan

[...] Decompiler knows about the structure of a Java class and parse it to generated Java source [...]

Hi Anupriya,
For decompiling any Java Class, you can use lots of Decompilers available freely.
One such decompiler is JAD http://www.kpdus.com/jad.html

Hope this will solve your query.

I really liked your simple way of explaining the whole ClassFile structure! I’ve been reading SUN’s specification throu Tim and Frank book titled “The java virtual machine specification” for two days and honestly, I kept flipping back and forth to remember what’s the connection. Here the connection is really obvious ! Thanks
