There is no way to convert compiled code into source code. The brain is the best tool to do this job.

yeah, but it wont convert compiled code into 'source' code. Will show ASM, and the only tool to convert ASM into source is your brain, so...

For Java you can use "DJ Java Decompiler" download from internet and get a working serial

, you can decompile Java (and other languages as C#, VB.NET, C++ CLR) because aren't native executables.

From native apps compiled in Delphi and C++ you can dissasemble and understand ASM

so the most smart way to approch is to learn assembly and then rewrite the output ?
However optimizing by the compiler will remove comments and variable names, and classes will be different ?

Hi,

Try to learn C to the max. Then begging to experiment with embedded
projects - compile them, modify them, compile again....

Every time you compile, put the output file (use a object file that IDA
will recognize) in IDA. Watch and learn, till you get the feel of the ASM
flow.

After few years, reading ASM will be to you as reading C code, the same way
an old Morse Code operator hears the beeps as words and sentences.

If you know how the C complier works, you don't need variable names and
comments.
