No Java lesson for today, as I'm a bit busy (lazy :P). Instead I'll show you some cool tricks with Jad.
Sometimes when you try to decompile a class you see an error message saying "Class file version mismatch". But you can still go on and force Jad to decompile it using the -debug option:
jad -debug Test.classAnother common case is when there are many classes (like in qtj2) and you want to do a batch decompilation. The wildcard character can help a bit:
jad *.classBut this one is much cooler:
jad -r quangntenemy**/*.class
