i hava one doubt about how to convert
the .class files into .java files without using any tool ?.In this case, without
having the original java file i'm trying to convert it into .class file into
that java file(decompiler)

For example,If u take apt.class, u have to
convert it into apt.java file. But u don't have the actual apt.java file . You
have to get that file from the available apt.class file
