I'm trying to figure out what a Java applet's Class file is doing under the hood. Opening it up w/ Notepad or Textpad just shows a bunch of gobbley-gook.
Any way to wrangle it back into a somewhat readable format so's I can try to figure out what it's doing?

You need to escape the backslashes within the mapping. You can also include the substitution string within the mapping.

"const" is a keyword, but you can't use it.
int const = 1; // "not a statement"
const int i = 1; // "illegal start of expression"
I guess the compiler writers thought it might be used in the future and they'd better keep it reserved. |
