Using expression, statement etc.

[Julius Bezaras]

Hi, I'm new and would like to get some help.

I'm  trying to make a program that reads text file with java code, finds if statement and changes if condition (ex. if (i > 3) -> if (i < 3)) or something like that.

I've been at it all day just can't get it to work. Can someone show me how or give an advice how to do that bloody thing? 

P.S. And yes I have read https://code.google.com/p/javaparser/wiki/UsingThisParser, didn't help...
