Well, I've been dealing with a big problem. I have two classes which has same class name and package structure they are present in two different jars for sure.
When I call a method of one class say for example setName.
I get an exception saying noSuchMethod; what can be the possible soluntion in this regard.
As classes are in jars I cant make any changes to them.

As long those jars are not signed (and in some cases even if they are) you can rename jar file to zip and do all the changes you want.

You don't even need to rename them; JAR files can be opened with all ZIP applications just fine.

But two versions of a class seems like a bad design. Is this a class written by yourself or a colleague, or did you get the JAR files from the Internet?
