When I export the projecto to a JAR it works but it export an old version of my code for example:
Old Version:
System.out.println("Hellow World");
New Version:
System.out.println("Hellow World");
System.out.println("Version 2");
and then when I export the project it works and I run the JAR it throws me just
"Hellow World" not "Hellow World Version 2".
Someone can help me to know why it happens or how to solve it?

Hi

I can think of perhaps ten different reasons why almost all down to user trouble; you are not doing what you think you are doing. The easiest way to debug it is to delete the JAR file and confirm that you have killed the old program before recreating and seeing whether you have a new one. If not delete a *.java file to discover how many *.java files you have.
