I still get the answer of 'Final Result is 2'. You have all your classes in separate files called work.java test.java and result.java. Having all in one work.java results in a compilation error with Java 1.6 and 1.5. You compiled every file with "javac work.java", "javac test.java" and "javac result.java" After this you changed in result.java the code and recompiled work.java. So the class-file result.class is not changed to reflect your changes of count-variable, because you have not orderd javac to do it. Therefore is e.g. and ant-buildfile which checks if anything has to be recompiled. An IDE would do this job for you.
