please suggest me the good and quick tutorials for JUnit, ant, subversion, log4j.
i found so much stuff in google, but i dont know which is best to learn them quickly.
can we learn each of them in 3 or 4 hours. if yes, please suggest me some best stuff.
You aren't likely going to learn enough for an interview in a couple hours. At least not with a good interviewer. They will ask questions to see whether you worked with the tools not just that you know "Ant is a build tool."
