Check whether the Java file is changed? Check what?

Maybe you mean check whether the Java file is newer than the class file? You'd just use the operating system's last modified time for the two files. If you're doing this in Java, the java.io.File class has a method to check this; otherwise, "ls -l" or "dir" will do the trick.

Hello,

Exactly. That what ANT will do. It checks the time stamp .class file with .java file. if the timestamps are diffe then new compilation for that file will be made.

if some one make touch of the .class file then .... ? it recompiles again.
