Javac: compiling java file only if necessary

hello,

i have the problem that i want to compile a java file only if there are any changes...i don't want to use any other "tools" than the compiler (javac) but no third party apps...is there a solution for my problem...perhaps with a little shell script? or is there an easier solution? thx for replies
