I have to develop a software and it should run on windows, mac and linux, so i was thinking of developing it in java using netbeans :-/

I have windows OS,
would the jar file generated in windows run properly on mac and linux? and is there any specific notes and requirements that should be considered :?:

thanks in advance !

It *should*. Although I have personally occasionally had slight GUI issues when trying to run the same jar on Mac & Windows. But yes, the idea is that it will do so. If I were you, I'd test it on multiple platforms to be sure.
