How can I develop java code for all platforms/OS ?.

[Praveen Kumar]

Hi All,


In an interview, I faced above question and I answered that JVM is platform dependent and there is separate JVM for each OS. So we need to run the code in respective JVM then we can use same java code in
all OS. I hope i said is correct answer .. Then interviewer asked me that Do we have any rules to follow in java coding ?. Here I am not aware the rules we need to follow.

Please tell me what rules we need to take care when ever your developing java code for all platforms ?.

Avoid OS specific features, eg thread priorities, use of \n and \r, use of \\ or / between files, use of ; or : between paths.
