difference b/w Runtime and compile time exceptions?

[Naveen Megharaj]

how to know whether an Exception is a Runtime exception or Compile time exception....? How to differentiate between them......?its confusing me a lot.......!!!

If its a subclass of java.lang.RuntimeException, then it means its RuntimeException. Having said that, you don't usually need to catch runtime exceptions, they wouldn't complain either. Whereas regular exceptions, you need to handle gracefully. You can refer the docs to see all the pre-defined RuntimeExceptions in Java such as, ArithmeticException, and the infamous NullPointerException.

There is no such thing as a compile time exception. All exceptions occur at runtime. Compile time errors are different. There is a website about errors here.

Nice site! If you were here, I'd give you a high five. Since you are not, I will do the distance high five in my mind.

Thank you. High fifty-five maybe to the people who compiled that site, then
