Can someone explain me difference between 'throw' and 'throws' in Exception Handling? what is the need of 'throws'?

Question

Would be great if someone explains with simple example.. Why do we need 'throws'? Why throw is not enough?

Answer 1

@throws is something like a warning. I'll try to explain it with methods:
If you call a method that is annotated with @throws the compiler knows that this call must be surrounded by try/catch.
throw is the keyword to actually throw a new exception in the method that is annotated with @throws.
