Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.

I don’t know the key to success, but the key to failure is trying to please everybody.
