Exception:Exception as the name suggests anything that is unusal.For e.g. if i try to delete a file which doesn't exist then it is an exception.

Error:Error is caused if something is wrong with the program.For e.g. a syntax error,logical error or runtime error.

EXCEPTION: Any problem that can be handle by software is called exception.

ERRO: Any problem which can not handle by software like system get out of memmory is an error, and we can not fix it with software, is called ERROR.

Exception is unexpected even which is meean to be handled by developers writing code.
Error is caused if something is wrong with the program or is a flaw in the system.

Error is which nobody can guess when it occurs.  Exception can be guessed and can be handled. 

In Java Exception and Error are sub class of Throwable.  It is differentiated based on the program control. Error such as OutOfMemory Error which no programmer can guess and can handle it.  It depends on dynamically based on architectire, OS and server configuration.  Where as Exception programmer can handle it and can avoid application's misbehavior.  For example if your code is looking for a file which is not available then IOException is thrown.  Such instances programmer can guess and can handle it.
