Throw an exception

[raj kala]

wont throwing of error stop the entire program?

[Ricky Clarkson]

Throwing exceptions only stops programs if nothing above them in the call stack can handle the exception (and if the current thread is the only active non-daemon thread).

Perhaps just 'return;' would help you.

No, if you catch it at the appropriate place. For example in the onOk method.
