I am aware of the Checked and Unchecked Exception in Java.

In a multi-tiered environment, does unchecked Exception has a better performance over checked Exception?

    Absolutely zero performance difference. They're both just Exceptions. Checked/unchecked is purely a compile-time concept. Commented Nov 15, 2015 at 5:06

Checked-/unchecked-ness is purely a compile-time concept.

is unchecked exception " compile-time concept" ??
As far as I can see, 11.3. Run-Time Handling of an Exception draws no distinction between unchecked and checked exceptions - it doesn't even mention the terms.
@Rehman A checked exception is verified by the compiler to be either caught (try-catch) or listed in the throws clause of the method. There is no run-time check for that. See "Compile-Time Checking of Exceptions" and "Run-Time Handling of an Exception" in the JLS. Therefore, the difference between checked and unchecked is a compile-time concept.
Thanks all for the answer. :-)
