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?

2Absolutely zero performance difference. They're both just `Exception`s. Checked/unchecked is purely a compile-time concept. – Andy Turner Nov 15 '15 at 05:06

Don't look at me, I didn't DV. And I'm probably the only person who would be notified or notice on a comment on a 2-week-old question. – Andy Turner Nov 27 '15 at 15:59

1Good, because I have no particular incentive to lie; I could just stay quiet... Now, what is wrong with my answer? :) – Andy Turner Nov 27 '15 at 16:02

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

As far as I can see, [11.3. Run-Time Handling of an Exception](https://docs.oracle.com/javase/specs/jls/se7/html/jls-11.html#jls-11.3) draws no distinction between unchecked and checked exceptions - it doesn't even mention the terms. – Andy Turner Nov 15 '15 at 05:22

@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](https://docs.oracle.com/javase/specs/jls/se7/html/jls-11.html#jls-11.2)" and "[Run-Time Handling of an Exception](https://docs.oracle.com/javase/specs/jls/se7/html/jls-11.html#jls-11.3)" in the JLS. Therefore, the *difference* between checked and unchecked is a compile-time concept. – Andreas Nov 15 '15 at 05:28
