Checked and Unchecked Exception

[nitin sethi]

Could anyone confirm if the below is the exact classification for checked and unchecked exception?


1. Throwable (checked)
1.1 Error (unchecked)
1.1.1 unchecked hierarchy
1.2 Exception (checked)
1.2.1 checked hierarchy
1.2.2 RuntimeException (unchecked)
1.2.2.1 unchecked hierarchy

Yes your classification is correct.
In other words

Unchecked Exception = (Error and its subclass Exception + Runtime and its subclass Exception ).

Checked Exception = (Throwable Exception - Unchecked Exception).

In simple words, Any Exception which is sub-class or inherited from RuntimeException is unchecked Exception and doesn't require to be declared on throws clause. rest are checked exceptions.
