compile error: unreachable statement try{

but why do i get this?
if there was not a throw statement just after the try block then isnt case 2 and case 3 unreachable statement as they are never reach as x is 1

on line 10 you throw an exception, hence, JVM will exit the method. the try-statement on line 11 will NEVER be reached.

i know that....but what is there to give an error in this?

[Linda Wiklund]

Code that never will be reached, never used is redundant. It should not bee there. You'll get the same error if you have code after a return statement.
