Hi,

The following code snippet would help java-novice. wear the compiler's hat and say the output for the code snippets

1.

2.

Try and tell in which cases the code in finally block will be executed

the code in the first case executes the finally block


try{
//some code
return;
}finally{

}

Which might mean something if there were any code in the finally block. Since there isn't, it seems a poor example to discuss.

Also, "be the compiler" has nothing to do with this. The compiler has no idea what "System.exit()" does - it just knows it's a method that can be called with the appropriate bytecode. It's the JVM that determines, at runtime, that System.exit() results in shutting down without executing finally.

Which is why
will compile, but
will complain about unreachable code.
