Thread: Please solve my problem

I have some problem in that code...

 import java.io.*;
class Demo{
        public static void main(String args[]){
                try{
                        //
                }catch(ArithmeticException e){
 
                }
                //----------------------------
                try{
                        //
                }catch(InterruptedException e){  //Line 1
 
                }               
                //------------------------------
                try{
                        //
                }catch(Exception e){  //Line 2****
 
                }               
        }
}

In that code only Line 1 is compile error.But I think Line 2 also compile error.Because InterruptedException and Exception are the checked Exception in compile time....Please help me to solve that..

In that code only Line 1 is compile error.

The reason why you have a compilation error with that line is because there is no code/statements
that might be Interrupted by another process or thread.

Try to create another thread and run it, then join your main thread inside the try before line 1
that will make no compilation error. Because your main thread will wait
for the other thread to finish first before running/execute the next statement.
But for some instance that your main thread will be interrupted by another thread,
That's the InterruptedException occurs.

But in your code, it is clear that there will be no InterruptedExceptions since
you only have comment with that block before line 1

I think "Exception"(I mean top in the Throwable class hierachy) checked in compile time.So any thread when we use compiler must give the error in that case.can you explain why it doesn't give error?? I'm new for Thread,so please explain it in a bit simple......
