[vineet walia]

class exception1 extends Exception{}
class exception2 extends Exception{}

public class mye {

	public static void main(String str [])
	{
	    try {
	    	
	    	
	    	try {
				     throw new exception2();
				     
			} catch (exception2 e1) {
				System.out.println("exi1");
			}
			catch(exception1 e2){
				System.out.println("ex2");
			}
			finally{
				System.out.println("fi-1");
			}
		} catch (Exception e) {
			System.out.println("ex");
		}
	finally{
		System.out.println("fi-2");
	}
	
	}
}

can any body explain why this is giving error
this question is from exam lab ?

[Nitish Bangera]

Yeah because exception1 and exception2 are both checked exceptions and when you are catching a checked exception, there should be a statement in the try block which throws or declares that it throws that checked exception. I guess the explanation given by examlab is pretty much clears that point.

I think the error message is pretty self explainatory:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Unreachable catch block for exception1. This exception is never thrown from the try statement body
