this Error Appear when i extend exception class in eclipse indigo, but it works properly in net-beans 8.2

package com;// error 


public class ex extends Exception{


    private static final long serialVersionUID = 1L;

    public ex(String string) {
        System.out.println(string);
    }

}

Answer 1

There is nothing wrong in the posted code.

Eclipse Indigo should also work fine for the code you have posted above. Possibly something else in the package/Project in same workspace which is giving that error ?
