 public static void main(String[] args) {
   try {
       throw new Exception("My Exception");
   } catch (Exception e) {
       System.err.println("Caught Exception");
       System.err.println("getMessage():" + e.getMessage());
       System.err.println("getLocalizedMessage():"
       + e.getLocalizedMessage());
       System.err.println("toString():" + e);
       System.err.println("printStackTrace():");
       e.printStackTrace();
   }
 }
 }

Caught Exception
getMessage():My Exception
getLocalizedMessage():My Exception
toString():java.lang.Exception: My Exception
printStackTrace():
java.lang.Exception: My Exception
