public class ThrowableDemo {

   public static void main(String[] args) {

      try {
         raiseException();
      } catch(Throwable e) {
         // print Message of throwable	  
         System.err.println(e.getMessage());
      }
   }
  
   // throws Throwable  
   public static void raiseException() throws Throwable {
      throw new Throwable("This is the new Exception"); 
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

This is the new Exception
