any direction would be gr8
I need to write a program that launches 1000 threads. Each thread adds 1 to a variable sum that is initially 0. I need to pass sum by reference to each thread. In order to pass by reference, define an Integer wrapper object to hold the sum. Run the program with and without synchronization to see the effects.
Ex output:
At thread 1 sum = 0;
At thread 2 sum = 1,
Etc…
im lost on how to start..I... -

well I must say that you guys love to make someone who is trying to learn feel STUPID..just because you have a lot more experience or TIME to understand the concepts here...doesnt mean everyone does...
here is the code I have that throws an exception which in turn kills the app...
...Code:import javax.swing.JOptionPane; public class Grades { public Grades() {Leave a comment:

This Runs and kills the app when you put in an invalid number
But What I want is for it to stop and tell the user and then they can continue...how would I do that?
can you explain the " SUPER(S)" at the end?
