Synchronization

Here's the new code snippet with a single keyword addition, synchronized, to fix the race condition:

class Task implements Runnable {
static int sum = 0;
synchronized public void run() { ++sum; }
}
public class Main {
public static void main(String args[]) throws Exception {
Task task = new Task();
for (int i = 0; i < 10000; i++) {
new Thread(task).start();
