- by Eslam
Given:
public class Thread1 {
int x = 0;
public class Runner implements Runnable {
public void run() {
int current = 0;
for (int i = 0; i < 4; i++) {
current = x;
System.out.print(current + " ");
x = current + 2;
}
}
}
public void go() {
Runnable r1 = new Runner();
new Thread(r1).start();
new Thread(r1).start();
}
public static void main(String[] args) {
new Thread1().go();
}
}
