public static void main(String[] args) {
new Person1().start();
new Person2().start();
}
}
class Person1 extends Thread{
@Override
public void run() {
for (int i = 0; i < 10000; i++) {
System.out.println("who are you");
}
}
}
class Person2 extends Thread{
@Override
public void run() {
for (int i = 0; i < 10000; i++) {
