Point1 point = new Point1();
for (int i = 0; i < 10; i++) {
int finalI = i;
Thread thread = new Thread(() -> {
int move = point.move(1 + finalI, 1 + finalI);
int origin = point.distanceFromOrigin();

System.out.println(Thread.currentThread().getName());
System.out.println(origin);

});
//
thread.start();
//Thread.sleep(100);
}

是循环太快了么？

加了sleep 就顺序了
