导读：public class MyThread implements Runnable { int i = 0 ; @Override void run() { while ( true ) { synchronized ( this ) { // TODO Auto-generated method stub System.out.println(Thread.currentThread().getName() + " " + i); if (i++ 50 ) { break

public class MyThread implements Runnable {

    int i = 0;

    @Override
    void run() {

        while (true) {
            synchronized (this) {
                // TODO Auto-generated method stub
                System.out.println(Thread.currentThread().getName() + " " + i);

                if (i++ > 50) {
                    break;
                }

                Thread.yield();

                try {
                    Thread.sleep(10);
                } catch (InterruptedException e) {
                     TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }
}

class Test { static main(String[] args) { TODO Auto-generated method stub MyThread myThread = new MyThread(); Thread thread1 = Thread(myThread); thread1.setPriority(Thread.MAX_PRIORITY); thread1.setName("thread1"); thread1.start(); Thread thread2 = Thread(myThread); thread2.setPriority(Thread.MAX_PRIORITY); thread2.setName("thread2"); thread2.start(); } }

运行结果

thread1 0
thread1 1
thread1 2
thread1 3
thread1 4
thread1 5
thread1 6
thread1 7
thread2 8
thread2 9
thread1 10
thread1 11
