 两种方式:

1.继承Thread

2.实现Runnable

 

 1.

class MyThread extends Thread{
    public static int num = 0;
    
    @Override
    public void run() {
        // TODO Auto-generated method stub
        while(num<100) {
            System.out.println(Thread.currentThread().getName() + " -> "+ num++);
        }
    }
}

public class Test {
    public static void main(String[] args) {
        MyThread thread01 = new MyThread();
        MyThread thread02 = new MyThread();
        thread01.start();
        thread02.start();
    }
}

2.

class YourThread implements Runnable {
    private static int num = 0;

    @Override
    public void run() {
        // TODO Auto-generated method stub
        while (num < 100) {
            System.out.println(Thread.currentThread().getName() + " -> " + num++);
        }
    }
}

public class Test {
    public static void main(String[] args) {
        Thread thread01 = new Thread(new YourThread(),"t01");
        Thread thread02 = new Thread(new YourThread(),"t02");
        thread01.start();
        thread02.start();
    }

}

 

     

这种同步问题不会每次都出现.
