Java中多线程的使用（超级超级详细）+多线程的实现原理 2

public class Main {
    public static void main(String[] args) {
        MyThread myThread = new MyThread("one");
        myThread.start();
        int i=20;
        for (int i1 = i; i1 > 0; i1--) {
            System.out.println("主线程："+i1);
        }
    }
}

**public class MyThread extends java.lang.Thread{
    public MyThread(String name) {
        super(name);
    }
    @Override
    public void run() {
        int i=20;
        for (int i1 = 0; i1 < i; i1++) {
            System.out.println("辅线程"+i1);
        }
    }
}**
