[Java] Thread-01 sleep-join-yield

eclipse调整格式快捷键 与 搜狗输入法里的切换简繁快捷键是ctrl+shift+F 跟eclipse冲突了。关闭搜狗输入法快捷键即可。
public class TestThread1 {
    public static void main(String args[]) {
        Runner1 r = new Runner1();
        r.start();
        // r.run();
        // Thread t = new Thread(r);
        // t.start();

        for (int i = 0; i < 100; i++) {
            System.out.println("Main Thread:------" + i);
        }
    }
}

// class Runner1 implements Runnable {
class Runner1 extends Thread {
    public void run() {
        for (int i = 0; i < 100; i++) {
            System.out.println("Runner1 :" + i);
        }
    }
}
// 马老师心得 : 能使用接口,就尽量使用接口,别从 Thread 继承,因为缺少灵活性。
