java线程的一些基本方法

sleep方法：
Thread.sleep(5)  单位是毫秒，意思是把当前线程休眠5毫秒.

public class Test {
    
	public static void main(String[] args) {
		Thread myThread = new Thread(new MyThread(),"myThread");
		myThread.start();
		for (int i = 0; i < 1000; i++) {
			if (i % 2 == 0) {
				// 主线程休眠5毫秒
				try {
					Thread.sleep(5);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
			System.out.println("test" + i);
		}
	}
	
}

class MyThread implements Runnable {
	@Override
	public void run() {
		for (int i = 0; i <= 1000; i++) {
			System.out.println(i);
		}
	}
}

yield 方法:
该方法是让出当前线程，让其他线程执行

public class Test {
    
	public static void main(String[] args) {
		MyThread myThread1 = new MyThread("t1");
		MyThread myThread2 = new MyThread("t2");
		myThread1.start();
		myThread2.start();
	}
	
}

class MyThread extends Thread {
	public MyThread(String arg){
		super(arg);
	}
	@Override
	public void run() {
		for (int i = 0; i <= 100; i++) {
			System.out.println(getName()+":"+i);
			if (i % 10 == 0) {
				// 注意:一定是Thread.yield(), 不要直接调用yield()方法
				// 线程让出一段时间，等到cpu执行该线程时在执行
				Thread.yield();
			}
		}
	}
}
