20220521_线程最常用的方法-优快云博客

本文展示了如何在Java中创建线程并使用`Thread.currentThread()`获取当前线程，以及通过`Thread.sleep()`实现线程休眠。示例包括自定义线程类和线程休眠的用法，详细解释了线程执行流程。

线程类

public class MyThread extends Thread{
    public MyThread() {
    }

    public MyThread (String name){
        super(name);

    }

    @Override
    public void run() {
        for (int i = 1; i < 6; i++) {
            System.out.println(Thread.currentThread().getName()
                    +" thread is running~~~"+i);

        }
    }
}

执行类
涉及方法，getName，setName，Thread.currentThread()

public class ThreadApiDemo1 {
    public static void main(String[] args) {
        Thread th1 = new MyThread();
        th1.start();
        System.out.println(th1.getName());

        Thread th2 = new MyThread();
        th2.start();
        System.out.println(th2.getName());

        Thread th3 = new MyThread();
        th3.setName("No.3");
        th3.start();

        Thread th4 = new MyThread("No.4");
        th4.start();

        Thread th = Thread.currentThread();
        String thName = th.getName();

        for (int i = 1; i < 6; i++) {
            System.out.println(thName+" thread is running~~~"+i);
        }

    }
}

线程休眠方法

public class ThreadApiDemo2 {
    public static void main(String[] args) throws InterruptedException {

        Thread th = Thread.currentThread();
        String thName = th.getName();

        for (int i = 1; i < 6; i++) {
            System.out.println(thName+" thread is running~~~"+i);
            if (i == 3){
                Thread.sleep(3000);
            };
        }
    }
}
