一、线程对象的基本操作

二、获取线程对象

package com.bjpowernode.java.thread;
public class ThreadTest04 {
    public static void main(String[] args) {
        Thread currentThread = Thread.currentThread();
        System.out.println(currentThread.getName());
        //创建线程对象
        MyThread2 t1 = new MyThread2();
        //设置名字
        t1.setName("t1");
        //获取线程名字
        System.out.println(t1.getName());
        MyThread2 t2 = new MyThread2();
        t2.setName("t2");
        t2.start();
        t1.start();
        for (int i=0;i<100;i++){
            System.out.println(currentThread.getName()+"-->"+i);
        }
    }
}
class MyThread2 extends Thread{
    @Override
    public void run() {
        for (int i=0;i<1000;i++){
            Thread currentThread = Thread.currentThread();
            System.out.println(currentThread.getName()+"-->"+i);
        }
    }
}

三、sleep方法

重点：静态方法，让当前线程进入休眠

package com.bjpowernode.java.thread;
/*
面试题
 */
public class ThreadTest07 {
    public static void main(String[] args) {
        Thread t = new MyThread3();
        t.setName("t");
        t.start();
        try {
            //这行代码会让线程t进入休眠吗？
            //不会，让当前线程main进入休眠
            t.sleep(1000 * 5);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
class MyThread3 extends Thread{
    @Override
    public void run() {
        for (int i=0;i<1000;i++){
            System.out.println(Thread.currentThread().getName()+"--->"+i);
        }
    }
}

四、终止线程

1.stop()——过时

2.true和false

package com.bjpowernode.java.thread;
public class ThreadTest10 {
    public static void main(String[] args) {
        MyRunnable4 r = new MyRunnable4();
        Thread t = new Thread(r);
        t.setName("t");
        t.start();
        //等5秒
        try {
            Thread.sleep(1000*5);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        //终止线程
        r.run = false;
    }
}
class MyRunnable4 implements Runnable{
    boolean run = true;
    @Override
    public void run() {
        for (int i=0;i<10;i++){
            if (run){
                System.out.println(Thread.currentThread().getName()+"--->"+i);
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }else {
                return;
            }
        }
    }
}
