currentThread()方法返回代码段正在被哪个线程调用

package com.stono.thread2.page16;public class MyThread extends Thread{    public MyThread() {        System.out.println("构造方法的打印："+Thread.currentThread().getName());    }    @Override    public void run() {        System.out.println("run方法的打印："+Thread.currentThread().getName());    }        public static void main(String[] args) {        MyThread myThread = new MyThread();//        myThread.start();//        构造方法的打印：main//        run方法的打印：Thread-0        myThread.run();//        构造方法的打印：main//        run方法的打印：main    }}

 注意与this.getName()的区别

package com.stono.thread2.page16;public class CountOperate extends Thread{    public CountOperate() {        System.out.println("CountOperate---begin");        System.out.println("Thread.currentThread().getName()="+Thread.currentThread().getName());        System.out.println("this.getName()="+this.getName());        System.out.println("CountOperate---end");    }    @Override    public void run() {        // super.run();        System.out.println("run---begin");        System.out.println("Thread.currentThread().getName()="+Thread.currentThread().getName());        System.out.println("this.getName()="+this.getName());        System.out.println("run---end");            }        public static void main(String[] args) {        CountOperate c = new CountOperate();        Thread t1 = new Thread(c);        t1.setName("A");        t1.start();//    CountOperate---begin//    Thread.currentThread().getName()=main//    this.getName()=Thread-0//    CountOperate---end//    run---begin//    Thread.currentThread().getName()=A//    this.getName()=Thread-0//    run---end    }}

 this.getName()是Thread.getName()方法，源码：

public final String getName() {        return new String(name, true);    }
