1、currentThread()
currentThread()方法返回的是对当前正在执行线程对象的引用。
package thread;
/**
* 线程类的构造方法、静态块是被main线程调用的，而线程类的run()方法才是应用线程自己调用的
*
*/
public class MyThread04 extends Thread
{
static
{
System.out.println("静态块的打印：" +
Thread.currentThread().getName());
} public MyThread04()
{
System.out.println("构造方法的打印：" +
Thread.currentThread().getName());
} public void run()
{
System.out.println("run()方法的打印：" +
Thread.currentThread().getName());
} public static void main(String[] args)
{
MyThread04 mt = new MyThread04();
mt.start();
} }
静态块的打印：main
构造方法的打印：main
run()方法的打印：Thread-0
2、this.XXX() 与 Thread.currentThread.XXX()或Thread.XXX()
public class MyThread05 extends Thread
{
public MyThread05()
{
System.out.println("MyThread5----->Begin");
System.out.println("Thread.currentThread().getName()----->" +
Thread.currentThread().getName());//这种调用方式表示的线程是正在执行Thread.currentThread.XXX()所在代码块的线程
System.out.println("this.getName()----->" + this.getName());//这种调用方式表示的线程是线程实例本身
System.out.println("MyThread5----->end");
} public void 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)
{
MyThread05 mt5 = new MyThread05();
mt5.start();
} }
MyThread5----->Begin
Thread.currentThread().getName()----->main
this.getName()----->Thread-0
MyThread5----->end
run----->Begin
Thread.currentThread().getName()----->Thread-0
this.getName()----->Thread-0
run----->end
