本文实例讲述了Java线程操作的常见方法。分享给大家供大家参考，具体如下：

一 线程名称的操作

1 代码

public class GetNameThreadDemo extends Thread{ public void run() { for( int i = 0; i < 5; ++i ) { printMsg(); try { Thread.sleep(1000); // 睡眠1秒 } catch( InterruptedException e ) { e.printStackTrace(); } } } public void printMsg() { // 获得运行此代码的线程的引用 Thread t = Thread.currentThread(); String name = t.getName(); System.out.println( "name = " + name ); } public static void main( String[] args ) { GetNameThreadDemo t1 = new GetNameThreadDemo(); t1.start(); for( int i = 0; i < 5; ++i ) { t1.printMsg(); try { Thread.sleep(1000); // 睡眠1秒 } catch( InterruptedException e ) { e.printStackTrace(); } } }}

2 运行

name = main
name = Thread-0
name = main
name = Thread-0
name = main
name = Thread-0
name = main
name = Thread-0
name = main
name = Thread-0

二 设置与获取线程名称

1 代码

public class GetSetNameThreadDemo implements Runnable{ public void run( ) { Thread temp = Thread.currentThread( );//获取执行这条语句的线程实例 System.out.println("执行这条语句的线程名字:" + temp.getName( )); } public static void main(String[] args) { Thread t = new Thread(new GetSetNameThreadDemo( )); t.setName("线程_范例演示"); t.start(); }}

三 判断线程是否启动

1 代码

public class StartThreadDemo extends Thread{ public void run() { for( int i = 0; i < 5; ++i ) { printMsg(); } } public void printMsg() { // 获得运行此代码的线程的引用 Thread t = Thread.currentThread(); String name = t.getName(); System.out.println( "name = " + name ); } public static void main( String[] args ) { StartThreadDemo t = new StartThreadDemo(); t.setName( "test Thread" ); System.out.println( "调用start()方法之前 , t.isAlive() = " + t.isAlive() ); t.start(); System.out.println( "刚调用start()方法时 , t.isAlive() = " + t.isAlive() ); for( int i = 0; i < 5; ++i ) { t.printMsg(); } // 下面语句的输出结果是不固定的，有时输出false，有时输出true System.out.println( "main()方法结束时 , t.isAlive() = " + t.isAlive() ); }}

2 运行

调用start()方法之前 , t.isAlive() = false
刚调用start()方法时 , t.isAlive() = true
name = main
name = main
name = main
name = test Thread
name = main
name = test Thread
name = main
name = test Thread
main()方法结束时 , t.isAlive() = true
name = test Thread
name = test Thread
