【java多线程与并发库】---传统java多线程<2> 线程创建方式

一、Thread类的构造方法

public Thread();

public Thread (Runnable target);

public Thread (Runnable target,String name);

public Thread (String name);

public Thread (ThreadGroup group,Runnable target);

public Thread (ThreadGroup group,Runnable target,String name);

public Thread (ThreadGroup group,String name);

 

二、Java中提供了2种创建线程的方法：

（1）   继承Thread类（java.lang.Thread）

public class Thread extends Object implements Runnable

 

这种方法是将类声明为Thread的子类。该子类应重写Thread类的run方法。接下来可以分配并启动该子类的实例。

 

 实例一：

public class ThreadTest02 extends Thread{ public void run(){ for(int i=0; i<10; i++){ System.out.println("线程"+Thread.currentThread().getName()+"extends Thread is running..."+i); } System.out.println("线程"+Thread.currentThread().getName()+"执行结束，退出！"); } public static void main(String[] args) { // TODO Auto-generated method stub Thread t1 = new ThreadTest02(); t1.setName("T1"); Thread t2 = new ThreadTest02(); t2.setName("T2"); t1.start(); t2.start(); } }

运行结果：

 

 

（2）利用Runnable接口（java.lang.Runnable)

 这种方法是声明实现Runnable接口的类。该类然后实现run方法。然后可以分配该类的实例，在创建Thread时作为一个参数来传递并启动

 

实例二：

public class ThreadTest02 implements Runnable{ public void run(){ for(int i=0; i<10; i++){ System.out.println("线程"+Thread.currentThread().getName()+"implements Runnable interface is running..."+i); } System.out.println("线程"+Thread.currentThread().getName()+"执行结束，退出！"); } public static void main(String[] args) { // TODO Auto-generated method stub ThreadTest02 t = new ThreadTest02(); Thread thread = new Thread(t); thread.start(); } }

 

运行结果：
