一、Thread類的構造方法
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種創建線程的方法：
（1） 繼承Thread類（java.lang.Thread）
public class Thread extends Object implements Runnable
這種方法是將類聲明為Thread的子類。該子類應重寫Thread類的run方法。接下來可以分配并啟動該子類的實例。
實例一：
- public class ThreadTest02 extends Thread{
-
- public void run(){
- for(int i=0; i<10; i++){
- System.out.println("線程"+Thread.currentThread().getName()+"extends Thread is running..."+i);
- }
- System.out.println("線程"+Thread.currentThread().getName()+"執行結束，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();
- }
-
- }
運行結果：
（2）利用Runnable接口（java.lang.Runnable)
這種方法是聲明實現Runnable接口的類。該類然后實現run方法。然后可以分配該類的實例，在創建Thread時作為一個參數來傳遞并啟動
實例二：
- public class ThreadTest02 implements Runnable{
-
- public void run(){
- for(int i=0; i<10; i++){
- System.out.println("線程"+Thread.currentThread().getName()+"implements Runnable interface is running..."+i);
- }
- System.out.println("線程"+Thread.currentThread().getName()+"執行結束，退出！");
- }
-
- public static void main(String[] args) {
- // TODO Auto-generated method stub
- ThreadTest02 t = new ThreadTest02();
- Thread thread = new Thread(t);
- thread.start();
- }
-
- }
