Thread的常用方法

一，常用方法

二，案例

 父类：

package ThreadLianXi;
 
import ThreadLianXi.ZhiLeiA;
 
public class Name {
    public static void main(String[] args)throws Exception{
        Thread t1 =new ZhiLeiA("1号");
        //修改名字
        t1.setName("1号");
        t1.start();
 
        //join方法；让当前方法先执行完
        t1.join();
        
        //获取线程名字
        System.out.println(t1.getName());//原名：Thread-0//1号
 
 
        Thread t2 =new ZhiLeiA("2号");
        t2.start();
        System.out.println(t2.getName());//原名：Thread-1//2号
 
        //获取线程对象
        Thread m =Thread.currentThread();
        System.out.println(m.getName());//main
 
        //暂停5秒(记得在开头写上：throws Exception)
        for (int i = 0; i <4 ; i++) {
            System.out.println(m.getName()+"线程输出"+i);
            if (i==2){
                Thread.sleep(5000);
            }
        }
 
 
 
    }
}

子类：

package ThreadLianXi;
 
public class ZhiLeiA extends Thread {
    public ZhiLeiA(String name){
        super(name);//为线程设置名字
    }
    @Override
    public void run(){
        Thread m =Thread.currentThread();
        for (int i = 0; i <4 ; i++) {
            System.out.println(m.getName()+"线程输出"+i);
        }
 
    }
}
