java runnable 内部类_java 10-05 优先级 runnable 内部类

线程优先级

priorty

---------------------------------------------------------

1-10：从低到高

默认是5

------------------------------------------------------------------

class TenDemo5{

public static void main(String[] agrs) {

Thread T=Thread.currentThread();

//修改主线程的名称

T.setName("this is my thread");

String name= T.getName();

System.out.println("name="+ name);

//设置当前优先级

T.setPriority(10);

//当前的优先级

int p=T.getPriority();

System.out.println(p);

}

}

Runnable

-------------------------------------------------------

/* class TenRunnable{

public static void main(String[] agrs) {

//main 函数孵化新线程

Myrunnable r =new Myrunnable();

new Thread(r).start();

}

}

//implements 实现接口 Runnable实现类  降低耦合

class Myrunnable implements Runnable{

public void run(){

while(true){

System.out.println("Hello");

}

}

} */

//匿名类

class TenRunnable{

public static void main(String[] agrs) {

// new Thread(new Runnable()

// {

// public void run (){

// System.out.println("Hello");

// }

// }).start();

new Thread(){

public void run (){

System.out.println("Hello");

}

}.start();

}
