java158-线程的常用方法yield，优先级

    //线程
    public class test102 extends Thread{
        public void run(){
            while (true){
                System.out.println("我是线程1"+this.getName());
                try {
                    Thread.sleep( 1000 );
                }catch (InterruptedException e){
                    e.printStackTrace();
                }
            }
        }
    }

    //线程
    public class test103 extends Thread{
        public void run(){
            while (true){
                System.out.println("我是线程2"+this.getName());
                try {
                    Thread.sleep( 1000 );
                }catch (InterruptedException e){
                    e.printStackTrace();
                }
            }
        }
    }

测试类

    public class test105 {
        public static void main(String[] args){
            test102 one=new test102();
            test103 two=new test103();
            one.setName("线程1");
            one.setName( "线程2" );
            //设置线程的优先级
            two.setPriority( Thread.MAX_PRIORITY );
            one.setPriority( Thread.MIN_PRIORITY );
            //线程暂停thread.yield
            one.start();
            two.start();
            System.out.println( "我是主方法" );
        }
    }
