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" );
}
}
