线程的调度

线程的调度

线程的优先级等级

MAX_PRIORITY:10
MIN_PRIORITY:1
NORM_PRIORITY:5

线程优先级涉及的方法

getPriortiy()：返回线程的优先级
setPriority(int newPriortiy)：改变线程的优先级

线程创建时继承父线程的优先级
第优先级只是获得调度的概率低，并非一定是在高优先级线程之后才被调用。

package threadStudy;

public class Main {
	public static void main(String[] args) {
		MyThread mythread = new MyThread("MyThread");
		mythread.setPriority(Thread.MAX_PRIORITY);
		mythread.start();
		
		
		Thread.currentThread().setName("MainThread");
		Thread.currentThread().setPriority(Thread.MIN_PRIORITY);

		for(int i = 0; i <= 100; i++){
			System.out.println(Thread.currentThread().getName()+"-"+i);
		}
		
		
	}
}

package threadStudy;

public class MyThread extends Thread{
	
	private String threadName;
	
	public MyThread(String threadName){
		super(threadName);
	}
	
	public void run(){
		for(int i = 0; i <= 100; i++){
			System.out.println(this.currentThread().getName()+"***"+i);
		}
		
		
	}
}
