java并发之获取线程状态信息

通过Thread.currentThread获取当前线程的基本信息

 Thread.State

package chapter1;

public class ThreadInfo {

    public static void main(String[] args){
        Thread threads[] = new Thread[10];
        for (int i=0; i< 10;i++){
            threads[i] = new Thread(new Number(i));
            threads[i].setName("thread:"+i);
            if( (i%2) == 0){
                threads[i].setPriority(Thread.MIN_PRIORITY);
            }else{
                threads[i].setPriority(Thread.MAX_PRIORITY);
            }
        }
        for (int i=0; i< 10;i++){
            threads[i].start();
        }
        boolean finish = false;
        while (!finish){

            for (int i=0; i< 10;i++){
                System.out.printf("%s status:%s\n",threads[i].getName(),threads[i].getState());
            }
            finish = true;
            for (int i=0; i< 10;i++){
                finish = finish &&(threads[i].getState()== Thread.State.TERMINATED);
            }

        }


    }
