判断线程是否执行完毕

import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; public class Test { public static void main(String args[]) throws InterruptedException { ExecutorService exe = Executors.newFixedThreadPool(3);...

通过Thread类中的isAlive()方法判断线程是否处于活动状态; 线程启动后,只要没有运行完毕,都会返回true; 除了上面一种还有两种; 1,通过Thread.activeCount()方法判断当前线程的线程组中活动线程的数目,为1时其他线程运行完毕; 2,通过jav...

List arr = new List(); for (int i =0; i

List arr = new List(); for (int i =0; i

给你一个例子参考下 import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; public class Test { public static void main(String args[]) throws InterruptedException { ExecutorService exe = Executors.new...

创建线程时 ... thread1 = new MyThread(false); thread1 -> FreeOnTerminate = false; // 不自动释放线程 thread1 -> Resume(); // 开始执行线程 ... 在Execute方法中循环检查Terminated是否为true,如果为true,则退出循环. 在主线程中结束线程...

其中一个线程?使用类变量判断就可以了。 class A{ static boolean aStop = false; static void test(){ new AThread().start(); while(! aStop){ } System.out.println("AThread stoped."); } class AThread extends Thread{ public void run()...

class ReadFileThread implements Runnable{ int i=0; public ReadFileThread(int i){ this.i=i; } public void readFileThread(int i){ try{ //.....read file(i); } catch(Exception e){ e.printStackTrace(); } } public void run(){ try { t...
