在Java编程中，如何显示所有正在运行的线程？
以下示例演示如何使用getName()方法显示所有正在运行的线程的名称。
package com.yiibai;
public class DisplayRunningThread extends Thread {
public static void main(String[] args) {
DisplayRunningThread t1 = new DisplayRunningThread();
t1.setName("thread1");
t1.start();
DisplayRunningThread t2 = new DisplayRunningThread();
t2.setName("thread2");
t2.start();
ThreadGroup currentGroup = Thread.currentThread().getThreadGroup();
int noThreads = currentGroup.activeCount();
Thread[] lstThreads = new Thread[noThreads];
currentGroup.enumerate(lstThreads);
for (int i = 0; i < noThreads; i++){
System.out.println("Thread No:" + i + " = " + lstThreads[i].getName());
}
}
}
上述代码示例将产生以下结果 -
Thread No:0 = main
Thread No:1 = thread1
Thread No:2 = thread2
