什么是Java中的守护程序线程？
Java中的守护程序线程是在后台连续执行的线程。您可以使用setDaemon()方法设置线程守护程序。
示例
class adminThread extends Thread {
adminThread() {
setDaemon(true);
}
public void run() {
boolean d = isDaemon();
System.out.println("daemon = " + d);
}
}
public class ThreadDemo {
public static void main(String[] args) throws Exception {
Thread thread = new adminThread();
System.out.println("thread = " + thread.currentThread());
thread.setDaemon(true);
thread.start();
}
}输出结果
thread = Thread[main, 5, main]
