Java守护线程用法实例分析

Java守护线程用法实例分析

本文实例讲述了java守护线程用法。分享给大家供大家参考，具体如下：

一 点睛

针对守护线程，只要有一个用户线程在执行，这个进程就不会结束。

当线程中只剩下守护线程时，JVM会自动退出，反之，如果还有其他任何用户线程存在，JVM都不会退出。

二 代码

public class ThreadDaemon

{

public static void main( String args[] )

{

ThreadTest t = new ThreadTest();

Thread tt = new Thread( t );

tt.setDaehttp://mon( true ); // 设置后台运行

tt.start( );

try

{ // 睡眠1毫秒，避免可能出现的没有输出的现象

Thread.sleep( 1 );

}

catch( InterruptedException e )

{

e.printStackTrace();

}

}

}

class ThreadTest implements Runnable

{

public void run()

{

for( int i = 0; true; ++i )

{

System.out.println( i + " " + Thread.currentThread().getName()

+ " is running." );

}

}

}
