Java中如何使用守護線程

今天就跟大家聊聊有關Java中如何使用守護線程，可能很多人都不太了解，為了讓大家更加了解，小編給大家總結了以下內容，希望大家根據這篇文章可以有所收獲。

一 點睛

針對守護線程，只要有一個用戶線程在執行，這個進程就不會結束。

當線程中只剩下守護線程時，JVM會自動退出，反之，如果還有其他任何用戶線程存在，JVM都不會退出。

二 代碼

public class ThreadDaemon{  public static void main( String args[] )  {   ThreadTest t = new ThreadTest();   Thread tt = new Thread( t );   tt.setDaemon( true ); // 設置后臺運行   tt.start( );   try   { // 睡眠1毫秒，避免可能出現的沒有輸出的現象     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." );   }  }}

三 運行
