如何用JAVA语言实现计算机的重起和关机？

Question

我知道关机
Runtime.getRumtime.exec("RunDllEXE User.exe,exitwindow");别忘用TRY把他括起来

Answer 1

Answer 2

哦   当然了，那天很忙 public class ExitWindows extends JFrame implements ActionListener 
      {
       JButton exitWindows; 
       
       public ExitWindows()
             {
              super("ExitWindows");
              setSize(200,240);
              setDefaultCLoseOperation(JFrame.EXIT_ON_CLOSE);
                          
              exitWindows = new JButton("关机");
              exitWindows.AddactionListener(this);               JPanel pane = new JPanel();
                     pane.add(exitWindows);              setContentPane(pane);
              }
              
       public static void main(String[] args)
              {
               ExitWindows exit = new ExitWindows();
                           exit.show();
               }
     
       public void actionPerformed(ActionEvent evt)
              {
               Runtime r = Runtime.getRuntime();
               Process p = null;               Object src = evt.getSource();
               
               if(scr==exitWindows)
                 {
                  try{
                     r.exec("RUNDLL.EXIT user.exe,exitwindows");
                     p.waitFor();
                    }
                 catch(Exception en) {
                       System.out.printf(en.toString());
                 }
                }
               }
   }
 
   请着重看TRY的处理，因为程序可能有错误，我在网吧上网。。最好理解 做成自己想要的格式
