用Java啟動外部程序?

Problem: Automatically close a program after a certain amount of minutes.

Solution: Here is what I came up with to solve my problem (works with Rhythmbox on Ubuntu):

package rhythmBox;

import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import java.util.concurrent.TimeUnit;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class closeRhythmBox extends JFrame implements ActionListener {

private static final long serialVersionUID = 1L;
private static final int WIDTH = 400;
private static final int HEIGHT = 300;
private JTextField minutesBox;

public static void main(String[] args) {
    new closeRhythmBox().setVisible(true);
}

public static void execKill(long minutes) throws InterruptedException {
    Thread.sleep(minutes*60*1000);
    try{
    Runtime.getRuntime().exec("pkill rhythmbox");
    System.exit(0);
        }
    catch (IOException ioe) {
          ioe.printStackTrace();
        }
}
public closeRhythmBox(){
    setTitle("Rythmbox Timer");
    setSize(WIDTH, HEIGHT);
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Container pane = getContentPane();
    pane.setLayout(new FlowLayout());

    JPanel box = new JPanel();
    box.setLayout(new FlowLayout());
    JButton startButton = new JButton("Start");
    startButton.addActionListener(this);
    box.add(startButton);
    box.add(new JLabel("Minutes Until Close"));
    box.add(minutesBox = new JTextField(20));

    pane.add(box);
    pack();

}

public void actionPerformed(ActionEvent e) {
    String textNum = minutesBox.getText();
    long minuteNum = Long.parseLong(textNum);
    if (e.getActionCommand().equals("Start")){
        try {
            execKill(minuteNum);
        } catch (InterruptedException e1) {
            e1.printStackTrace();
        }
    }
}   

}

最佳答案

你可能無法以這種方式啟動EXE。我認為這是打算使用默認應用程序打開一個文件,而不是自己運行一個應用程序 - 或者你剛剛運行到Windows安全性。

您可以使用Java.lang.Process運行帶參數的程序。
