如何在Java中停止命令行過程

Question

我有一個程序，允許用戶按下按鈕，然後運行命令行語句，用戶可以看到輸出。

我現在想知道在結束之前是否可以停止命令。 當我正常運行命令提示符時，我知道命令「ctrl + c」，但是，我不確定如何在java程序中執行此操作。

runButton.addActionListener(new ActionListener() { 
    public void actionPerformed(ActionEvent r) { 
     JFrame runFrame = new JFrame("Running process..."); 
     runFrame.setSize(500, 400); 
     runFrame.setDefaultCloseOperation(DISPOSE_ON_CLOSE); 
     runFrame.setLayout(null); 
     JButton somethingButton = new JButton("Stop"); 
     JButton closeButton = new JButton("Close"); 
     somethingButton.setBounds(65, 290, 105, 25); 
     closeButton.setBounds(335, 290, 105, 25); 
     JTextArea run = new JTextArea(); 
     JScrollPane runSP = new JScrollPane(run); 
     runSP.setBounds(65, 50, 375, 200); 
     run.setLineWrap(true); 
     run.setWrapStyleWord(true); 
     run.setEditable(false); 
     runFrame.add(runSP); 
     runFrame.add(somethingButton); 
     runFrame.add(closeButton); 
     runFrame.setVisible(true); 
     //Start of creating of command line stuff 
     Runtime runtime = Runtime.getRuntime(); 
     Process process = null; 
     try { 
      process = runtime.exec("ping riot.de"); 
     } catch (IOException e1) { 
      System.err.print("Error: " + e1); 
      e1.printStackTrace(); 
     } 
     try { 
      StringBuilder sb = new StringBuilder(); 
      BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream())); 
      String line; 
      while ((line = br.readLine()) != null) { 
       sb.append(line); 
       sb.append("\n"); 
      } 
      run.setText(sb.toString()); 
     } catch (IOException e) { 
      System.err.println("Error: " + e); 
     } 

     closeButton.addActionListener(new ActionListener() { 
      public void actionPerformed(ActionEvent c) { 
       runFrame.dispose(); 
      } 
     }); 

     somethingButton.addActionListener(new ActionListener() { 
      public void actionPerformed(ActionEvent c) { 
       //CODE TO STOP HERE 
      } 
     }); 
    } 
});
