從java程序運行MS-DOS命令

Question

如何在我的java程序中運行MS-DOS命令？

Answer 1

How to run command-line or execute external application from Java：

import java.io.*; 

public class Main { 

     public static void main(String args[]) { 

      try { 
       Runtime rt = Runtime.getRuntime(); 
       //Process pr = rt.exec("cmd /c dir"); 
       Process pr = rt.exec("c:\\helloworld.exe"); 

       BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream())); 

       String line=null; 

       while((line=input.readLine()) != null) { 
        System.out.println(line); 
       } 

       int exitVal = pr.waitFor(); 
       System.out.println("Exited with error code "+exitVal); 

      } catch(Exception e) { 
       System.out.println(e.toString()); 
       e.printStackTrace(); 
      } 
     } 
} 

Answer 2

使用Runtime.getRuntime().exec()

Answer 3

Process p = Runtime.getRuntime().exec("cmd /C dir"); 
BufferedReader stdin = new BufferedReader(new InputStreamReader(p.getInputStream())); 

Answer 4

使用ProcessBuilder如。

Process p = new ProcessBuilder("myCommand", "myArg").start();

這在Java5的補充，它取代Runtime.getRuntime().exec()
