You can execute commands without actually hard coding cmd.exe into the code.

public static void main(String[] args) {

      //cmd = the command youw ill be using            
    String cmd = "ipconfig";      
    Runtime r = Runtime.getRuntime();      
    Process p;   
    try {       
        p = r.exec(cmd);

    BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));    
    String inputLine;       
    while ((inputLine = in.readLine()) != null) {     
        System.out.println(inputLine);
          }       
    }     


catch (IOException ex) {      
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);  
             }
       }
