Java method that invokes the DOS command for Windows

This is an instance of using Java code to call DOS command, here I won't say much, directly on the code, the code is as follows:

import java.io.*;

/**

 *  Java call windows the DOS The command 

 *   To call Windows the ipconfig Command and then pass the output information through IO Stream output to the console. 

 */

public class RunWindowsCommand{

    public static void main(String[] args) {

        InputStream ins = null;

        String[] cmd = new String[] { "cmd.exe", "/C", "ipconfig" };  //The command < br / >
        try {

            Process process = Runtime.getRuntime().exec(cmd);

            ins = process.getInputStream();  //Gets the information after executing the CMD command 

            BufferedReader reader = new BufferedReader(new InputStreamReader(ins));   

            String line = null;   

            while ((line = reader.readLine()) != null) {   

                System.out.println(line);  //O < br / >
            } 

            int exitValue = process.waitFor();   

            System.out.println(" The return value: " + exitValue);  

            process.getOutputStream().close();  //Don't forget to close 

        } catch (Exception e) {

            e.printStackTrace();

        } 

    }

}
