How to Execute Windows Commands Using Java - Change Network Settings

Question

In Java, I want to be able to execute a Windows command.

The command in question is netsh. This will enable me to set/reset my IP address.

Note that I do not want to execute a batch file.

Instead of using a batch file, I want to execute such commands directly. Is this possible?

Here is my implemented Solution for Future Reference:

public class JavaRunCommand {     private static final String CMD =          "netsh int ip set address name = \"Local Area Connection\" source = static addr = 192.168.222.3 mask = 255.255.255.0";     public static void main(String args[]) {          try {             // Run "netsh" Windows command             Process process = Runtime.getRuntime().exec(CMD);              // Get input streams             BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream()));             BufferedReader stdError = new BufferedReader(new InputStreamReader(process.getErrorStream()));              // Read command standard output             String s;             System.out.println("Standard output: ");             while ((s = stdInput.readLine()) != null) {                 System.out.println(s);             }              // Read command errors             System.out.println("Standard error: ");             while ((s = stdError.readLine()) != null) {                 System.out.println(s);             }         } catch (Exception e) {             e.printStackTrace(System.err);         }     } } 

Answer 1

Runtime.getRuntime().exec("netsh"); 

See Runtime Javadoc.

EDIT: A later answer by leet suggests that this process is now deprecated. However, as per the comment by DJViking, this appears not to be the case: Java 8 documentation. The method is not deprecated.

Answer 2

Use ProcessBuilder

ProcessBuilder pb=new ProcessBuilder(command); pb.redirectErrorStream(true); Process process=pb.start(); BufferedReader inStreamReader = new BufferedReader(     new InputStreamReader(process.getInputStream()));   while(inStreamReader.readLine() != null){     //do something with commandline output. }
