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.
