the output of this method is the same output of the command variable if you typed in cmd because it create a cmd process and input the command variable then take the output and return it

CMD.java

import java.io.BufferedReader;
import java.io.InputStreamReader;

class CommandPrompt {

  public static void runSystemCommand(String command) {

		try {
			Process p = Runtime.getRuntime().exec(command);
			BufferedReader inputStream = new BufferedReader(
					new InputStreamReader(p.getInputStream()));

			String s = "";
			// reading output stream of the command
			while ((s = inputStream.readLine()) != null) {
				System.out.println(s);
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
