Printing no of Process running in a table format

To find the number of processes running in a machine and print those in table format

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

public class NoofProcess {
  public static void main(String[] args) {
    try {
      // Process p = Runtime.getRuntime().exec("cmd /c tasklist /v");
      Process p = Runtime.getRuntime().exec("tasklist.exe /nh /v");
      BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
      String input, output = "";
      while ((input = stdInput.readLine()) != null) {
        output += input;
        System.out.println(input);
      }

      stdInput.close();
    } catch (Exception k) {
      k.printStackTrace();
    }
