How can I execute a dos command?

Question

I tryed so:
import java.io.BufferedReader;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintStream;
public class Builder {
     public static void main(String[]args)
               //makeFile();
               execute();
     * @author Savio
     * @description Esegue comando dos
     * @throws IOException
     public static void execute()
          try
               Runtime will = Runtime.getRuntime();
               Process pid=will.exec("cmd /c c:prova.bat");
               InputStreamReader isr = // step 3
                    new InputStreamReader( pid.getInputStream() );
                    BufferedReader br = new BufferedReader( // step 4.
                    isr );
                    String line;
                    while ((line = br.readLine()) != null)
                    System.out.println(line);
          catch (IOException e)
                         e.printStackTrace();
     * @author Savio
     * @description Crea e scrive un file
     * @throws IOException
     public static void makeFile() throws IOException
          FileOutputStream file=new FileOutputStream("c:/condor/bin/file.submit");
          PrintStream out=new PrintStream(file);
          out.println("### SUBMIT DESCRIPTION FILE ###");
          out.println("Universe = java");
          out.println("Executable = job.class");
          out.println("Jar_files = job.jar");
          //out.println("Arguments = "+args[0]+" "+args[1]+" "+args[2]+" "+args[3]);
          for (int i=0; i<10;i++)
               out.println("Output"+i+"txt");
               out.println("Error"+i+".txt");
               out.println("Log"+i+".log");
This doesn't works!!

Can you help me!!!

Please use code tags when posting code.
Use ProcessBuilder or Runtime.exec(String, String[])
