Trying to combine 2 programs into a single one

So I've got 2 Mains and I'm trying to combine them to run together and struggling. The 1st rolls a single die 6000 times and shows the results and the second rolls 2 dice 11000 times and shows the results. What is the easiest way to combine these so they run 1 and than the other. Programs as follows:

public class DieTest
{
   public static final int N = 6000;

   public static void main(String[] args)
   {
      int[] d = new int[7];
      for (int i = 1; i < 7; i++) d[i] = 0;

      for (int k = 0; k < N; k++)
      {
         int roll = (int)(6.0*Math.random() + 1.0);
         d[roll]++;
      }
      System.out.print("Rolls: " + N);
      for (int i = 1; i < 7; i++)
         System.out.print(", " + i + ": " + d[i]);
      System.out.println();
   }

}

and the second

public class Dice3
{
   public static final int N = 11000;

   public static int roll()
   {
      return (int)(6.0*Math.random() + 1.0);
   }

   public static void main(String[] args)
   {
      int[] d = new int[13];
      for (int i = 1; i < 13; i++) d[i] = 0;

      for (int k = 0; k < N; k++)
      {
         d[roll() + roll()]++;
      }
      System.out.print("Rolls: " + N);
      for (int i = 2; i < 13; i++)
         System.out.print(", " + i + ": " + d[i]);
      System.out.println();
   }
}

public class TwoDieFor
{
  public static void main(String ... arguments)
  {
    DieTest.main(arguments);
    Dice3.main(arguments);
  }
}

1.Create another class to combine the code.
2.Create 1 method for each of the 2 main() methods, of course with new names like roll1() and roll2() without parameters and paste inside them the code you already have.
3.Paste also the declarations of N from DieTest and Dice3 but rename the 2nd to M and change every occurrence of N to M in the 2nd method you created.
4.You need also to paste the method roll().
5.Create a new main() method like this: 

public static void main(String[] args) {
    roll1();
    roll2();
}
