Multiple nCr program

Okay, so I have to create a nCr program.

I need to allow the user to input the amount of nCr values they wish to calculate ( between 2 and 12 inclusive). Then input the n and r values accordingly, making sure n is greater than r (n > r) Afterwards i need to calculate and store the nCr value in an array and output the values

I wish to output the values in the format of a 2d array in the form of:

n | c | nCr

(without the grids)

So far my code is as follows:

    public class nCr {
     public static void main (String[] args) {
            int nCrValues;

            System.out.println("Enter amount of nCr values you wish to calculate: ");
            nCrValues = input();

            while ((nCrValues < 2) || (nCrValues > 10)){
              System.out.println("Must be between 2 and 12 inclusive");
              nCrValues = input();
            }//END while
           values(nCrValues);
              }//END main

         public static void values(int nCrValues){

             //I know I need a loop to nCrValues to input 'n' and 'r' as an array, not sure how

             int n, r;

             System.out.println("Enter n value: ");
             n = input();
             System.out.println("Enter r value: ");
             r = input();

             calculatenCr(n,r);
    }//END values

     public static int calculatenCr(int n, int r){
      int nCr;

      nCr = fact(n) / (fact(n-r) * fact(t));
      //store nCr values in array
    }//END calculatenCr

   public static int fact(int num){
      int count;
      int factor = 1;

      for (count = 1; count <= num; count++){
       factor *= count;
      }//END for
     return factor;
    }//END fact

     public static int input(){
      int input;

      Scanner sc = new Scanner(System.in);
      input = sc.nextInt();

       while (input < 0){
        System.out.println("Must be a positive number.")'
        input = sc.nextInt();
       }//END while
      return input;
     }//END input
}//END CLASS

I need a method that outputs the arrays int the form

n | c | nCr |

how do i go by that and is all my coding correct so far?

Thank you very much

Not fully understanding if you just want to print the number of combinations,not actual combinations themselves, but that's what your code indicates, so that's the way I completed it:

public class Ncr {
    public static void main (String[] args) {
        int nCrValues;

        System.out.println("Enter amount of nCr values you wish to calculate: ");
        nCrValues = input();

        while ((nCrValues < 2) || (nCrValues > 10)){
            System.out.println("Must be between 2 and 12 inclusive");
            nCrValues = input();
        }//END while
        for (int[] res : values(nCrValues)) {
            System.out.println(String.format("%d | %d | %d", res[0], res[1], res[2]));
        }
    }//END main

    public static int[][] values(int nCrValues){

        //I know I need a loop to nCrValues to input 'n' and 'r' as an array, not sure how
        int[][] res = new int[nCrValues][3];
        for (int i = 0; i < nCrValues; i++) {
            int n, r;

            System.out.println("Enter n value: ");
            n = input();
            System.out.println("Enter r value: ");
            r = input();

            res[i] = new int[]{n, r, calculatenCr(n, r)};
        }
        return res;
    }//END values

    public static int calculatenCr(int n, int r){
        return fact(n) / (fact(n-r) * fact(r));
    }//END calculatenCr

    public static int fact(int num){
        int count;
        int factor = 1;

        for (count = 1; count <= num; count++){
            factor *= count;
        }//END for
        return factor;
    }//END fact

    public static int input(){
        int input;

        Scanner sc = new Scanner(System.in);
        input = sc.nextInt();

        while (input < 0){
            System.out.println("Must be a positive number.");
            input = sc.nextInt();
        }//END while
        return input;
    }//END input
}//END CLASS
