Hello,Below mentioned is my effort which works when the user enters 3 as the number wanted and 2 as the number that needs to be inserted.

public class Loop {

    public static void main(String[] args) {

        ArrayList array = new ArrayList();
        int[] br = new int[10];
        int i=0;
        Scanner scanner = new Scanner(System.in);
        System.out.println("enter the number you wanted ");
        int input_val = scanner.nextInt();
        System.out.println("Please choose the number below the given range");
        int chosen_num = scanner.nextInt();
        if (chosen_num <= input_val) {
            System.out.println("proceed");
            switch (chosen_num) {
                case 1:
                    //array.add(0,chosen_num);
                    //array.add(1*chosen_num+1,chosen_num);
                    br[i] = chosen_num;
                    br[chosen_num + 1] = chosen_num;

                    break;
                case 2:
                    br[i] = chosen_num;
                    br[chosen_num + 1] = chosen_num;
                    br[chosen_num-1]=chosen_num+1;
                    br[chosen_num]=chosen_num-1;
                    br[chosen_num*chosen_num]=chosen_num-1;
                    break;
              //  case 3:
                //    br[0] = chosen_num;
                  //  for()
                    //br[chosen_num + 1] = chosen_num;
                    //br[chosen_num]
                   // break;
                default:
                    System.out.println("invalid month");
                    break;

            }

        } else {
            System.out.println("please enter a valid statement");
        }


        for(i=0;i<br.length;i++)
        {
            System.out.println(br[i]);
        }

    }
        }
