Hi, The Following Java Code To Add, Subtract, Multiply And Divide Two Numbers Correctly And Print Out Result. I Want It To Return To Where The User Will Choose Operands.

import java.util.Scanner;
public class Calculate
{
    public static void main(String[] args)
    {
        int firstNumber,secondNumber,operand;
        Scanner input=new Scanner(System.in);

        //create scanner object to object input from keyboard
        //System.out.println("Pls enter ur choice between 1 to 4 below");
        System.out.println("Enter number between 1 to 4 to choose operand");
        System.out.println("1. ADDITION");
        System.out.println("2. SUBTRACTION");
        System.out.println("3. MULTIPLICATION");
        System.out.println("4. DIVISON");
        operand=input.nextInt();
        System.out.print("Enter the first number:");
        firstNumber=input.nextInt(); //read the first number(firstNumber)
        System.out.print("Enter the second number:");
        secondNumber=input.nextInt();//read the second number(secondNumber)

        switch(operand)
        {
            case 1:
                System.out.println("The sum is = "+(firstNumber+secondNumber));
                break;
            case 2:
                System.out.println("The answer is ="+(firstNumber-secondNumber));
                break;
            case 3:
                System.out.println("The product is ="+(firstNumber*secondNumber));
                break;
            case 4:
                System.out.println("The answer is ="+(firstNumber/secondNumber));
                break;
            default:


        }

    }
}
