Java Help Calculating The Balance

Hey guys i am in need of some desperate help with a program i'm trying to create. Basically it's a program that has 3 options. Selecting "A" will prompt the user for 3 values. An Initial Deposit Amount, Rate of interest per year and Amount to be deposited each month.

Once the user has supplied the initial deposit amount and interest rate for the account as well as the monthly deposit amount, the program should then proceed to calculate the new balance for the account including interest earned over a six month period.

So far i have the basic outline out and i have the 3 input values but for the 2nd value "Enter the annual interest rate as a percentage" i don't know how to code it to it says for example 6.0 instead of 60.

And how would i do the calculation for the initial deposit amount, monthly deposit amount and new balance for the account including interest? I'm new to java programming so i'm still a bit unsure. Any help would be greatly appreciated. Here is my program code,

import java.util.Scanner;

public class MenuDrivenProgram
{
    private static Scanner s = new Scanner(System.in);
   
    public static void main(String[] args)
    {
        String inputLine;
        char option = ' ';
       
        do
        {
            //Prints the line allowing you to select one of the valid options
            printMenu();
            System.out.printf("Please select a valid option: ");
            inputLine = s.nextLine();
           
            //Prints out an error message if length is equal to 1
            if (inputLine.length() != 1)
            {
                System.out.printf("Error! You did not select a valid option!\n");
                System.out.printf("Please try again\n\n");
            }
            else
            {
                option = inputLine.charAt(0);
                option = Character.toUpperCase(option);
               
                switch (option)
                {
                        //Brings up the InvestmentReport menu
                    case 'A':
                        InvestmentReport();
                        break;
                       
                        //Brings up the RainfallReport menu
                    case 'B':
                        RainfallReport();
                        break;
                       
                        //Exits the program with a goodbye message
                    case 'X':
                        System.out.printf("Exiting the program - goodbye...\n\n");
                        break;
                       
                        //Errors out if keyed in value isn't a valid menu option
                    default:

                                          option);
                       
                }
            }

For your first question, try this instead:

System.out.println ("Enter the annual interest rate as a percentage (eg. 6.0)\n");
interest = console.nextDouble();

Thankyou that worked perfectly.

Can anyone help me with calculating the balance though? I'm still unsure how i would work that out over 6 months

 

Also before i forget here is the formula! Can anyone help me with coding this so it displays the calculated balance over the 6 month period?

balance = balance + monthly deposit amount
interest = balance (current) * ((interest rate / 12) / 100)
balance (new) = balance (current) + interest

 

Interest rate / 2 maybe, instead of 12?
