Java - How to add numbers over time?

Question

<pre> import java.util.*;

public class Test {
private static int StartingMoney = 1000;
private static int MaxMoney = 10000;
private static int Add = 100;
static Scanner question = new Scanner(System.in);
    public static void main(String[] args) {
        while(StartingMoney != MaxMoney){
            System.out.println("1:Add Money");
            int userInput = question.nextInt();
                if(userInput == 1){
                    System.out.println(StartingMoney + Add);
                }

        }
    }

}

The goal of this code is to add a number until it reaches a certain amount, and the user will be able to choose whether or not he or she can add numbers to their current amount they have. The output is always 1100

Answer 1

By doing System.out.println(StartingMoney + Add); you are only printing the value to the console and not changing your actual StartingMoney variable and this will still be 1000.

Your program will go in an infinite loop as the condition StartingMoney != MaxMoney will never be reached.

You should be doing this instead:

StartingMoney += Add;
System.out.println(StartingMoney);

Here is the corrected code snippet:

import java.util.*;

public class Test {
    private static int StartingMoney = 1000;
    private static int MaxMoney = 10000;
    private static int Add = 100;
    private static Scanner question = new Scanner(System.in);

    public static void main(String[] args) {
        while(StartingMoney != MaxMoney){
            System.out.println("1: Add Money");
            int userInput = question.nextInt();
            if(userInput == 1) {
                /* Note the change here */
                StartingMoney += Add;
                System.out.println(StartingMoney);
            }
        }
    }
}
