Would someone be willing to explain what I'm missing?

Question about the task

Resolved

As far as I can tell, I'm either out of my mind, or this is fishy. My program displays text on the screen. ✅ The addPrice method does NOT display text on the screen. ✅ The applePrice variable is static and initialized to zero. ✅ addPrice is only being called twice. ✅ The cost increases the cost of apples by the passed-in value. ✅ CodeGym says I'm failing. ✅ Please help. <3

Calculate the total cost of apples.
The total cost of apples corresponds to public static int applePrice.

Requirements:

The program should display text on the screen.
The Apple class's addPrice method should not display text on the screen.
The Apple class's applePrice variable must be a static int initialized to zero.
The main method should call the addPrice method only twice.
The Apple class's addPrice method should increase the cost of apples by the passed-in value.

package en.codegym.task.jdk13.task04.task0402; /* Price of apples */ public class Solution { public static void main(String[] args) { Apple apple = new Apple(); apple.addPrice(50); Apple apple2 = new Apple(); apple2.addPrice(100); System.out.println("Apple price " + Apple.applePrice); } public static class Apple { public static int applePrice = 0; public void addPrice(int applePrice) { applePrice = Apple.applePrice + applePrice; } } }

public static int applePrice = 0; /* 1 */

public void addPrice(int applePrice /* 2 */) {
    applePrice                                 =  Apple.applePrice    +     applePrice;
    // references the method parameter 2          references 1              references 2
}

In the end it should print

Apple price 150

because it is wrong. The method parameter is valid only inside the addPrice method. If you assign that parameter a value, then you can not access it later on anymore. When leaving the method that value is lost. What you need to do is to assign the value to the static variable (I marked it with a 1)

Apple.applePrice += applePrice;
