RPG Inventory System (JavaBasics_Task_169_V0.1)

📖 Description

This project demonstrates the ArrayIndexOutOfBoundsException in Java. It simulates an RPG inventory where a player attempts to access an item slot that does not exist. This helps in understanding how to handle errors when working with fixed-size data structures like arrays.

📋 Requirements Compliance

• Task: Create an inventory array with 3 slots and attempt to access the 10th index.
• Variable: int[] heroInventory with IDs 101, 102, 103.
• Mechanism: try-catch block for ArrayIndexOutOfBoundsException.
• Goal: Catch the error and display a user-friendly warning message.

🚀 Architectural Stack

• Java 8+

🏗️ Implementation Details

In Java, arrays have a fixed length. Attempting to access an index that is less than 0 or greater than or equal to the array's length triggers an ArrayIndexOutOfBoundsException. By using exception handling, we can prevent the game from crashing and notify the user about the invalid input.

📋 Expected result

Error! This slot does not exist in the backpack. Index out of bounds.

💻 Code Example

Project Structure:

Code

package com.yurii.pavlenko;

public class Solution {
    public static void main(String[] args) {

        int[] heroInventory = {101, 102, 103};

        try {
            int item = heroInventory[10];
            System.out.println("Item found: " + item);

        } catch (ArrayIndexOutOfBoundsException e) {
            System.out.println("Error! This slot does not exist in the backpack. Index out of bounds.");
        }
    }
}
