Gem Collector Inventory (JavaBasics_Task_165_V0.1)

📖 Description

This project explores how Java manages memory and array boundaries. In many programming languages, accessing an index outside an array's range might return garbage data, but Java's strict type safety and runtime checks prevent this by throwing a specific exception.

📋 Requirements Compliance

• Task: Create an array of size 3 and attempt to access index 5.
• Array Content: [10, 20, 30].
• Goal: Observe the ArrayIndexOutOfBoundsException.

🚀 Architectural Stack

• Java 8+

🏗️ Implementation Details

Arrays in Java are objects with a fixed length attribute. When you attempt to access an element, the JVM checks if 0 <= index < length. If this condition is false, execution stops immediately. This is a crucial safety feature to prevent memory corruption and unauthorized data access.

📋 Expected result

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 3

💻 Code Example

Project Structure:

src/com/yurii/pavlenko/
                └── Solution.java

Code

package com.yurii.pavlenko;

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

        int[] collectedGems = new int[3];

        collectedGems[0] = 10;
        collectedGems[1] = 20;
        collectedGems[2] = 30;

        System.out.println("Searching for the hidden gem: " + collectedGems[5]);

        // This line will never be executed
        System.out.println("Search successful!");
    }
}
