Learn arrays in Java – the simplest way to store multiple values of the same type! This tutorial covers declaration, initialization, and common operations with practical examples.

📌 What is an Array?
A fixed-size collection of elements of the same data type, stored in contiguous memory.

Key Properties:
✔ Indexed access (starts at 0).
✔ Fixed length (set at creation).
✔ Supports primitives & objects.

💡 Key Notes
✔ Default Values:

0 for numbers, false for boolean, null for objects.
✔ Bounds Checking:

Accessing arr[10] in a size-5 array throws ArrayIndexOutOfBoundsException.

🚀 Real-World Uses
✔ Store user inputs (e.g., quiz scores).
✔ Group related data (e.g., product prices).
✔ Temporary data storage before processing.
