Java Arrays Made Easy: How to Use Arrays for Efficient Data Handling | Quick Tutorial

Arrays in Java are fixed-size, ordered collections of elements of the same type. They are used to store multiple values in a single variable, making them useful for organizing and processing data. Arrays are simple and efficient, but their size cannot be changed after creation.

Declare an array by specifying the type of its elements, followed by square brackets.
Initialize the array by assigning it a new array object with a specified length, or by directly listing the elements inside curly braces.
Access array elements using their index, which starts from 0.

In this example, we declare and initialize an array of integers, access and print its elements, and modify an element by assigning a new value to it using its index.
