Tutorial: Using Arrays in Java

Arrays in Java are a fundamental structure that allows you to store a fixed number of elements of the same type. Arrays are useful for handling collections of data and performing repetitive tasks on them. In this tutorial, we'll cover the basics of declaring, initializing, and using arrays in Java.

1. Declaring an Array
To declare an array in Java, you specify the type of elements the array will hold, followed by square brackets [] and the array name. This does not yet create the array; it simply defines the variable.
2. Initializing an Array
After declaring an array, you need to initialize it by allocating memory. The syntax is as follows:
3. Adding Elements to an Array
Once an array is initialized, you can add elements to it by specifying the index (position) in square brackets. Array indices in Java start from 0, so the first element is at index 0, the second element at index 1, and so on.
4. Accessing Elements in an Array
You access elements by their index:
