In Java, an array is a data structure that allows you to store multiple values of the same type. It is a fixed-size container that can hold a specific number of elements. Here is how you can declare and initialize an array in Java: // Declaring an array of integers int[] numbers; // Initializing the array with values numbers = new int[]{1, 2, 3, 4, 5}; // Accessing elements of the array int firstNumber = numbers[0]; // 1 int secondNumber = numbers[1]; // 2 You can also declare and initialize an array in a single line: int[] numbers = {1, 2, 3, 4, 5}; To get the length of an array, you can use the `length` property: int length = numbers.length; // 5 You can iterate over the elements of an array using a for loop: for (int i = 0; i Arrays can also store objects of a class. For example, you can create an array of strings: String[] names = {"John", "Jane", "Alice"}; Arrays are zero-indexed, meaning the first element is at index 0. If you try to access an element outside the bounds of the array, you will get an `ArrayIndexOutOfBoundsException` error. Arrays have a fixed size, which means you cannot add or remove elements once the array is created. If you need a dynamic-size container, you can use the `ArrayList` class from the `java.util` package.
