    Arrays in Java are a fundamental data structure that allows you to store multiple values of the same type in a single variable. They are useful for managing collections of data efficiently. Arrays in Java are different from arrays in C/C++ as they are dynamically allocated and can store both primitive types and objects.

    Declaring and Initializing Arrays

    To declare an array in Java, you use the following syntax:

    dataType[] arrayName;
    הועתק!

    For example, to declare an array of integers:

    int[] numbers;
    הועתק!

    To create and initialize an array, you use the new keyword:

    numbers = new int[5]; // Creates an array of 5 integers
    הועתק!

    You can also declare and initialize an array in a single line:

    int[] numbers = {10, 20, 30, 40, 50};
    הועתק!

    Accessing and Modifying Array Elements

    Array elements are accessed using their index, which starts from 0. For example:

    int firstElement = numbers[0]; // Accesses the first element
    numbers[0] = 15; // Modifies the first element
    הועתק!

    To get the length of an array, you use the length property:
