    A character array in Java is a sequence of char elements stored in contiguous memory locations. Unlike Strings, which are immutable, character arrays are mutable, allowing direct modification of individual characters.

    Declaration and Initialization You can declare a character array in multiple ways:

    char[] charArray; // Declaration only
    charArray = new char[5]; // Initialization with size
    char[] charArray2 = {'a', 'b', 'c'}; // Declaration + initialization
    Copied!

    By default, uninitialized elements are set to '\u0000' (null character).

    Accessing and Modifying Elements Elements are accessed via their index:

    charArray[0] = 'x';
    System.out.println(charArray[0]);
    Copied!

    Iterating Through a Char Array You can use a for loop or enhanced for loop:

    for (int i = 0; i < charArray.length; i++) {
    System.out.println(charArray[i]);
    }

    for (char c : charArray) {
    System.out.println(c);
    }
    Copied!

    Length of a Char Array

    System.out.println(charArray.length);
    Copied!
