    In Java, the length() method of the String class is used to get the number of characters in a string, including spaces. It returns an int value representing the length.

    Example:

    public class Main {
    public static void main(String[] args) {
    String txt = "Hello";
    System.out.println(txt.length()); // Output: 5
    }
    }
    Gekopieerd.

    Here, "Hello" contains 5 characters, so txt.length() returns 5.

    How it works:

    • The length() method is called on a String object using the dot (.) operator.

    • It counts all characters, including spaces and special symbols.

    • The return type is int, so you can store it in an integer variable if needed.

    Another Example with Spaces and Special Characters:

    public class Main {
    public static void main(String[] args) {
    String txt = "Java Rocks! šŸš€";
    int len = txt.length();
    System.out.println("Length: " + len); // Output: 13
    }
    }
    Gekopieerd.

    Here, spaces and the emoji are counted as characters, so the total length is 13.

    Key Points to Remember:

    • Works for String, StringBuilder, and StringBuffer objects.

    • For arrays in Java, use .length (without parentheses), but for strings, always use .length() (with parentheses).

    • An empty string ("") has a length of 0.

    What is length in Java?
    All things considered, Java's length () method is a basic tool for working with strings that lets programmers precisely determine how big textual data is in their applications. Length of characters. In other words, the total number of characters present in the string. All characters are included in this count, regardless of their encoding or type.
