    The split() method in Java is used to divide a string into an array of substrings based on a given regular expression (regex). It’s commonly used for parsing and processing text data efficiently.

    Example: Splitting by space

    public class Main {
    public static void main(String[] args) {
    String text = "Java is fun";
    String[] words = text.split(" ");
    for (String word : words) {
    System.out.println(word);
    }
    }
    }
    Copied!

    Output:

    Java
    is
    fun
    Copied!

    Basic Syntax

    public String[] split(String regex)
    public String[] split(String regex, int limit)
    Copied!

    • regex – The delimiter pattern (can be a string or regex).

    • limit – Controls the number of resulting substrings.

    Using split() without limit Splits at every match of the regex.

    String s = "a::b::c::d";
    String[] parts = s.split("::");
    System.out.println(Arrays.toString(parts));
    // Output: [a, b, c, d]
    Copied!

    Using split() with limit

    • limit > 0 → Splits at most limit - 1 times.

    • limit = 0 → Splits fully, removes trailing empty strings.

    • limit < 0 → Splits fully, keeps trailing empty strings.
