    A tuple is a data structure that can hold a fixed number of elements of different types. Tuples are immutable, meaning once they are created, their values cannot be changed. They are useful for grouping multiple values together without creating a separate class for each combination of values.

    Creating Tuples

    In Java, tuples are not part of the standard library, but you can use the Javatuples library to work with tuples. This library provides classes for tuples of different sizes, from a single element (Unit) to ten elements (Decade). To use Javatuples, you need to add the following Maven dependency to your pom.xml file:

    <dependency>
    <groupId>org.javatuples</groupId>
    <artifactId>javatuples</artifactId>
    <version>1.2</version>
    </dependency>

    Example of Creating Tuples

    You can create tuples using the with() method or constructors provided by the Javatuples library. Here are some examples:

    import org.javatuples.Pair;
    import org.javatuples.Triplet;
    import org.javatuples.Quartet;

    public class TupleExample {
    public static void main(String[] args) {
    // Creating a Pair
    Pair<String, Integer> pair = Pair.with("A pair", 55);

    // Creating a Triplet
    Triplet<String, Integer, Double> triplet = Triplet.with("hello", 23, 1.2);

    // Creating a Quartet
    Quartet<String, Double, Integer, String> quartet = Quartet.with("john", 72.5, 32, "1051 SW");

    // Printing the tuples
    System.out.println(pair);
    System.out.println(triplet);
    System.out.println(quartet);
    }
    }
    What is the difference between a tuple and an array?
    Lists are designed to store elements of a single type. Out of all data structures, a tuple is considered to be the fastest, and they consume the least amount of memory. While array and list are mutable which means you can change their data value and modify their structures, a tuple is immutable.

    Technically speaking, a tuple is like a small and immutablewrapper object that holds different pieces of information.
