Implement Quintet Class with Quartet Class in Java using JavaTuples
For implementing a quintet class in Java with JavaTuples, it's necessary to extend the quartet class and add one more element. JavaTuples offers a standardized API and a handy way to manage tuples of different lengths. Quintet is an extension of Quartet, which provides type safety and readability in tuple operations. It inherits its capability for handling a fixed-size tuple with four members while permitting the addition of a fifth.
Here are some examples of methods used to combine the Quartet Class with the Quintet Class.
- By using direct values
- By using Quartet.add() method
- By using Quartet.addAtX() method
Approach: By using direct values
The direct values function in javatuples shows how to generate and modify Quartet and Quintet tuples using the JavaTuples package. It starts with the creation of a quartet made up of four strings. Then, it joins the Quartet with a fifth string to create a Quintet. Lastly, it shows the tuples for the Quartet and Quintet. This demonstrates how type safety is maintained while allowing for simple handling of tuples of different sizes with the help of JavaTuples.
Implementation:
FileName: QuintetClass.java
import java.util.*; import java.io.*; import org.javatuples.*; public class QuintetClass { public static void main(String[] args) { //Creating the Quartet Quartetq = new Quartet ( "Hello", "Welcome", "To", "World"); // displaying the Quartet System.out.println("The Quartet is: " + q); // Creating the Quintet from the Quartet Quintet quin = new Quintet ( "Quintet 1", q.getValue0(), q.getValue1(), q.getValue2(), q.getValue3()); // displaying the Quintet System.out.println("The Quintet is: " + quin); } }
Output:
The Quartet is: [Hello, Welcome, To, World] The Quintet is: [Quintet 1, Hello, Welcome, To, World]
Approach: By using Quartet.add() method
The Quintet.The Add() function shows how to add an extra member to a Quartet, so forming a Quintet, using JavaTuples. First, a four-string quartet is composed and performed. The Quartet is then expanded to a Quintet by adding a fifth string using the add method. Upon displaying the final Quintet, JavaTuples' ease of use and adaptability in handling tuples of different lengths are demonstrated.
Implementation:
FileName: QuintetClassQuartetAdd.java
import java.util.*; import java.io.*; import org.javatuples.*; public class QuintetClassQuartetAdd { public static void main(String[] args) { //Creating the Quartet Quartetq = new Quartet ( "Hello", "Welcome", "To", "World"); // displaying the Quartet System.out.println("The Quartet is: " + q); // Create the Quintet from the Quartet Quintet quin = q.add("Quintet"); // displaying the Quintet System.out.println("The Quintet is: " + quin); } }
Output:
The Quartet is: [Hello, Welcome, To, World] The Quintet is: [Hello, Welcome, To, World, Quintet]
Approach: By using Quartet.addAtX() method
The Quartet and Quintet classes from the org.javatuples package are used to illustrate how to use them, and the AddAtX() function defines a class called QuintetAddAtX. The four strings ("Hello", "Welcome", "To", and "World") that make up a Quartet are created, printed, and then a new string called "Quintet" is added at the 0th index to change the Quartet into a Quintet. Finally, it releases the updated Quintet as well as the original Quartet. This illustrates the use of the Quartet class's addAt0 method, which adds elements at a specified index.
Implementation:
FileName: QuintetAddAtX.java
import java.io.*; import java.util.*; import org.javatuples.*; public class QuintetAddAtX { public static void main(String[] args) { //Creating the Quartet Quartetq = new Quartet ( "Hello", "Welcome", "To", "World"); // displaying the Quartet System.out.println("The Quartet is: " + q); // Creating the Quintet from the Quartet Quintet quin = q.addAt0("Quintet"); // displaying the Quintet System.out.println("The Quintet is: " + quin); } }
Output:
The Quartet is: (Hello, Welcome, To, World)
The Quintet is: (Quintet, Hello, Welcome, To, World)
