JavaTuples - Quintet Class

Introduction

The org.javatuples.Quintet class represents a Tuple with five elements.

Class Declaration

Following is the declaration for org.javatuples.Quintet class −

public final class Quintet<A, B, C, D, E>
   extends Tuple
      implements IValue0<A>, IValue1<B>, 
         IValue2<C>, IValue3<D>, IValue4<E>

Class Constructor

Sr.No. Constructor & Description
1

Quintet(A value0, B value1, C value2, D value3, E value4)

This creates a Quintet Tuple.

Class Methods

Similarly setAt1() upto setAt4() set the value at index 1, and so on.

Sr.No. Method & Description
1

Sextet add(Unit tuple)

This method returns a Sextet tuple.

Similarly other methods to add tuples are available e.g. add(Pair tuple) returns Septet and upto add(Quintet tuple) returns Decade tuple.
2

Sextet add(X0 value)

This method add a value to the tuple and returns a Sextet tuple.

Similarly other methods to add values are available e.g. add(X0 value0, X1 value1) returns Septet and so on upto add() with five parameters.
3

Sextet addAt0(Unit value)

This method add a Unit tuple at index 0 and returns a Sextet tuple.

Similarly other methods to add tuples are available e.g. addAt0(Pair value) returns Septet and so on upto addAt0(Quintet). Other similar method are addAt1(Unit value) which add a unit at index0 and have similar methods upto addAt4(Quintet).
4

Sextet addAt0(X0 value)

This method add a value at index 0 and returns a Sextet tuple.

Similarly other methods to add values are available e.g. addAt0(X0 value0, X1 value1) returns Septet and so on upto addAt0() with five parameters. Other similar method are addAt1(X0 value) which add a value at index0 and have similar methods upto addAt4() with five parameters.
5

static <X> Quintet<X,X,X,X,X> fromArray(X[] array)

Create tuple from array.
6

static <X> Quintet<X,X,X,X,X> fromCollection(Collection<X> collection)

Create tuple from collection.
7

static <X> Quintet<X,X,X,X,X> fromIterable(Iterable<X> iterable)

Create tuple from iterable.
8

static <X> Quintet<X,X,X,X,X> fromIterable(Iterable<X> iterable, int index)

Create tuple from iterable, starting from the specified index.
9

int getSize()

Return the size of the tuple.
10

A getValue0()

Returns the value of the tuple at index 0.

Similarly getValue1() upto getValue4() returns the value at index 1 and so on.
11

Quartet<B,C,D,E> removeFrom0()

Return the tuple after removing value of the tuple at index 0.

Similarly removeFrom1() upto removeFrom4() returns the tuple after removing value of the tuple at index 1 and so on.
12

<X> Quintet<X,B,C,D,E> setAt0(X value)

Set the value of the tuple at index 0.
13

static <A> Quintet<A,B,C,D,E> with(A value0, B value1, C value2, D value3, E value4)

Create the tuple using given value.

Methods inherite

This class inherits methods from the following classes −

  • org.javatuples.Tuple

  • Object

Example

Let's see Quintet Class in action. Here we'll see how to use various methods.

Create a java class file named TupleTester in C:\>JavaTuples.

File: TupleTester.java

package com.tutorialspoint;
import java.util.ArrayList;
import java.util.List;
import org.javatuples.Quartet;
import org.javatuples.Quintet;
import org.javatuples.Sextet;
import org.javatuples.Triplet;

public class TupleTester {
   public static void main(String args[]){
      Quintet<Integer, Integer, Integer, Integer, Integer> quintet 
         = Quintet.with(5, 6, 7,8,9);
      System.out.println(quintet);
      boolean isPresent = quintet.contains(5);
      System.out.println("5 is present: " + isPresent);
      List<Integer> list = new ArrayList<>();
      list.add(1);
      list.add(2);
      list.add(3);
      list.add(4);
      list.add(5);
      Sextet<Integer, Integer, Integer, Integer, Integer, String> sextet 
         = quintet.add("Test");
      System.out.println(sextet);
      Integer value = quintet.getValue0();
      System.out.println(value);
      Quartet<Integer, Integer, Integer, Integer> quartet = quintet.removeFrom0();
      System.out.println(quartet);
      Quintet<Integer, Integer, Integer, Integer, Integer> quintet1 
         = Quintet.fromCollection(list);   
      System.out.println(quintet1);
   }
}

Verify the result

Compile the classes using javac compiler as follows −

C:\JavaTuples>javac -cp javatuples-1.2.jar ./com/tutorialspoint/TupleTester.java

Now run the TupleTester to see the result −

C:\JavaTuples>java  -cp .;javatuples-1.2.jar com.tutorialspoint.TupleTester

Output

Verify the Output

[5, 6, 7, 8, 9]
5 is present: true
[5, 6, 7, 8, 9, Test]
5
[6, 7, 8, 9]
[1, 2, 3, 4, 5]
