Septet Class in JavaTuples

  • Last Updated : 11 Aug, 2021
Geek Week

A Septet is a Tuple from JavaTuples library that deals with 3 elements. Since this Septet is a generic class, it can hold any type of value in it.
Since Septet is a Tuple, hence it also has all the characteristics of JavaTuples: 
 

  • They are Typesafe
  • They are Immutable
  • They are Iterable
  • They are Serializable
  • They are Comparable (implements Comparable<Tuple>)
  • They implement equals() and hashCode()
  • They also implement toString()

 

Class Declaration

 

public final class Septet<A, B, C, D, E, F, G> extends Tuple
implements IValue0<A>, IValue1<B>, IValue2<C>, IValue3<D>, IValue4<E>, IValue5<F, IValue6<G>

 

Class hierarchy

 



Object
  ↳ org.javatuples.Tuple
      ↳ org.javatuples.Septet<A, B, C, D, E, F, G>

 

Creating Septet Tuple

 

  • From Constructor:
    Syntax
     
Septet<A, B, C, D, E, F, G> septet = 
    new Septet<A, B, C, D, E, F, G>
        (value1, value2, value3, value4, value5, value6, value7);
  • Example
     

Java




// Below is a Java program to create
// a Septet tuple from Constructor
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        System.out.println(septet);
    }
}
  • Output: 
     
[1, 2, 3, 4, 5, 6, 7]
  •  
  • Using with() method: The with() method is a function provided by the JavaTuples library, to instantiate the object with such values.
    Syntax
     
Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    Septet.with(value1, value2, value3, value4, value5, value6, value7);
  • Example
     

Java




// Below is a Java program to create
// a Septet tuple from with() method
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        System.out.println(septet);
    }
}
  • Output: 
     
[1, 2, 3, 4, 5, 6, 7]
  •  
  • From other collections: The fromCollection() method is used to create a Tuple from a collection, and fromArray() method is used to create from an array. The collection/array must have the same type as of the Tuple and the number of values in the collection/array must match the Tuple class.
    Syntax
     
Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    Septet.fromCollection(collectionWith_7_value);

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    Septet.fromArray(arrayWith_7_value);
  • Example
     

Java




// Below is a Java program to create
// a Septet tuple from Collection
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        // Creating Septet from List
        List<Integer> list = new ArrayList<Integer>();
        list.add(1);
        list.add(2);
        list.add(3);
        list.add(4);
        list.add(5);
        list.add(6);
        list.add(7);
 
        Septet<Integer, Integer, Integer, Integer, Integer, Integer> septet
            = Septet.fromCollection(list);
 
        // Creating Septet from Array
        Integer[] arr = { 1, 2, 3, 4, 5, 6, 7 };
 
        Septet<Integer, Integer, Integer, Integer, Integer, Integer> otherSeptet
            = Septet.fromArray(arr);
 
        System.out.println(septet);
        System.out.println(otherSeptet);
    }
}
  • Output: 
     
[1, 2, 3, 4, 5, 6, 7]
[1, 2, 3, 4, 5, 6, 7]
  •  

 

Getting value

The getValueX() method can be used to fetch the value in a Tuple at index X. The indexing in Tuples start with 0. Hence the value at index X represents the value at position X+1.
Syntax
 

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    new Septet<type1, type2, type3, type4, type5, type6, type7>
        (value1, value2, value3, value4, value5, value6, value7);

type1 val1 = septet.getValue0();

Example
 



Java




// Below is a Java program to get
// a Septet value
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        System.out.println(septet.getValue0());
        System.out.println(septet.getValue2());
    }
}

Output: 
 

1
3

 

Setting Septet Value

Since the Tuples are immutable, it means that modifying a value at any index is not possible. Hence JavaTuples offer setAtX(value) which creates a copy of the Tuple with a new value at index X, and returns that Tuple.
Syntax
 

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    new Septet<type1, type2, type3, type4, type5, type6, type7>
                (value1, value2, value3, value4, value5, value6, value7);

Septet<type1, type2, type3, type4, type5, type6, type7> 
    otherSeptet = septet.setAtX(value);

Example
 

Java




// Below is a Java program to set
// a Septet value
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> otherSeptet
            = septet.setAt3(40);
 
        System.out.println(otherSeptet);
    }
}

Output: 
 

[1, 2, 3, 40, 5, 6, 7]

 

Adding a Value

Adding a value can be done with the help of addAtX() method, where X represent the index at which the value is to be added. This method returns a Tuple of element one more than the called Tuple.
Syntax
 

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    new Septet<type1, type2, type3, type4, type5, type6, type7>
        (value1, value2, value3, value4, value5, value6, value7);

Septet<type 1, type 2, type 3, type 4, type 5, type 6, type 7> septet = 
    septet.addAtx(value);

Example
 



Java




// Below is a Java program to add
// a value
 
import java.util.*;
import org.javatuples.Septet;
import org.javatuples.Octet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        Octet<Integer, Integer, Integer.Integer, Integer, Integer, Integer, Integer> octet
            = septet.addAt7(8);
 
        System.out.println(octet);
    }
}

Output: 
 

[1, 2, 3, 4, 5, 6, 7, 8]

 

Searching in Septet

An element can be searched in a tuple with the pre-defined method contains(). It returns a boolean value whether the value is present or not.
Syntax
 

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    new Septet<type1, type2, type3, type4, type5, type6, type7>
        (value1, value2, value3, value4, value5, value6, value7);

boolean res = septet.contains(value2);

Example
 

Java




// Below is a Java program to search
// a value in a Septet
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        boolean exist = septet.contains(5);
        boolean exist1 = septet.contains(false);
 
        System.out.println(exist);
        System.out.println(exist1);
    }
}

Output: 
 

true
false

 

Iterating through Septet

Since Septet implement the Iterable<Object> interface. It means that they can be iterated in the same way as collections or arrays.
Syntax
 

Septet<type1, type2, type3, type4, type5, type6, type7> septet = 
    new Septet<type1, type2, type3, type4, type5, type6, type7>
            (value1, value2, value3, value4, value5, value6, value7);

for (Object item : septet) {
        ...
}

Example
 

Java




// Below is a Java program to iterate
// a Septet
 
import java.util.*;
import org.javatuples.Septet;
 
class GfG {
    public static void main(String[] args)
    {
        Septet<Integer, Integer.Integer, Integer, Integer, Integer, Integer> septet
            = Septet.with(Integer.valueOf(1),
                          Integer.valueOf(2),
                          Integer.valueOf(3),
                          Integer.valueOf(4),
                          Integer.valueOf(5),
                          Integer.valueOf(6),
                          Integer.valueOf(7));
 
        for (Object item : septet)
            System.out.println(item);
    }
}

Output: 
 

1
2
3
4
5
6
7
