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 characterstics 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:
// 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:
br>
[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:
// 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:
// 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:
// 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:
// 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:
// 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:
// 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:
// 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
