Decade Class in JavaTuples

A Decade is a Tuple from JavaTuples library that deals with 3 elements. Since this Decade is a generic class, it can hold any type of value in it.

Since Decade 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 Decade<A, B, C, D, E, F, G, H, I, J>
extends Tuple
implements IValue0<A>, IValue1<B>, IValue2<C>, IValue3<D>, IValue4<E>, 
           IValue5<F, IValue6<G, IValue7<H>, IValue8<I, J>

Class hierarchy

Object
  ↳ org.javatuples.Tuple
      ↳ org.javatuples.Decade<A, B, C, D, E, F, G, H, I, J>

• From Constructor:

  Syntax:

  Decade<A, B, C, D, E, F, G, H, I, J> decade = 
      new Decade<A, B, C, D, E, F, G, H, I, J>
          (value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

  Output:

  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  

• Using with() method: The with() method is a function provided by the JavaTuples library, to instantiate the object with such values.

  Syntax:

  Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
      Decade.with(value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

  filter_none

  Output:

  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  

• 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:

  Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
      Decade.fromCollection(collectionWith_10_value);
  
  Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
      Decade.fromArray(arrayWith_10_value);

  filter_none

  Output:

  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  

Getting value

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

Syntax:

Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
    new Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9>
        (value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

type1 val1 = decade.getValue0();

Example:

Output:

1
3

Setting Decade 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:

Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
    new Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9>
                (value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> 
    otherDecade = decade.setAtX(value);

Example:

Output:

[1, 2, 3, 40, 5, 6, 7, 8, 9, 10]

Adding a value

JavaTuples do not support Tuple with more than 10 values. Hence there is no function to add a value in Decade.

Searching in Decade

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:

Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
    new Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9>
        (value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

boolean res = decade.contains(value2);

Example:

Output:

true
false

Iterating through Decade

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

Syntax:

Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9> decade = 
    new Decade<type1, type2, type3, type4, type5, type6, type7, type8, type9>
            (value1, value2, value3, value4, value5, value6, value7, value8, value9, value10);

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

Example:

Output:

1
2
3
4
5
6
7
8
9
10
