The addAtX() method in org.javatuples is used to add a value to the existing tuple, at an index X. Since JavaTuples are immutable, hence adding a value to the existing tuple results in a new tuple with one more value. For example, adding a value to Unit tuple results in the formation of a Pair tuple. This method can be used for any tuple class object of the javatuples library, except the Decade class, as Decade is the highest class available in JavaTuples library. It returns the tuple class object of a class higher than the called class, decided by the number of values in the arguments.
Triplet<String, Integer, Double> triplet = ... ... Quartet<String, Integer, Double, type(s)> quartet = triplet.addAtX(value(s));
Parameters: This method can take n values as parameters where:
- X– represents the index at which the values are to be added.
- n– represents the number of values based on the TupleClass (Unit, Pair, etc) to be created as return object.
- type– represents the type for value(s) passed as arguments.
- value– represents the value(s) passed as arguments.
Return Value: This method returns the object of TupleClass with combined values of the called tuple class and the values passed as the parameters. The values passed are added at index X in the called tuple class values.
Below programs illustrate the various ways to use addAtX() methods:
Program 1: When the addAtX() method is used with any class from Unit to Ennead, with a direct values as parameter:
Program 2: When the addAtX() method is used with any class from Unit to Ennead, with a another tuple class object as parameter:
Note: Similarly, it can be used with any other JavaTuple Class.
