The
ObjLongConsumer Interface is a part of the
java.util.function package which has been introduced since Java 8, to implement
functional programming in Java. It represents a function which takes in two arguments and produces a result. However these kind of functions don't return any value.
Hence this functional interface takes in one generic namely:-
- T: denotes the type of the input argument to the operation
The lambda expression assigned to an object of ObjLongConsumer type is used to define its
accept() which eventually applies the given operation on its argument. It takes in a long-valued and a T-valued argument and is expected to operate without any side effects. It is more like using an object of type
BiConsumer<T, Long> except the fact that one is a reference and one is a primitive data type in this case. Hence we will be obtaining one reference and one value when this function is called.
Functions in ObjLongConsumer Interface
The ObjLongConsumer interface consists of the following two functions:
1. accept()
This method accepts two values and performs the operation on the given arguments.
Syntax:
void accept(T t, long value)
Parameters: This method takes in two parameters:
- t- the first input argument
- value- the second input argument
Return Value: This method does not return any value.
Below is the code to illustrate accept() method:
