What is the ObjDoubleConsumer functional interface in Java?
ObjDoubleConsumer is a functional interface that expects an object-valued and a double-valued argument as input and produces no output. The interface contains one method, accept.
The ObjDoubleConsumer interface is defined in the java.util.function package. To import the ObjDoubleConsumer interface, use the following import statement.
import java.util.function.ObjDoubleConsumer;
The accept method
accept is the functional method of the interface that accepts an object and a double input and performs the given operation on the inputs without returning any result.
Syntax
void accept(T t, double value)
Parameters
T t: The first object argument.double value: Thedoubleinput argument.
Return value
The accept method doesn’t return a result.
Code
import java.util.function.ObjDoubleConsumer;public class Main{public static void main(String[] args) {// Implementation of ObjDoubleConsumerObjDoubleConsumer<Integer> objDoubleConsumer = (i1, d1) -> System.out.println(i1 + " + " + d1 + " = " + (i1 + d1));Integer i1 = 100;double d1 = 12.32;// calling the accept methodobjDoubleConsumer.accept(i1, d1);}}
Explanation
In the code above, we create an implementation of the ObjDoubleConsumer interface that accepts an integer i1 as the object argument and double d1 as a double value argument. Our code prints the sum of the arguments to the console.
