How to implement ToDoubleBiFunction using lambda expression in Java?
ToDoubleBiFunction<T, U> is a functional interface defined in java.util.function package. This functional interface accepts two parameters as input and produces a double-valued result. ToDoubleBiFunction<T, U> interface can be used as an assignment target for a lambda expression or method reference. This interface contains only one abstract method: applyAsDouble() and doesn't contain any default or static methods.
Syntax
@FunctionalInterface
interface ToDoubleBiFunction<T, U> {
double applyAsDouble(T t, U u);
}Example
import java.util.function.ToDoubleBiFunction;
public class ToDoubleBiFunctionTest {
public static void main(String args[]) {
ToDoubleBiFunction<Integer, Integer> test = (t, u) -> t / u; // lambda expression
System.out.println("The division of t and u is: " + test.applyAsDouble(50, 5));
System.out.println("The division of t and u is: " + test.applyAsDouble(100, 3));
}
}Output
The division of t and u is: 10.0 The division of t and u is: 33.0
