The
DoubleBinaryOperator interface was introduced in Java 8. It represents an operation on two double values and returns the result as a double value. It is a
functional interface and thus can be used as a lambda expression or in a method reference. It is mostly used when the operation needs to be encapsulated from the user.
Methods:
-
applyAsDouble(): This function takes two double values, performs the required operation and returns the result as a double.
public double applyAsDouble(double val1, double val2)
Example to demonstrate DoubleBinaryOperator interface as a
lambda expression .
Output:
x + y = 13.221
x - y = 2.0869999999999997
x * y = 42.609818000000004
x / y = 1.3748877312735763
x % y = 2.0869999999999997
