What is a DoubleFunction Interface ?

As a software developer, the utilization of Java’s built-in functional interfaces can simplify and expedite the development process. In particular, the use of the DoubleFunction functional interface is an excellent way to streamline operations and improve the efficiency of code. DoubleFunction is an interface from the java.util.function package of the Java 8 library, first released in 2014. This interface is a functional interface which takes a double-valued argument and returns a result of type R. The interface accepts a single argument of type double and returns a result of type R. It is used to apply a function to an argument of type double and return a result of type R. The benefits of using the DoubleFunction functional interface include increased efficiency and a simple, straightforward usage process. This blog post will discuss the specifics of the DoubleFunction functional interface, including its properties and uses, and how to get the most out of the interface in software development. We will also explore how to use the interface
