What is a IntToLongFunction Interface ?

Java 8 introduced several new features to the language, with one of the most powerful being the introduction of functional interfaces. The Java IntToLongFunction functional interface is a prime example of how this technology can be used to improve code readability and performance. This particular interface is a subinterface of the Functional Interface and provides a method to convert a primitive int to a primitive long. This interface is especially useful for developers who need to work with large numbers or require precision. In this blog post, we will discuss the uses of the IntToLongFunction interface and how it can be implemented in code. We will also provide examples of how this functionality can simplify existing code and make programs more efficient.
