What is a IntToDoubleFunction Interface ?

Java 8 introduced many new features that made developing applications easier and more efficient. One of these features is the functional interface, which provides a way to create code that is more concise and easier to read. The Java IntToDoubleFunction functional interface is one of these interfaces that provides a simple way to convert a primitive int type to a primitive double type. This functional interface is a part of the java.util.function package, and it provides a functional interface that can be used to define a lambda expression to convert an int value to a double value. In this blog post, we’ll take a look at the details of the IntToDoubleFunction functional interface, including how to use it, what methods it provides, and how it can be used to make your code simpler and more efficient.
