Learn how to write and use functions in Java, including syntax, structure, types, naming conventions, and modifiers. Explore examples of standard, getter, setter, static, constructor, and overloaded functions.

The Function Interface is a part of the java.util.function package that has been introduced since Java 8, to implement functional programming in Java. It represents a function that takes in one argument and produces a result. Hence, this functional interface takes in 2 generics, namely as follows T denotes the type of the input argument

Learn how to use the Function interface in Java to create and apply functions that accept one argument and produce a result. See examples of simple, complex, and functional programming with Function.

A method is a block of code that performs certain actions and can be reused. Learn how to declare, define, and call methods in Java with examples and explanations.

Learn how to create and call functions in Java, also known as methods, and the advantages of using them. See the syntax, structure, types, and overloading of functions with examples and code snippets.

Functions. In Java, all function definitions must be inside classes. We also call functions methods. Let's look at an example method. public class Main public static void foo Do something here foo is a method we defined in class Main. Notice a few things about foo. static means
