Tag: What is function in Java with example?

A method is a block of code which only runs when it is called. You can pass data, known as parameters, into a method. Methods are used to perform certain actions, and they are also known as functions .

Static methods : A static method is a method that can be called and executed without creating an object. … Instance methods: These methods act upon the instance variables of a class. … Factory methods: A factory method is a method that returns an object to the class to which it belongs.

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.
