Methods

Methods define actions that a class's objects (or instances) can do. A method has a declaration part and a body. The declaration part consists of a return value, the method name, and a list of arguments. The body contains code that perform the action. The return type of a method can be a primitive, an object, or void. The return type void means that the method returns nothing. The declaration part of a method is also called the signature of the method. For example, here is the getSalary method that returns a double. public class MainClass {   double getSalary() {     return 0.0;   } }
