Let's talk about another important topic—namely methods. A method is a piece of code that is written in the code file and can be reused. A method can hold many lines of code, which will be executed when it is called. Let's take a look at the general form of a method:
access-modifier return-type method-name(parameter-list) {

}

Then, we have the return-type of the method, which will hold the type that the method will return, such as string, int, double, or another type. After that, we have the method-name and then brackets, (), which indicate that it is a method. In the brackets, we have the parameter-list. This can either be empty or can contain one or more parameters. Finally, we have curly brackets...
