Main Methods

Now let’s discuss the different forms of methods. Firstly, there are main methods. Main methods have no return type and are called implicitly, meaning that there is no need to call them. When you run a program, the main method of the class you are running is called automatically. When you call a method, you invoke the statements inside them. The only arguments they take in are an array of strings. These arguments are not required for the program to function, unless, of course, the program makes use of these arguments. When you declare a main method, that method is executed automatically when that file is run, hence the name main method. Often times, when you want to write a basic program that doesn’t make use of objects, you write the program in the main method.
