If you run an java file(as an .class or .jar file) there's always 1 method being called: The main(String[] args) method.
The method is only called once.
Example of an main method:
public static void main(String args[]) throws IOException {
LoggingBootstrap.bootstrap();
gui = new GUI();
}
In this case it only bootstraps the logger and uses the constuctor method of GUI(the graphical user interface of the program)

Test.show();\\this is correct } Arnas Sinha

What is the difference between function and method?
functions have independent existence means they are defined outside of the class e.g. in c main() is a function while methods do not have independent existence they are always defined inside class e.g. main() in Java is called method. ######## I've been studying OOP lately and had this question myself, so I will share my thoughts; I was taught that "A Function should do 1(one) thing and do it well." In specific Regards to PHP; The difference between a Method and a Function is that a Method is tied to a specific class. Hope this helps. -------------------------------------------------------------------------------------------------------- function can return value where as method can't that is the main difference between function and method --------------------------------------------------------------------------------------------------- Actually you are describing the difference between a function and a procedure. Function returns a value, procedure does not unless you are using c#, then everything is a function. In c# a function, to paraphrase the first answer, does and thing and does it well. A method contains functions. The most important method is the Main method. All functionality of a program must be referenced in the Main method because when you run a program, it starts at the beginning of the Main method, and stops wehn it hits end of the Main method.
