What is the difference between method and main method in Java?

Classes should be named with an uppercase letter, and be concise, for example Customer or Product. Method names begin with a lowercase letter, with subsequent words in uppercase . They are actions and should be verbs.

Every method has to be part of a Class. The difference between a main method (actually the main method which you are talking about) and any other method is that execution of the program starts at the main method . A method represents a functionality or a set of instructions that have been grouped together.

A class is a blueprint of an object. You need to have a class before you can create an object. Objects have properties and methods. A method is a procedure associated with a class and defines the behavior of the objects that are created from the class.

Yes, It is allowed to define a method with the same name as that of a class . There is no compile-time or runtime error will occur.
