[gcsupernova]

can you tell me what is the definition of public, static and void?

[zaychenok]

@gcsupernova public - others methods in other classes can call this method. static: the method exists independent of the class and class variables (you dont need an instance of the class to invoke the method). Void is the return type - what the method "gives back". void means that the method returns nothing in this case.

@cronnin you have to use the same name. The reason for this is that when you run the program the jvm(java virtual machine) uses the name of the class to access the method main() to begin execution
