void vs non void methods
-void : does not return any value. The "void"
return type means that this method doesn't
have a return type.
In an application, this approach may be used
to print runtime specific messages on the console.
Exp: "setter" in encapsulation.
-non-void: MUST return a Value.
(Data type needs to be same with return-type)
This means that you can use the returned
value in your code for further processing.
I guess good examples of such methods are "getter" in encapsulation.
Are there any code examples left?
