I wonder. Since we don't need to declare a variable, does this mean that a variable which first I assign a numeric value can be assigned later with, for example, string value?

void means 'no return value' then is that different with a method 'println()' ?? I don't understand the difference between return value and println()...!

What if I create a private variable inside the main class, would that mean it'll be available in other classes? What do private variables even do?
