A method that returns 'void' means it does not return anything.
Void methods usually change something. Ie. Mutator methods that change a variable.
And for methods that return something:
Say you wanted to get the value of a private variable of another class, you would use an accessor method to return this variable.
In short:
Methods that return void return nothing.
The rest return something. Ie. Integers, Strings etc.
