18. When you write you own constructor, the default constructor is no longer available. True O False

Setters are those methods in the class which are used to set or initialize the class fields. Since they don’t have to return anything, their return type is set to ‘void’.
To use a class field in some other class (in case it is not being inherited), they need to be declared public.
The static members of a class are not bound with an instance of the class but with the class itself. Therefore, they can be accessed using the class name only without instantiating it.
