instance variables
An instance variable has similarities with a class variable, but is non-static. An instance variable is a variable which is declared in a class but outside of constructors, methods, or blocks. ... It is a type of class attribute (or class property, field, or data member).
CANNOT be overridden in Java. In Java, only methods can be overridden. When you declare a field with the same name as an existing field in a superclass, the new field hides the existing field. The existing field from the superclass is still present in the subclass, and can even be used ...
Can member variables be overridden?
In short, no, there is no way to override a class variable. You do not override class variables in Java you hide them. Overriding is for instance methods. Hiding is different from overriding.
Why data members Cannot be overridden?
This is because variables in Java do not follow polymorphism and overriding is only applicable to methods, not variables. And when an instance variable in a child class has the same name as an instance variable in a parent class, then the instance variable is chosen from the reference type.
