Answer 1

ii) Variable Shadowing

Reason: There are following reasons for considering a variable shadowing, they are listed below:

• When we define a variable in a local scope with a variable name same as the name of a variable defined in an instance scope.
• When a subclass declares a variable with the same name as of the parent class variable.
• When a method is overridden in the child class.
