Explanation of Solution

Difference between instance variable and local variable:

Instance variableLocal variable
In object-oriented programming, the data field in the class is known as instance data field or instance member variable.The variable declared inside the specific method and which does not provide any access to other method is called local variables; they are recreated every time a function is called.
Every instance of the class has its individual copies of the class instance variables.Access modifiers cannot be used for local variables.
Without disturbing any other instances, one object instance can change the values of its instance variables...
