1 You have studied encapsulation and inheritance that are two important concepts of Object- Oriented Programmin and write a program of your own choice in it that can explain these concepts, and in the context of that program.And Also write the main method that can test the classes. write your answer below that will explain 1. How encapsulation and inheritance was achieved in this program? 2. What are the benefits you get after implementing encapsulation and inheritance in this program? 3. What are the disadvantages if you will not use encapsulation and inheritance in this program?

Explain the concept of method overriding in object-oriented programming. Provide an example using a base class and a derived class to illustrate how method overriding works.
Based on the class diagram image below, create customer, car, and parking lot classes for an object-oriented parking system. Classes should contain properties and method implemetaions. Include a small write-up about your implementation.
Why is the ability to redefine a method important in object-oriented programming?Choose all options that apply.(a) Because it allows us to add extra work to a method.(b) Because it allows us to introduce abstract methods that are redefined as concrete methods.(c) Because it allows us to provide a more accurate or faster definition in a subclass.(d) Because it allows us to disable a method in a subclass.(e) Because it allows us to change the meaning of a method.
Question 3:1. Explain the importance of method signature in method overriding.2. The system might want to use an overridden method (function) with a common signature across therelevant classes Seller, Dealer, Buyer, and distinct classes Car and Invoice for maintaining thefinances. Details of the classes can be seen in Table 1. Explain with proper syntax as to how this canbe achieved using object-oriented programming.3. Write Java code (for the methods only) that implements the method with the same signature for eachclass with the following details:a. Calculates the commission earned by the dealer. A dealer charges 1% commission eachto the buyer and seller on sale price of the car.b. The profit or loss for the seller. A seller earns profit (incurs loss) computed as thedifference between the sale and purchase price of the car. Sales Tax is deducted at therate of 17% on the profit earned. No sales tax is charged in case of loss. The methodshould display an appropriate message…
Why does avoiding classes that are needlessly connected require more work and writing of code in object-oriented programming? What are your position's three primary justifications?
