TestScores Class
Design a TestScores class that has fields to hold three test scores. The class should have a constructor, accessor and mutator methods for the test score fields, and a method that returns the average of the test scores. Demonstrate the class by writing a separate

Class members are private by default and it's not possible to access them outside the class.
True
False
When you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class.
True
False
Static & Not Final Field: Accessed by every object, Changing
Non-Static & Final Field: Accessed by object itself, Non-Changing
Static & Final: Accessed by every object, Non-Changing
Non-Static & Not Final Field: Accessed by object itself, ChangingRead the following situation and decide how the variables should be defined.
You have a class named HeartsPlayerA round of Hearts starts with every player having 13 cardsPlayers then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep)Players then strategically play cards in order to have the lowest scoreAt the end of the round, points are cumulatively totaled for each player.If one player’s total is greater than 100, the game ends and the player with the lowest score wins.
1. How should the following data fields be defined (with respect to final and static)?(a) playerPosition (These have values of North, South, East, or West)(b) directionOfPassing(c) totalScore…

Include a constructor that requires arguments for both fields and a method named display to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display method should output: sausage and onion pizza Price: $14.99 Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields: deliveryFee - of type double address - of type String The description, price, and delivery address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5.

Books’s constructor shouldinitialize all of these data members except the price which is set to 500/-.

The PopularBooks subclass replaces theBookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the displaymethod to display all fields.Write a Main () method that declares an array of five Book objects. Ask the user to enter the title andauthor for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following:Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details.arrow_forwardWrite a class named Employee that has the following fields: name: The name field is a String object that holds the employee's name. idNumber: The idNumber is an integer variable that holds the employee's ID number. department: The department field is a String object that holds the name of the department where the employee works. position: The position field is a String object that holds the employee's job title. Write mutator methods that store values in these fields and accessor methods that return the values in these fields.

- Cargo Ships This question involves cargo ships that carry a specific number of cargo containers. Each ship has a maximum number of cargo containers that it can hold and a current number of cargo containers that it is holding. You can see more details in the Ship class that is provided for you. Part A For part A, you will be completing the nextToUnload() method. This takes no input and returns a Ship from the ships instance variable that has the highest percentage of its cargo hold filled (as measured by current hold / capacity). If two ships have the same percentage, then it should return the first ship with that percentage. If all of the ships in the ships array are empty (ie. no cargo), the method should return null. Part B For part B, you will complete the two unloadShip methods. The first method takes a Ship object and unloads all of the cargo from that ship. The second method takes a Ship and an int and unloads the specified number of containers from the ship.
