Add a further integer field, borrowed, to the Book class. This keeps a count of the number of times a book has been borrowed. Add a mutator, borrow, to the class. This should update the field by 1 each time it is called. Include an accessor, getBorrowed, that returns the value of this new field as its result. Modify printDetails so that it includes the value of this field with an explanatory piece of text.

- create two data members on each of the four classes we created (MyPoint, Mysegment, MyShape, and xyGroup). You also need a boolean, to declare it picked, and a color to paint it. also create a method called select (or pick). So we add the two new members, color and isselected:arrow_forwardCreate a code the follow way: Each student object should also contain thenumber of earned credits. Provide a constructor that sets this value based on parameter value. Overload theconstructor such that the number of earned credits is initially zero. Provide setter and getter for this newfield. Modify the toString method such that the new information is included in the description of thestudent. Modify the driver class main method to exercise the new Student methods.arrow_forwardCreate one more method in the Starship class: encounter(self, enemy_ship) This method takes in self, along with another Starship object. The method should simulate a battle between the two ships. How the method is implemented is almost entirely up to you. You could take in user input for each crew member, or have them each act randomly from the available options, or specify exactly what a given crew member of each type should do. The only requirements are as follows: Each crew member on each ship should get at least one “turn” before the battle is complete. If the crew member is Injured on their turn, they should do nothing. You may assume that each ship will have at least one crew member uninjured when the encounter begins. You shouldn’t make any assumptions about how many crew members there will be on a given ship, where they will start, or about which subclasses will be present - it’s possible that you’ll have test cases including a ship with no captain, or no doctor.…arrow_forward
- Please help me create a cave class for a Hunt the Wumpus game (in java). You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how…arrow_forwardCreate a new project for this program called TestOldMaid and add a class with a main() method. In the project: Copy your Deck and Card class from the earlier project into it. Create a subclass of Deck called OldMaidDeck. It is special because one of the Queens is missing so it only has 51 cards. Create a constructor method that calls the super class constructor, then removes a queen. Override the toString method so it returns the name of the deck and the number of cards in it. Write the test main() method. Create an OldMaidDeck object and deal all the cards to six players. It is ok if not everyone has an equal number of cards. Use arrays or ArrayLists for the players hands. Show the hands of all 6 players. Refer to the web to find out more about the Old Maid card game. Fully document all classes with your name, date and description. And each data member and method is documented. Each block that does something is also documented.

- SELECT ALL the members of the class that are accessible by classes in the same package as Bicycle. Take note: In your response, leave off the constructor(s).arrow_forwardWrite a Dice class. The class should have: A private field for the number of sides of the die. A constructor that takes an integer between 4 and 20, inclusive and sets the number of sides of the die. A method, rollDie(), returns the face value when the die is rolled. Use a Random number to “roll” the die. Write a main method that will create two die with the same number of sides, continually roll the dice, and report the result of each roll. It should stop when “snake eyes” are rolled (double 1’s) and report the number of rolls. You may write this as a console application or a Windows Forms application; include a screenshot of your program running with successful output.arrow_forwardCan you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.arrow_forward
- Create a PhoneListing class that uses the Name class for one of its instance variables. Remember the instance data in the Name class is private to the class and must be accessed through its methods.Add additional instance variables to the PhoneListing class for the phone number. The phone number should be broken down into three parts, area code, city code, and local code.Create all appropriate methods for the new class, including the following three methods: equals(PhoneListing):boolean, an equality of state method that returns true if the objects contain the same name and phone number. compareTo(PhoneListing):int, a comparison method that returns -1 if the calling PhoneListing object should precede the argument PhoneListing object, 1 if the calling PhoneListing object should come after the argument PhoneListing object, and a 0 if they are equal. Use last, first, middle, phone number as the ordering values. example:Adams, Alex, Henry, (609)473-2101 Adams, George, Henry, (509)373-1101…arrow_forwardWrite an accessor method called getName that returns the value of a field called name, whose type is String.arrow_forwardWrite a mock Armor class.
