Can 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.
can you please help me with the last part of this code because I don't understand this; part of the code is below and the other part of the code is in the photo. question: In the LightsOutPuzzle class, write a method copy(self) that returns a new LightsOutPuzzle object initialized with a deep copy of the current board. Changes made to the original puzzle should not be reflected in the copy, and vice versa. >>> p = create_puzzle(3, 3)>>> p2 = p.copy()>>> p.get_board() == p2.get_board()True >>> p = create_puzzle(3, 3)>>> p2 = p.copy()>>> p.perform_move(1, 1)>>> p.get_board() == p2.get_board()False In the LightsOutPuzzle class, write a method successors(self) that yields all successors of the puzzle as (move, new-puzzle) tuples, where moves themselves are (row, column) tuples. The second element of each successor should be a new LightsOutPuzzle object whose board is the result of applying the corresponding move to the current…
Copy your previous class definition for RectangularSolid from the previous problem, including both methods. Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators). These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.
Please answer the question in the screenshot. The language used is Java.
Redefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method. (Remember, you should use getClass(), not instanceof.)
This is Java project plz solve it thanks!
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…
Add a constructor to the Point class that accepts another Point as a parameter and initializes this new Point to have the same (x, y) values. Use the keyword this in your solution.
Don't give me AI generated answer or plagiarised answer. If I see these things I'll give you multiple downvotes and will report immediately.
Please look at the images for the programming question. I am not sure sure where I should start on this. All coding is done in Java, using IntelliJ Idea.
In this exercise, you are going to build on your Circleclass from the previous exercise. You are going to add 2 method, areaDifference and perimeterDifference. Both methods take a doubleradius of a second circle and return the difference from the current circle. For example, if you create a Circle object with a radius of 4 and call areaDifference(3), you will return the diffence between the area of a circle with radius 4 and the area of a circle with a radius of 3. perimeterDifferencewould be the same. Make sure you create at least one Circle and test and print the results of your methods. in java
