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.
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…
Write a class for a Chicken that also implements your interface. The Chicken’s type will be “chicken” and the sound will vary. About 50% of the time, the chicken will say “bawk!” and other times it will say “cluck!”.

You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length. Remember that the job of the constructor is to initialize the instance variables. It has these methods. public double getWidth() - Gets the width of this Rectangle public double getLength() - Gets the length of this Rectangle public void…arrow_forward
