Chapter 9, Problem 10E

Suppose that you are going to create an object used to count the number of people in a room. We know that the number of people in the room can never be negative. Create a RoomCounter class having three public methods:

  • addPerson—adds one person to the room
  • removePerson—removes one person from the room
  • getCount—returns the number of people in the room

If removePerson would make the number of people less than zero, throw a NegativeCounterException.

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!”.
Problem: Bugs are simple creatures that only know how to walk towards other bugs. Bugs maintain information about their (x, y) position; by which it can tell if they are standing next to other bugs. Watch the following video: bug movement. Create a java project that simulate bugs movement. You need to write a class “Bug" that models a bug moving along a straight line and it can turn to change its direction counterclockwise (i.e. 90 degree to the left; north → west → south → east → north). In each move, its position changes by one unit in the current direction. Details of the "Bug" class is described below. Your simulator should read information of an unknown number of “Bug" objects from an input file called “Bugs.txt". Each line represents a bug and the initial position and facing direction of this particular bug. Keeping the first bug position as a reference the simulator should move the second bug next to the first bug forming a cluster and its final position and direction should be…
In java language Write a Rectangle class. A Rectangle has properties of width and length. 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…
