Assignment:

The class RoachPopulation simulates the growth of a roach population. The constructor takes the size of the initial roach population. The breed method simulates a period in which roaches breed, which doubles their population. The spray method simulates spraying with insecticide, which reduces the population by 10%. The getRoaches method returns the current number of roaches. A program called, RoachSimulation simulates a population that starts out with a specific number of roaches. Breed, spray and print the roach count. Repeat three more times.

Sample output:

Enter the number of roaches in the population

25

Creating the Roach Population

The initial size of the population is 25

Breeding and Spraying

After breeding and spraying 1 times the roach count is 45

Breeding and Spraying

After breeding and spraying 2 times the roach count is 81

Breeding and Spraying

After breeding and spraying 3 times the roach count is 146

Breeding and Spraying

After breeding and spraying 4 times the roach count is 263

Include the following for the RoachPopulation class:

1. The instance variable of the class, RoachPopulation

2. The methods of the class, RoachPopulation

3. Include 2 constructors: No-arg and one that accepts the initial size of the population

4. Add getters and setters for instance variables

5. Include the breed and spray methods

Include the following for the RoachSimulation class:

1. A main method which creates the RoachPopulation object, calls all the required methods and prints the output.

2. A Scanner object must be used.

3. The class should work for all values entered by the user.

4. The output should look like the sample output above.

Please note the following requirements and how the assignment will be graded:

Two classes submitted and named as required: RoachPopulation and RoachSimulation
