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
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 xxx_RoachPopulation class:
1. The instance variable of the class, RoachPopulation
2. Include 2 constructors: No-arg and one that accepts the initial size of the population
3. Add getters and setters for instance variables
4. Include the breed and spray methods
Include the following for the xxx_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
Two classes submitted and named as required: xxx_RoachPopulation and
xxx_RoachSimulation
A comment at the start or the program describing what the program does
Coding style: All code must be indented for readability and consist of only one statement per line. Naming conventions followed for variables and methods
RoachPopulation class:
o Instance variable
o Constructors
o Getter
o Setter
o breed method
o spray method
RoachSimulation class:
o Scanner object
o Prompt to user and getting value
o RoachPopulation object created
o Loop used to breed, spray and print message
o Methods breed and spray called correctly
o Output matches sample output in format
