Explanation
Instantiation is creating an instance of a class. In simple terms, it's creating a variable. It is said that the variable is an instance of the class.
Skeleton Program Example
//This is the class:
class Simulation
{
private Location[,] Landscape;
private int TimePeriod = 0;
private int WarrenCount = 0;
private int FoxCount = 0;
private bool ShowDetail = false;
private int LandscapeSize;
private int Variability;
private static Random Rnd = new Random();
public Simulation(int LandscapeSize, int InitialWarrenCount, int InitialFoxCount, int Variability, bool FixedInitialLocations)
{
int menuOption;
int x;
int y;
string viewRabbits;
this.LandscapeSize = LandscapeSize;
this.Variability = Variability;
Landscape = new Location[LandscapeSize, LandscapeSize];
CreateLandscapeAndAnimals(InitialWarrenCount, InitialFoxCount, FixedInitialLocations);
DrawLandscape();
do
{
Console.WriteLine();
Console.WriteLine("1. Advance to next time period showing detail");
Console.WriteLine("2. Advance to next time period hiding detail");
Console.WriteLine("3. Inspect fox");
Console.WriteLine("4. Inspect warren");
Console.WriteLine("5. Exit");
Console.WriteLine();
Console.Write("Select option: ");
menuOption = Convert.ToInt32(Console.ReadLine());
if (menuOption == 1)
{
TimePeriod++;
ShowDetail = true;
AdvanceTimePeriod();
}
if (menuOption == 2)
{
TimePeriod++;
ShowDetail = false;
AdvanceTimePeriod();
}
if (menuOption == 3)
{
x = InputCoordinate('x');
y = InputCoordinate('y');
if (Landscape[x, y].Fox != null)
{
Landscape[x, y].Fox.Inspect();
}
}
if (menuOption == 4)
{
x = InputCoordinate('x');
y = InputCoordinate('y');
if (Landscape[x, y].Warren != null)
{
Landscape[x, y].Warren.Inspect();
Console.Write("View individual rabbits (y/n)?");
viewRabbits = Console.ReadLine();
if (viewRabbits == "y")
{
Landscape[x, y].Warren.ListRabbits();
}
}
}
} while (((WarrenCount > 0) || (FoxCount > 0)) && (menuOption != 5));
Console.ReadKey();
}
//And so an instance can be created from anywhere within a program, for example...
Simulation Sim;
