public – accessible anywhere private – only accessible within the class or struct protected – only accessible within the same hierarchy internal – only accessible by the same assembly
mechanism to read, write, or compute the value of a private field.
getting and setting values, while hiding implementation or verification code.
class TimePeriod { private double seconds; public double hours { get { return seconds / 3600; } set { seconds = value * 3600; } } }
the set accessor.
class Program { static void Main() { TimePeriod t = new TimePeriod(); // Assigning the Hours property causes the 'set' accessor to be called. t.Hours = 24; // Evaluating the Hours property causes the 'get' accessor to be called. System.Console.WriteLine("Time in hours: " + t.Hours); } } // Output: Time in hours: 24
using System.Collections; ArrayList list = new ArrayList(); list.Add(1); list.Add(2); foreach (int i in list) { int j = i; }
If you use generic containers (e.g., ArrayList), casting is implicit, unlike Java where you have to explicitly cast.
A class can inherit a base class and also implement
public class ChildClass : InterfaceName public class ChildClass : ParentClass public class ChildClass : ParentClass, IInterface1, IInterface2 …
Based on your walkthrough and the problems you have identified, create updated designs for your prototype that incorporate your solutions.
