Question 2.
Requirement Type
The user will choose a colour and obtain a SW hardcopy swatch (print of colour)
The action is started by pressing a “Choose” SWC button 20
The user will be shown a colour wheel SWC 20
The user selects a colour from the colour wheel SWC 20
If the printer has paper then a colour swatch is SWC produced 20
If the printer does not have paper then an SWC error message is displayed 20
Use Case
UC20 Print Swatch
Education Australia needs you to design a database for their organisation. After conducting some analysis, you have collected the following information:
• Students can be studying at Kindergarten, Primary School, High School, College, or University level
• Children belong to a school which has a name
• Children can hold the capability to be an A, B, or C student
• Each level has a time limit (1 year for Kindergarten, 6 years for Primary School, 4
years for High School, 2 years for College, and 3 years for University) and the
child can determine how many more years remain in that level
• Each child has preferred activities which they can describe (i.e. produce a string).
Activities vary according to section and by the child’s preferences
• Preferences are named and may be writing or mathematics or art or ICT. Each
child has a single preference although preferences can be shared by many
children
• Preferences can be counted to determine the number of children with that
preference. This action returns a whole number between 0% and 100%.
Draw a UML class diagram that best describes the above information. Include attributes and methods that are mentioned in these classes. (Treat actions, like explained or counted, etc as methods.) Include multiplicities, enumerations, specialisation, and so one, where relevant.

Question 3.
Draw a UML sequence diagram to show what happens when the following classes are executed.
class Program {
static void Main(string[] args) {
} }
A a = new A();
B b = new B{ Thing = a }; C c = new C();
b.Run2();
c.Show(a);
class A {
public void Run(C c) {
c.Show(this); }
}
class B {
public A Thing { get; set; }
public void Run() {
Run2(Thing);
}
public void Run2(A) { C c = new C();
a.Run(c); }
}
public void Show(A a) { /* code to be written */ } }

Question 5.
Consider the following class diagram. Write C# code to declare the classes and enumerations contained within the diagram. Do not include using or namespace declarations in your answer.
You may assume that all required namespaces are available. Each attribute must be a public, auto-generated property. Any methods you write should be stubs, with an appropriate header but no code within their body { }.
