2.3.1 How to Represent Read-only Lists in a Class Diagram

3.Open your 2.2 Class Diagram in Violet

A Verify the required change or observation

Check the result against this instruction: Open your 2.2 Class Diagram in Violet

4.Modify the Terminal class so it has a readonly list of Gates instead of two fields named GateA and GateB

A Verify the required change or observation

Check the result against this instruction: Modify the Terminal class so it has a readonly list of Gates instead of two fields named GateA and GateB.

5.Verify the diagram against the evidence

A Inspect the rendered diagram

Open or render your diagram, inspect every label and relationship, and compare it with the code or debugger state. Resolve syntax errors, clipped labels and unreadable crossings before submission.

Represent the object view

6.Review the notation example

A Identify the notation used in this view

Object identity and list order example. object "items : List<Example>" as items object "first : Example" as first { value = 7 } object "second : Example" as second { value = 9 } items --> first : [0] items --> second : [1] — Object identity and list order example

8.Represent a list of Gates from the Terminal class in order of and based on the object values below

A A Gate that has a HasSkyway value of true, a Name of GateA and a Distance of 250

B A Gate that has a HasSkyway value of false, a Name of GateB and a Distance of 120

C A Gate that has a HasSkyway value of true, a Name of GateC and a Distance of 480

9.Verify the diagram against the evidence

A Inspect the rendered diagram

Open or render your diagram, inspect every label and relationship, and compare it with the code or debugger state. Resolve syntax errors, clipped labels and unreadable crossings before submission.

11.Open a new Activity Diagram in Violet

A Verify the required change or observation

Check the result against this instruction: Open a new Activity Diagram in Violet

12.Represent the following code in an Activity Diagram

There is no need to represent the return statement.

double totalTickets = 0;
foreach (Gate g in this.Gates)
{
    totalTickets += g.NumberOfTickets;
}
return totalTickets;

A Verify the required change or observation

Check the result against this instruction: Represent the following code in an Activity Diagram.

13.Verify the diagram against the evidence

A Inspect the rendered diagram

Open or render your diagram, inspect every label and relationship, and compare it with the code or debugger state. Resolve syntax errors, clipped labels and unreadable crossings before submission.
