In the ABC business model an organization consists of many members.
A member may have a spouse and children.
Of course the spouse and children of a member may also be members or they may simply be dependants.
Every dependant must be sponsored by exactly one member.
All persons, whether members or dependants, have the following attributes:
last name
first name
dob (date of birth)
gender (male/female)
id (a unique identification string)
All persons have a toString method that returns these attributes as a nicely formatted string.
A member's spouse and children may be members or dependants.
Use the Composite Pattern to design and implement this part of the ABC business model.
Begin be sketching a UML class diagram.
Next, translate your sketch into a Java implementation.
Provide a displayDependants method in the Organization classes that displays all dependants of members in the organization and their sponsors (use the toString method above).
Test your implementation by declaring a class called TestOrganization. The main method of this class creates an organization and populates it with various members and dependants described in org1.xml. Finally, call the displayDependants method.
