You are to write a program that uses recursion to find all family ancestors and descendants of a given person. The program asks for the name of the family data file and then prompts for a specific person's name. If the person is in the family database, the program shows all the ancestors and all the descendants for that person. For ancestors it must show all parents, all grandparents, all great grandparents, etc. For descendants it must show all children, all grandchildren, all great grandchildren, etc. The program also must use indentation to make it clear who is a parent of whom and who is a child of whom. As a test data file, you will be using information about the Tudor kings and queens of England. The name of the file is "tudor.txt". Format of tudor.txt: The first section of the file (until the line with "END" has all the unique family members. The section of the tudor.txt after the "END" is divided into groups of three - first the family member, then his/her mother, then his/her father. This is how you can tell who is related to whom. i.e.: Arthur Family Member Elizabeth of York -> Mother Henry VII > Father Henry VIII > Family Member Elizabeth of York -> Mother Henry VII -> Father etc. Special cases: The data file contains no information prior to Henry VII, so when you ask for information about him, you get a lot of descendants but no ancestor information. Below is the log of execution you should obtain for him. What is the input file? tudor.txt Person's name ('quit' to end)? Henry VII Ancestors: Henry VII Descendants: Henry VII Arthur Henry VIII Mary I Elizabeth I Edward VI Margaret James V Mary Mary, Queen of Scots James VI & I Margaret Stuart Henry, Lord Darnley James VI & I Frances Descendants: At the other extreme is James VI of Scotland who became James I of England. The data file has no information about his descendants, but a great deal of information about his ancestors. Below is the log you should obtain for him. Lady Jane Grey What is the input file? tudor.txt Person's name ('quit' to end)? James VI & I Ancestors: James VI & I Mary, Queen of Scots Mary of Guise James V Margaret Elizabeth of York Henry VII Henry, Lord Darnley Margaret Stuart. James VI & I James IV Margaret Elizabeth of York Henry VII Your task: You are required to demonstrate that your program works for these two individuals and for another in the middle of this family tree. In particular, you should test it for Margaret. Below is the log you should obtain for her. What is the input file? tudor.txt Person's name ('quit' to end)? Margaret Ancestors: Margaret Elizabeth of York Henry VII Descendants: Margaret James V Mary, Queen of Scots James VI & I Margaret Stuart. Henry, Lord Darnley James VI & I Your client program should be named "Relatives.java" and it should include only static methods. It should prompt the use for the test file and then for the name of the person. If the name does not exist it should print a message and quit. If the name exists it should print the ancestors and descendants as shown in the above examples. Design Hints: Feel free to structure your program according to your preferences but remember that a crucial aspect of being a proficient software engineer is paying careful attention to the design of your program. Consider structuring your program to enable the client program to read the provided family file, store family information, and utilize recursive methods to print ancestors and descendants when given a person's name. Your grade will reflect the quality of your object-oriented design skills. Make sure that you're writing object-oriented code and that the ancestors and descendants are produced using recursive methods. You should also explain these methods in your README.txt file.
