Write a family database program. Create a class to represent a person and to store references to the persons mother, Father, and any children, AND ANY SIBLINGS that the person has. Read a file of names to initialize the name and the parent-child relationships of each person. (You might want to create a file representing your own family tree. Store the overall list of persons as an ArrayList. Write an overall driver class that asks for a name and prints the maternal and paternal family line of that person.

//PROGRAM DOES NOT INCLUDE SIBLING GETTERS / SETTERS / METHODS

You need to create the following classes:

Person class: Shell has been provided

FamilyInfo class: shell has been provided

FamilyTest class: shell has been provided

You also need to create a file representing the family info such as the following:

List the name of all the people in your family and end the list with the String End

For every person in the step a, write the following

Persons name

Persons mother

Persons father

You must create a file of the information about your own family. Here is a sample file

Henry VII Arthur Catherine of Aragon Henry VIII Anne Boleyn Jane Seymour Mary I Elizabeth I Edward VI Margaret James IV James V Mary of Guise Mary, Queen of Scots Henry, Lord Darnley James VI & I Mary Charles Brandon Frances Henry Grey Lady Jane Grey Elizabeth of York Margaret Stuart END
