FamilyTreeV2

A small console application for building and displaying a family tree, written as a practice exercise for a university Data Structures and Algorithms module. This is version 2 of the exercise, adding unique identifiers and extended functionality over the first version.

Features

• Add partners to any family member
• Add children to any member with a partner
• Display the whole family tree or a specific branch
• Every family member is assigned a unique ID automatically

How it works

The tree is implemented from scratch (no library collections for the tree itself) using a first-child / next-sibling node structure:

• src/FamilyTree.java contains the FamilyTree class and its inner FamilyTreeNode class
• src/FamilyTreeTest.java contains the interactive menu-driven test program

Running

Requires a JDK (developed with JDK 23, but any recent version should work).

javac -d out src/*.java
java -cp out FamilyTreeTest

Then follow the menu prompts:

1. Enter the ancestor's name
2. Use the menu to add partners and children by ID
3. View the entire tree or a specific branch
4. Select quit to exit
