So Basically This is an Command Line Tool Jar for Managing Family Tree (Wanted to Build a native interface though)

System Requirements: JDK-17,JRE17

So yeah I've attached an Jar in this Repository

It supports Commands such as:

1. add Person [name] : where name is a single word
2. add relationship [relationshipname] : where relationshipName is a single word
3. connect [name] as [relationshipname] of [name2]

And Query Commands Such as

4. count sons of [name]
5. count wives of [name]
6. count daughters of [name]
7. father of [name]

So for example you've to add a person named zeeshan your command would be something like

1)java -jar family-tree-cli.jar add Person zeeshan

2)java -jar family-tree-cli.jar add Person Iftekhar

Similarly for connecting

java -jar family-tree-cli.jar connect ifte as father of zeeshan

for Queries

java -jar family-tree-cli.jar count sons of Iftekhar java -jar family-tree-cli.jar count daughters of Iftekhar java -jar family-tree-cli.jar father of zeeshan

How to use being said I'll Explain the Thought Process behind my design :-

Every Gender is derived through Relations in this program

So Lets say Iftekhar is father of zeeshan

What this specify is that the father is Male , So we dont know what the Child Gender is unless We Connect that Child as son of his . Similarly When we add someone as someone's mother , The Child has a mother which is female but the child gender is unspecified unless we connect that child as son or daughter of that Person

That Being Clear Few Cases That I've considered :-

Lets say PersonA has 2 kids and PersonB has 2 kids So if they marry each other Both of them have 4 kids

If you add personA as father of personB Then count sons or daughter of personA you would get 0 because the gender of child isn't explicit

Apart from this Everything is pretty straight forward

Male can have multiple wives and vice versa (This wasn't clear for me However)

Regarding Using only One Object Human

which have following properties:-

String name ;
Human father;
Human mother;
List<Human> SO;
List<Human> kids ;
String gender ;

We can Recursively add relations to this because each Human has the above properties

Here is an image of the operations:-
