Create A DND character creator Java Code

I need help creating a Dwarf and Dragonborn character class in Java.

Races: D&D hosts many playable races one can choose from, with each race having its benefits. Some races are even further divided by their sub-race. Each subrace tends to inherit most aspects of its primary race with minor changes (mainly to stat bonus’). The Dwarf would have the sub-races Hill Dwarf and Mountain Dwarf. A standard race has about six traits; Ability Score increase, Age, Alignment, Size, Speed, and Language. Of these aspects, Ability Score increase, Speed, Size type, and Language are the only ones that are needed.

Each superclass will have four core values: Ability Score increase, Speed, Language, and Size type.

Ability Score increase: Split in two, an int and a string

Speed: integer

Size Type: String

Lang: string array

Dragonborn ancestry: String for color and damage type.

I have included files that I believe will be helpful in creating the classes necessary
