I'm designing an RPG game in java and would like some help with my experience gain class for my characters. So far I only have character classified as either Magic or Martial(warrior) and I need to implement an xp system that determines if they have leveled up or not. I started coding the outlook of my character xp class, which I have shown below but I would like some help with filling the gaps Right now I'm just using a simple level up in 1007 increments and simple attack and defense for my characters for my outline. Any help or different approaches to filling out my xp class would be appreciated.

public abstract class CharacterClass { // Manages level/xp protected int level; protected int currentXP; protected int perLevelHP; protected int perLevelAttack; protected int perLevelDefense; public CharacterClass() { this.level = 1; this.currentXP = 0; } protected int getLevel() { return level; } protected int getCurrentXP() { return currentXP; } protected boolean addXP(int xpGain) { // XP gain this.currentXP += xpGain; // Need a Level UP formula Level that uses a * 1007 = XP needed? per level // Level 1 need 1007 xp, level 2 needs 2014 xp ... etc if(this.currentXP >= this.level * 1007) { this.currentXP = 0; return true; //return true if character has leveled up } return false; // A false means no level up } } ******************************************************* public class MagicClass extends CharacterClass { public MagicClass() { this.perLevelAttack = 10; this.perLevelDefense = 5; this.perLevelHP = 5; } } ************************************************************** public class MartialClass extends CharacterClass { public MartialClass() { this.perLevelAttack = 5; this.perLevelDefense = 10; this.perLevelHP = 10; } }
