public class RunePlayer {

    private HashMap<Skills, Integer> skills = new HashMap<Skills, Integer>();
    private HashMap<Skills, Integer> skillXP = new HashMap<Skills, Integer>();
    private String name;

    public RunePlayer(String name) {
        new RunePlayer(name, 1, 1, 3, 10, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, …
