Util JsonConstructor

Hello! I made this class a couple of months ago and I thought i would share it with you guys enjoy!

Code:

public class JsonConstructor {
    /**
     *
     * @author ByteZ
     *
     */
    public enum ClickEvent{
        RUN_COMMAND, SUGGEST_COMMAND, OPEN_URL
    }
    ArrayList<String> text = new ArrayList<>();
    String json = "{text:\"";
    public JsonConstructor(String text){
        json +=text+"\"";
    }
    public JsonConstructor addText(String text){
        if(this.text.size() == 0){
            json +=",extra:[{text:\"" + text + "\"}";
        }else{
            json +=",{text:\"" + text + "\"}";
        }
        this.text.add(text);
        return this;
    }
    public JsonConstructor includesColor(ChatColor color){
        if(text.size() > 0){
            json = json.substring(0, json.length()-1);
            if(color.isColor()){
                json+=",color:"+color.name().toLowerCase()+"}";
            }else{
                json+=","+color.name().toLowerCase()+":true}";
            }
        }else{
            if(color.isColor()){
                json+=",color:"+color.name().toLowerCase()+"";
            }else{
                json+=","+color.name().toLowerCase()+":true";
            }
        }
        return this;
    }
    public JsonConstructor includesClickEvent(ClickEvent Action,String value){
        if(text.size() > 0){
            json = json.substring(0, json.length()-1);
            json+=",clickEvent:{action:" + Action.toString().toLowerCase()+",value:\"" + value + "\"}}";
        }else{
            json+=",clickEvent:{action:" + Action.toString().toLowerCase()+",value:\"" + value + "\"}";
        }
        return this;
    }
    public JsonConstructor includesHoverTextEvent(String value){
        if(text.size() > 0){
            json = json.substring(0, json.length()-1);
            json+=",hoverEvent:{action:show_text,value:\"" + value + "\"}}";
        }else{
            json+=",hoverEvent:{action:show_text,value:\"" + value + "\"}";
        }
        return this;
    }
    public JsonConstructor includesHoverAchievmentEvent(Achievement ach){
        if(text.size() > 0){
            json = json.substring(0, json.length()-1);
            json+=",hoverEvent:{action:show_achievement,value:achievement."+ach.name().toLowerCase().replace("_", "")+"}}";
        }else{
            json+=",hoverEvent:{action:show_achievement,value:achievement."+ach.name().toLowerCase().replace("_", "")+"}";
        }
        return this;
    }
    @Override
    public String toString() {
        if(text.size() > 0){
            return json+"]}";
        }else{
            return json+"}";
        }
    }
    public void send(Player p){
        ((CraftPlayer)p).getHandle().playerConnection.sendPacket(new PacketPlayOutChat(ChatSerializer.a(toString())));
    }
}

How to use:

Code:

        new JsonConstructor("You have received a friend request!")
        .includesColor(ChatColor.AQUA)
        .addText(" Click to show the request.")
        .includesColor(ChatColor.GRAY)
        .includesHoverTextEvent("§7Click me§8!")
        .includesClickEvent(ClickEvent.RUN_COMMAND, "/friend requestlist")
        .send(player);

I will add reflections soon!
