Solved Some Java OOP stuff problems

This is kind of a java question but the problem is to do with bukkit (wanted to just say that).

So, I have been coding java for idk like a year now and I know pretty much 5 - 6/7 stuff of java, and I only really do making small apps and bukkit / forge mods and plugins. I never do any Java OOP stuff, and I just want to ask about a problem Im having. EDIT: I have done a bit of java oop outside of bukkit API and it worked which was some time ago.

the following code below is coming out with a error, which is that the console outputs: "Successfully Loaded House Type : null.

Code:

public class HouseType {
 
    private String typeName = null;
 
    private List<Building> contents = new ArrayList<Building>();
 
    public HouseType(List<Building> contents, String typeName) {
        contents = this.contents;
        typeName = this.typeName;
     
        PixelCraftAPI.sendConsoleMessage(ChatColor.GREEN + "Successfully Loaded House Type : " + this.typeName);
     
    }
 
    public int getAmountOfBuildings() {
        return contents.size();
    }
 
    public List<Building> getContents(){
        return contents;
    }
 
    public String getTypeName() {
        return typeName;
    }

}

I have no idea why this is, and I have tried using typeName aswell as this.typeName. Any ideas?
