友友们，这四个代码怎么写呀

public class House {
    int price;
    int area;
    double rate;
    
    public void printTotalPrice(int price,int area){
        System.out.println("总价:"+price*area);
    }
    public void printShareArea(int area,double rate){
        System.out.println("公摊面积："+area*rate);
    }

    
    public static void main(String[] args) {
        House h = new House();
        h.printTotalPrice(12000, 100);
        h.printShareArea(100, 0.1);

    }

}
