只有一个设置器的多个输入

Question

我希望您能帮助我完成一个学校项目。我正在编写一个代码，用户输入用户在橱柜中的食品杂货。它还指定了哪种产品，名称，购买的商店，标签，价格，数量 - 就像库存一样。我有一个类名称乳制品，可以为我需要的每个输入创建一个getter。这很好，我设置了它，有一个传递参数，当我在InputAry方法中调用Getter时，它可以正常工作。

但是，由于我问用户关于产品的很多问题，所以我不想拥有10个getters，只有一个方法可以拥有一个，然后传递参数？这里的代码是不工作的代码，我尝试将所有参数设置为一个getter，然后将参数仅一个一个一个。而且那行不通。这是可能的还是我必须为我提出的每个问题设置一个getter？

public static void InputDairy (Dairy DairyProducts[], Fruit FruitProducts[], Scanner input){ // START OF INPUT DAIRY
     System.out.println("Let's put in some DAIRY products");
     for (int i = 0; i < DairyProducts.length; i++){
         System.out.println("Enter name of DIARY product");
         String a = input.next();
         DairyProducts[i].setDairyData(a);
         System.out.println("Enter Store where you bought DIARY product");
         String a = input.next();
         DairyProducts[i].setDairyData(b);
         System.out.println("Enter how much you paid for DIARY product");
         String a = input.next();
         DairyProducts[i].setDairyData(c);
         System.out.println("Enter when did you buy DIARY product");
         String a = input.next();
         DairyProducts[i].setDairyData(d);
   }
} // END OF INPUT DAIRY enter code here

public class Dairy {
    private String D_NameOfDairy;
    private String D_NameOfStore;
    private int D_PricePaid;
    private int D_DayPurchased;
    private int D_BestBefore;
    private int D_AmountInGrams;
    private int D_Pieces;
    public Dairy () {
        D_NameOfDairy = "Default name of dairy";
        D_NameOfStore = "Default name of store for dairy";
        D_PricePaid = 0;
        D_DayPurchased = 01/01/2000;
        D_BestBefore = 10/10/2010;
        D_AmountInGrams = 0;
        D_Pieces = 0;
    }
    public void setDairyData (String a, String b, int c, int d){
        D_NameOfDairy = a;
        D_NameOfStore = b;
        D_PricePaid = c;
        D_DayPurchased = d;
    }
}

首先从用户那里获取所有答案，然后将它们传递给您的二线功能。

public static void InputDairy (Dairy DairyProducts[], Fruit FruitProducts[], Scanner input){ 
     System.out.println("Let's put in some DAIRY products");
     for (int i = 0; i < DairyProducts.length; i++){
         System.out.println("Enter name of DIARY product");
         String a = input.next();
         System.out.println("Enter Store where you bought DIARY product");
         String b = input.next();
         System.out.println("Enter how much you paid for DIARY product");
         String c = input.next();
         System.out.println("Enter when did you buy DIARY product");
         String d= input.next();
         DairyProducts[i].setDairyData(a,b,c,d);
   }
}
