完善下列代码class MobileShop { 【代码1】 //用内部类InnerPurchaseMoney声明对象purchaseMoney1 【代码2】 //用内部类InnerPurchaseMoney声明对象purchaseMoney2 private int mobileAmount; //手机的数量 MobileShop(){ 【代码3】 //创建价值为20000的purchaseMoney1 【代码4】 //创建价值为10000的purchaseMoney2 } void setMobileAmount(int m) { mobileAmount = m; } int getMobileAmount() { return mobileAmount; } class InnerPurchaseMoney { int moneyValue; InnerPurchaseMoney(int m) { moneyValue = m; } void buyMobile() { if(moneyValue>=20000) { mobileAmount = mobileAmount-6; System.out.println("用价值"+moneyValue+"的内部购物卷买了6部手机"); } else if(moneyValue<20000&&moneyValue>=10000) { mobileAmount = mobileAmount-3; System.out.println("用价值"+moneyValue+"的内部购物卷买了3部手机"); } } } }public class NewYear{ public static void main(String args[]) { MobileShop shop = new MobileShop(); shop.setMobileAmount(3

下面是完整代码，包括代码1、代码2、代码3和代码4：

class MobileShop {
    InnerPurchaseMoney purchaseMoney1; // 代码1：用内部类InnerPurchaseMoney声明对象purchaseMoney1
    InnerPurchaseMoney purchaseMoney2; // 代码2：用内部类InnerPurchaseMoney声明对象purchaseMoney2
    private int mobileAmount; // 手机的数量

    MobileShop() {
        purchaseMoney1 = new InnerPurchaseMoney(20000); // 代码3：创建价值为20000的purchaseMoney1
        purchaseMoney2 = new InnerPurchaseMoney(10000); // 代码4：创建价值为10000的purchaseMoney2
    }

    void setMobileAmount(int m) {
        mobileAmount = m;
    }

    int getMobileAmount() {
        return mobileAmount;
    }

    class InnerPurchaseMoney {
        int moneyValue;

        InnerPurchaseMoney(int m) {
            moneyValue = m;
        }

        void buyMobile() {
            if (moneyValue >= 20000) {
                mobileAmount = mobileAmount - 6;
                System.out.println("用价值" + moneyValue + "的内部购物卷买了6部手机");
            } else if (moneyValue < 20000 && moneyValue >= 10000) {
                mobileAmount = mobileAmount - 3;
                System.out.println("用价值" + moneyValue + "的内部购物卷买了3部手机");
            }
        }
    }
}

public class NewYear {
    public static void main(String args[]) {
        MobileShop shop = new MobileShop();
        shop.setMobileAmount(30);
        System.out.println("原始手机数量：" + shop.getMobileAmount());
        shop.purchaseMoney1.buyMobile();
        System.out.println("购买后手机数量：" + shop.getMobileAmount());
        shop.purchaseMoney2.buyMobile();
        System.out.println("购买后手机数量：" + shop.getMobileAmount());
    }
}

注：为了方便测试，在main函数中添加了一些代码来演示购买手机的过程。你可以根据实际需求修改。
