Question

我是Java新手但越来越沉迷于上瘾。我创建了这些类：

Car car1 = new Car();
car1.model = "Toyota";
car1.price = 1500;

Car car2 = new Car();
car2.model = "Peugeot";
car2.price = 2600;

我用

计算了最高价格

      int maxprice=Math.max(car1.price, car2.price);

哪个是标致。

现在我要打印计算价格的模型：

System.out.println("The most expensive car is "+ ????);

这是问题所在。我无法弄清楚这里发生了什么。我认为这将是.getmodel或其他什么，但我无法获得任何工作。我提前感谢你的帮助。感谢。

Answer 1

不要直接指定汽车的名称和价格。使用此

public void setPrice(int price)
{
    this.price = price;
}
public void setName(String name)
{
    this.name= name;
}
public void getPrice()
{
    return price;
}
public void getName()
{
    return name;
}

另外要比较价格使用比较器

这是我最好的解决方案：

public class Main
{
    public static void main()
    {
        Car car1 = new Car();
        car1.setModel ( "Toyota" );
        car1.setPrice ( 1500 );

        Car car2 = new Car();
        car2.setModel ( "Peugeot" );
        car2.setPrice ( 2600 );

        int biggestPrice = Math.max ( car1.getPrice(), car2.getPrice() ) 

        String model = "";

        switch ( biggestPrice ) {
            case car1.getprice: 
                model = car1.getModel();
                break;
            case car2.getPrice: 
                model = car2.getModel();
                break;
            default: 
                assert false : "Got a number that should not be able to appear";
                System.out.println ( "ERROR!" );
                return;
        }

        System.out.println("The most expensive car is " + model); 
    }

    class Car
    {
        String model;
        int price;

        public Car () {}

        public Car ( String model, int price ) 
        {
            this.model = model;
            this.price = price; 
        }

        public void getModel ( )
        {
            return this.model;
        }

        public void setModel (String model )
        {
            this.model = model;
        }

        public void getPrice ( )
        {
            return this.price;
        }

        public void setPrice ( int price )
        {
            this.price = price;
        }
    }

}
