java - Constructor Jeans 不能应用给定的类型

Question

我在 CodeHS 中工作，我收到此错误:类 Jeans 中的构造函数 Jeans 无法应用于给定类型；

我看过了，但找不到解决这个问题的方法。

我试过只使用父类(super class)中的一个参数，然后是所有参数，然后是所有参数再加上我创建的一个。牛仔裤必须是蓝色的，因此我只想说尺码。

这是父类(super class):

public class Clothing
{
    public String size;
    public String color;

    public Clothing(String size, String color)
    {
        this.size = size;
        this.color = color;
    }

    public String getSize()
    {
        return size;
    }

    public String getColor()
    {
        return color;
    }

    public String toString()
    {
        return "Clothing with size " + size + " and the color " + color;
    }
}

这是 Jeans 类:

public class Jeans extends Clothing
{

  public Jeans(String size)
  {
    super(size);
  }

  public String toString()
  {
    return "Blue jeans with size " + size;
  }
}

这是我正在测试的编码:

public class ClothingTester extends ConsoleProgram
{
    public void run()
    {
        Clothing myClothes = new Clothing("24", "grey");
        System.out.println(myClothes);
        Sweatshirt mySweatshirt = new Sweatshirt("24", "grey", true);
        System.out.println(mySweatshirt.getSize());
        TShirt myTShirt = new TShirt("24", "grey", "polyester");
        System.out.println(myTShirt);
        Jeans myJeans = new Jeans("24");
        System.out.println(myJeans);
    }
}

这是我必须使用父类(super class) Clothing 的另外两个子类(它们工作正常):

public class TShirt extends Clothing
{
    public String fabric;

    public TShirt(String size, String color, String fabric)
    {
        super(size, color);
        this.fabric = fabric;
    }

    public String getFabric()
    {
        return fabric;
    }

    public String toString()
    {
        return "T-shirt with size " + size + " and is the color " + color + " and is made of " + fabric;
    }
}

public class Sweatshirt extends Clothing
{
    public boolean hasHood;

    public Sweatshirt(String size, String color, boolean hasHood)
    {    
        super(size, color);
        this.hasHood = hasHood;
    }

    public boolean hasHood()
    {
        return hasHood;
    }

    public String toString()
    {
        return "Sweatshirt with size " + size + " and is the color " + color + ". Does it have a hood? " + hasHood;
    }
}

我希望 Jeans 输出尺寸(颜色应保持蓝色)，但我收到编译时错误。

您的 Jeans 类没有为父类(super class)提供 color 参数。

public Jeans(String size)
{
    /* Default color for Jeans is blue. */
    super(size, "blue");
}
