java - 缺少返回语句错误，我不知道错误是什么

Question

这是代码，

class Car
{
    public static String owner;
    public static String car;
    public static Integer plate_num;
    public static String car_color;

    Car(String owner, String car_name, Integer num, String color)
    {
        owner = owner;
        car = car_name;
        plate_num = num;
        car_color = color;
    }

    Void display ()
    {
        System.out.println("The owner of the car is  "+ owner + "and Car model is " + car);

        System.out.println("The  car number is  "+ plate_num + "and Car color is " + car_color);
    } // ---> here is the error

    public static void main (String args[])
    {
        Car car1 = new Car("MAriam", "Mini Cooper", 124834, "Navey");

        car1.display()  ;

        //System.out.println("Y3es");
    }
}

这里有一个 Void 返回值。 Void 实际上是一个类。

要解决您的问题，您必须将其更改为小写的 void。
