我是 JAVA 编程的新手，我在 JAVA INHERITANCE TOPIC [重复]中遇到了这个问题

Question

我有四个班级

1. 车主
2. 车辆
3. 轻型机动车
4. 重型机动车

我要接受n辆车的信息 并以适当的形式显示信息。在获取数据时，询问用户有关 首先是车辆类型。

VEHICLEMAIN.JAVA

package InheritanceAssignment;
import InheritanceAssignment2.*;
import java.util.Scanner;
public class VehicleMain {

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    System.out.println("How many no of vehicle details you wants to store");
    int no_of_vehicles = sc.nextInt();
    int count =0;
    while(no_of_vehicles --> 0) {
        System.out.println("Enter choice of vehicle for vehicle: "+count);
        System.out.println("1------> Light Motor Vehicle");
        System.out.println("2------> Heavy Motor Vehicle");
        Scanner ch = new Scanner(System.in);
        int choice = ch.nextInt();
        Vehicle r = null;
        switch(choice) {
        case 1:
            r = new LightMotorVehicle();
            break;
        case 2:
            r = new HeavyMotorVehicle();
            break;
        default:System.out.println("Wrong Choice");
        }
        r.input_details();
        r.display_details();
        
        count = count + 1;
        
    }
       sc.close();
}

}

VEHICLE.JAVA

package InheritanceAssignment2;
import java.util.Scanner;
public class Vehicle {
String company;
double price;   
public void input_details() {
    Scanner sc = new Scanner(System.in);
    System.out.println("Enter company Name");
    company = sc.next();
    
    System.out.println("Enter Price");
    price = sc.nextDouble();
    sc.close();
}
public void display_details() {
    
}

}

LIGHTMOTORVEHICLE.JAVA

package InheritanceAssignment2;

public class LightMotorVehicle extends Vehicle{
int mileage;
final static String vehicle_type = "Light";
void display_details_light_motor() {
    System.out.println("Vehicle Type: "+vehicle_type);
    System.out.println("Mileage: "+mileage);
 }
}

HEAVYMOTORVEHICLE.JAVA

package InheritanceAssignment2;

public class HeavyMotorVehicle extends Vehicle{
double capacity_in_tons;
final static String vehicle_type = "Heavy";
void display_details_light_motor() {
    System.out.println("Vehicle Type: "+vehicle_type);
    System.out.println("Capacity In Tons: "+capacity_in_tons);
   }
}
