创建一个车辆基类 并包含属性 在创建car和bicyle继承属性 调用相关方法并展示信息

当然，首先我们创建一个简单的`Vehicle`基类，包含通用的属性如`name`和`color`，以及一个抽象的方法`drive()`，表示所有车辆都能行驶。然后我们会为`Car`和`Bicycle`这两个子类提供具体的实现。

// 车辆基类
public abstract class Vehicle {
    private String name;
    private String color;

    // 构造函数
    public Vehicle(String name, String color) {
        this.name = name;
        this.color = color;
    }

    // 获取属性的方法
    public String getName() {
        return name;
    }

    public String getColor() {
        return color;
    }

    // 抽象方法 drive()
    public abstract void drive();
    
    // 显示信息的方法
    public void displayInfo() {
        System.out.println("Name: " + name);
        System.out.println("Color: " + color);
        System.out.println("This is a vehicle.");
    }
}

// Car 子类
public class Car extends Vehicle {
    private int numDoors;

    public Car(String name, String color, int numDoors) {
        super(name, color);
        this.numDoors = numDoors;
    }

    @Override
    public void drive() {
        System.out.println(getName() + " is driving with " + numDoors + " doors.");
    }
}

// Bicycle 子类
public class Bicycle extends Vehicle {
    private boolean hasBasket;

    public Bicycle(String name, String color, boolean hasBasket) {
        super(name, color);
        this.hasBasket = hasBasket;
    }

    @Override
    public void drive() {
        System.out.println(getName() + " is cycling.");
    }
}

现在我们可以创建这些类的对象并调用相关方法：

public static void main(String[] args) {
    Car car = new Car("Toyota Camry", "Blue", 4);
    car.drive(); // 输出: Toyota Camry is driving with 4 doors.
    car.displayInfo();

    Bicycle bike = new Bicycle("Giant", "Red", true);
    bike.drive(); // 输出: Giant is cycling.
    bike.displayInfo();
}
