java编写一个汽车类car，属性∶品牌，车长，颜色，价格，创建五个对象，捷达，宝马，劳斯莱斯，科鲁兹，迈锐宝

在Java中，我们可以创建一个名为`Car`的类来表示汽车，包含品牌、车长、颜色和价格等属性。下面是一个简单的例子：

public class Car {
    private String brand;
    private double length;
    private String color;
    private double price;

    // 构造函数
    public Car(String brand, double length, String color, double price) {
        this.brand = brand;
        this.length = length;
        this.color = color;
        this.price = price;
    }

    // 获取和设置属性的方法
    public String getBrand() { return brand; }
    public void setBrand(String brand) { this.brand = brand; }

    public double getLength() { return length; }
    public void setLength(double length) { this.length = length; }

    public String getColor() { return color; }
    public void setColor(String color) { this.color = color; }

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

    @Override
    public String toString() {
        return "Car{" +
                "brand='" + brand + '\'' +
                ", length=" + length +
                ", color='" + color + '\'' +
                ", price=" + price +
                '}';
    }
}

// 创建并初始化五个Car对象
public class Main {
    public static void main(String[] args) {
        Car jetta = new Car("捷达", 4.5, "蓝色", 100000);
        Car bimmer = new Car("宝马", 5.0, "白色", 600000);
        Car rollsRoyce = new Car("劳斯莱斯", 7.0, "黑色", 2000000);
        Car cruze = new Car("科鲁兹", 4.8, "银色", 300000);
        Car malibu = new Car("迈锐宝", 5.1, "灰色", 400000);

        System.out.println(jetta);
        System.out.println(bimmer);
        System.out.println(rollsRoyce);
        System.out.println(cruze);
        System.out.println(malibu);
    }
}

在这个例子中，我们首先定义了一个`Car`类，然后在`main`方法中创建了五个不同品牌的Car对象，并设置了它们的属性。最后通过`toString()`方法打印出每个对象的信息。
