//题目需求：定义数组存储3个汽车对象
//汽车的属性：品牌，价格，颜色
//创建三个汽车对象，数据通过键盘录入而来，并把数据存入到数组当中

1.标准的JavaBean类

public class Car {
    private String brand;//品牌
    private double price;//价格
    private String color;//颜色

    //空参
    public Car() {
    }

    //全参

    public Car(String brand, double price, String color) {
        this.brand = brand;
        this.price = price;
        this.color = color;
    }

    //成员方法

    public String getBrand() {
        return brand;
    }

    public void setBrand(String brand) {
        this.brand = brand;
    }

    public double getPrice() {
        return price;
    }

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

    public String getColor() {
        return color;
    }

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

2.测试类

import java.util.Scanner;

public class CarTest {
    public static void main(String[] args) {
        //1.定义一个数组来存储三个汽车对象
        Car arr[] = new Car[3];
        //2.创建汽车对象，用键盘录入
        Scanner sc = new Scanner(System.in);
        for (int i = 0; i < arr.length; i++) {

                //创建汽车对象
                Car c = new Car();
                //录入品牌
                System.out.println("请输入汽车的品牌：");
                String brand = sc.next();
                c.setBrand(brand);
                //价格
                System.out.println("请输入车的价格：");
                double price = sc.nextDouble();
                c.setPrice(price);
                //颜色
                System.out.println("请输入车的颜色：");
                String color = sc.next();
                c.setColor(color);
                //把汽车对象添加到数组中
                arr[i] = c;
            }


        //3.遍历输出
        for (int i = 0; i < arr.length; i++) {
            Car a = arr[i];
            System.out.println(a.getBrand() + ", " + a.getPrice() + ", " + a.getColor());
        }
    }
}

3.运行结果
