47.面向对象综合训练-汽车
//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()); } } }
