从键盘输入的值 放到javabean 函数数组中

类

package com.fqs.demo1;

public class Car {
    private String pinpai;
    private Double price;
    private String color;
    public Car() {
        
    }
    public Car(String pinpai,Double price,String color) {
        this.pinpai=pinpai;
        this.price=price;
        this.color=color;
    }
    //set get pinpai;
    public void setPinpai(String pinpai) {
        this.pinpai=pinpai;
    }
    public String getPinpai() {
        return pinpai;
    }
    //set get price
    public void setPrice(Double price) {
        this.price=price;
        
    }
    public double getPrice() {
        return price;
    }
    //set get color
    public void setColor(String color) {
        this.color=color;
        
    }
    public String getColor() {
        return color;
    }

}

学习后的对象

package com.fqs.demo1;

import java.util.Scanner;

public class CarTest {
    public static void main(String[]args) {
        //1.创建一个数组用来存3个汽车的对象
        Car[]arr=new Car[3];
        //2.创建数据对象,数据来自于键盘录入
        Scanner s=new Scanner(System.in);
        
        for (int i=0;i<arr.length;i++) {
            //---首先,初始化对象
            Car c=new Car();
            System.out.println("第"+(i+1)+"次:");
            
            //1.1提示输入品牌
            System.out.println("品牌:");
            String pinpai=s.next();
            //1.2放品牌
            c.setPinpai(pinpai);
            
            //2.1提示输入价格
            System.out.println("价格:");
            double price=s.nextDouble();
            //2.2放价格
            c.setPrice(price);
            //3.1提示输入颜色
            System.out.println("颜色:");
            String color=s.next();
            //3.1提示输入颜色
            c.setColor(color);
            
            //----最后,将获取的值存到数组中
            arr[i]=c;
            
            
            
        }
        //3.输出结果
        for (int i=0;i<arr.length;i++) {
            Car c=arr[i];
            System.out.println(c.getPinpai()+" "+c.getPrice()+" "+c.getColor());
        }
        
        
                
    }

}

 

 

自己写的对象

package com.fqs.demo1;

import java.util.Scanner;

public class CarTest {
    public static void main(String[]args) {
        for (int i=0;i<3;i++) {
            System.out.println("第"+(i+1)+"次:");
            Scanner s=new Scanner(System.in);
            //提示输入品牌
            System.out.println("品牌:");
            String pinpai1=s.next();
            
            //提示输入价格
            System.out.println("价格:");
            double price1=s.nextDouble();
            
            //提示输入颜色
            System.out.println("颜色:");
            String color1=s.next();
            Car c=new Car(pinpai1,price1,color1);
            
            System.out.println(c.getPinpai()+" "+c.getPrice()+" "+c.getColor());
            
        }
        
        
        
        
                
    }

}
