一個銷售員（信息包括姓名年齡），銷售車輛（車輛包含品牌和價格，多輛銷售），打印銷售員銷售多輛汽車的詳細報表（包含提成），提成為百分之零點五。

銷售員Seller.java

• 思路，銷售員肯定要定義一個姓名變量，一個年齡變量，一個提成變量。
• 肯定要有提成計算方法和輸出打印方法。
• 多輛銷售需要一個車輛數(shù)組。

package javaDemo2;

import java.util.Arrays;

public class Seller {
    String name;
    int age;
    public Car[] car;
    double salary;
    
    public double getSalary() {//獲取提成方法
        int totalPrice = 0;
        for(int i = 0; i < this.car.length; i++) {
            totalPrice+= this.car[i].price;
        }
        return totalPrice*0.05;
    }
    public void setSalary(double salary) {
        this.salary = salary;
    }  
    public Seller(String name, int age, Car[] car) {//構(gòu)造方法

public class Constructor {

    public static void main(String[] args) {
        
        Car c1 = new Car("法拉利Ferrari", 2000000);
        Car c2 = new Car("蘭博基尼Lamborghini", 3000000);
        Car[] cars = {c1, c2};
        Seller sellerA = new Seller("張三", 18, cars);
        System.out.println(sellerA);
        
        // forEach循環(huán)
        System.out.println("forEach循環(huán)打?。?);
        for(Car a : cars) {
            System.out.println(a);
        }
