java程序编写，显示水果的订购详情，定义一个带有参数的构造方法，这些参数用于存放产品，数量和价格

public class ShuiGuo{

private String chanpin;

private int number;

private float price;

public ShuiGuo(String chanpin,int number,float price){

this.chanpin = chanpin;

this.number = number ;

this.price = price;

}

//省略get.set方法

}

最后的需求没看懂。是说自己输入水果之后，在来取3种不同的吗

Q2: java超市管理系统源代码

只写个demo级的例程很好写，但用到生产环境中还得具体分析设计再编码。这种代码网上太多了内，你随便搜下就有了。

Q3: java超市计价系统代码

package entity;

public class Market {

private int id;//id

private int num;//数量

private String goods;//商品

private double price;//价格

public Market(int id, int num, String goods, double price) {

super();

this.id = id;

this.num = num;

this.goods = goods;

this.price = price;

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public int getNum() {

return num;

}

public void setNum(int num) {

this.num = num;

}

public String getGoods() {

return goods;

}

public void setGoods(String goods) {

this.goods = goods;

}

public double getPrice() {

return price;

}

public void setPrice(double price) {

this.price = price;

}

public double calc( ){

double sum=price*num;

System.out.println("您消费共计："+sum+"￥");

return sum;

}

package test;

import java.util.HashMap;

import java.util.Map;

import java.util.Scanner;

import entity.Market;

public class Test {

private static MapInteger,Market goods=new HashMapInteger, Market();

public static void main(String[] args) {

System.out.println("-------超市计价系统-------");

String goods1="可口可乐";

String goods2="爆米花";

String goods3="益达";

printTable("编号","商品","价格");

printTable("1",goods1,"3.0￥");

printTable("2",goods2,"5.0￥");

printTable("3",goods3,"10.0￥");

goods.put(1, new Market(1, 1, goods1, 3.0));

goods.put(3, new Market(3, 1, goods3, 10.0));

Scanner input = new Scanner(System.in);

System.out.println("请输入商品的编号:");

int num = input.nextInt();

System.out.println("请输入商品的数量");

int amount = input.nextInt();

Market market = goods.get(num);

market.setNum(amount);

market.calc();

}

private static void printTable(String row1,String row2,String row3 ) {

System.out.print(row1);

if (row2!="商品") {

}

//测试结果：

-------超市计价系统-------

编号商品价格

1 可口可乐 3.0￥

2 爆米花 5.0￥

3 益达 10.0￥

请输入商品的编号:

请输入商品的数量

您消费共计：50.0￥

Q4: java程序下拉列表设计

效果图

参考代码

import java.awt.event.*;

import java.util.Vector;

import javax.swing.*;

public class Demo extends JFrame implements ActionListener {

JButton btn;

VectorString vector=new VectorString();

JComboBoxString jcb;

public Demo() {

vector.add("公斤");

vector.add("每个");

vector.add("每盒");

JLabel jl = new JLabel("单位");

jcb = new JComboBoxString(vector);//可以传入一个数组或者一个Vector链表,对下拉框进行初始化

btn=new JButton("获取下拉框的文字");

btn.addActionListener(this);

JPanel jp = new JPanel();

jp.add(jl);

jp.add(jcb);

jp.add(btn);

add(jp);

setSize(300, 200);

setLocationRelativeTo(null);

setTitle("下拉框Demo");

setDefaultCloseOperation(EXIT_ON_CLOSE);

}

public static void main(String[] args) {

new Demo().setVisible(true);

}

@Override

public void actionPerformed(ActionEvent e) {

JOptionPane.showMessageDialog(this, (String)jcb.getSelectedItem());

}

Q5: 数据库如何用java写超市购物程序？

要使用Java编写超市购物程序，您需要使用Java数据库编程技术来连接到您的数据库并执行相关的数据库操作。在Java中，您可以使用JDBC（Java数据库连接）API来连接到数据库并执行SQL语句。例如，您可以使用JDBC API来执行以下操作：

创建数据库连接

执行增删改查（CRUD）操作

提交或回滚事务

执行存储过程和函数

查询数据库元数据

此外，您还可以使用Java的面向对象编程技术来封装数据库操作，以便更方便地在您的程序中使用。例如，您可以创建一个类来表示超市商品，并定义一些方法来执行商品的增删改查操作。这样，您就可以在程序中通过调用这些方法来简单地完成对数据库的操作，而不需要编写复杂的SQL语句。
