Java实现航空航班管理系统
本文实例为大家分享了Java实现航空航班管理系统的具体代码,供大家参考,具体内容如下
Plane对象:
在Plane对象里定义了飞机的编号id、航班号、目的地、起飞日期。生成了构造方法和toString()方法;以及getting()和setting()方法,但在程序里没用到。
package com.hangkong; public class Plane { private int id; //编号 private String planeNum; //航班号 private String address; //目的地 private String date; //日期 public Plane(int id, String planeNum, String address, String date) {super(); this.id = id; this.planeNum = planeNum; this.address = address; this.date = date; } public Plane(){super(); } //Alt+Shift+s public int getId() {return id; } public void setId(int id) {this.id = id; } public String getPlaneNum() {return planeNum; } public void setPlaneNum(String planeNum) {this.planeNum = planeNum; } public String getAddress() {return address; } public void setAddress(String address) {this.address = address; } public String getDate() {return date; } public void setDate(String date) {this.date = date; } @Override public String toString() {return "Plane" + id + "\t\t" + planeNum + "\t\t" + address + "\t\t" + date; //return "Plane ID:" + id + "\t航班编号:" + planeNum + "\t目的地:" + address + "\t起飞时间:" + date; }}
MySQL数据库:
【Java实现航空航班管理系统】数据库名字是Fly,数据表是plane;在getcon()函数中注册驱动、获取连接

主程序TestFly:
TestFly类中有实现各种功能的函数,包括 1.列出所有航班,2.按起飞时间查询,3.按目的地查询,4.删除航班,5.更新航班,6.增加航班,7.退出系统。
