Java中如何实现一个航空航班管理系统，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
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：
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

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。
