這篇文章主要為大家詳細(xì)介紹了Java實(shí)現(xiàn)航空航班管理系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Java實(shí)現(xiàn)航空航班管理系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

Plane對(duì)象：

在Plane對(duì)象里定義了飛機(jī)的編號(hào)id、航班號(hào)、目的地、起飛日期。生成了構(gòu)造方法和toString()方法；以及getting()和setting()方法，但在程序里沒(méi)用到。

package com.hangkong;

public class Plane {
 
 private int id;//編號(hào)
 private String planeNum;//航班號(hào)
 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航班編號(hào):" + planeNum + "\t目的地:" + address + "\t起飛時(shí)間:" + date;
 }
}

MySQL數(shù)據(jù)庫(kù)：

數(shù)據(jù)庫(kù)名字是Fly，數(shù)據(jù)表是plane；在getcon()函數(shù)中注冊(cè)驅(qū)動(dòng)、獲取連接

主程序TestFly:

TestFly類中有實(shí)現(xiàn)各種功能的函數(shù)，包括 1.列出所有航班，2.按起飛時(shí)間查詢，3.按目的地查詢，4.刪除航班，5.更新航班，6.增加航班，7.退出系統(tǒng)。
