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:

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

SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for `plane`-- ----------------------------DROP TABLE IF EXISTS `plane`;CREATE TABLE `plane` (  `id` int(20) NOT NULL AUTO_INCREMENT,  `planeNum` varchar(20) DEFAULT NULL,  `address` varchar(20) DEFAULT NULL,  `date` varchar(20) DEFAULT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;-- ------------------------------ Records of plane-- ----------------------------INSERT INTO `plane` VALUES (\'1\', \'DZ001\', \'东京\', \'2019-9-1\');INSERT INTO `plane` VALUES (\'2\', \'DZ002\', \'上海\', \'2019-8-28\');INSERT INTO `plane` VALUES (\'3\', \'DZ003\', \'广州\', \'2019-8-29\');INSERT INTO `plane` VALUES (\'4\', \'DZ004\', \'深圳\', \'2019-8-29\');INSERT INTO `plane` VALUES (\'5\', \'DZ005\', \'厦门\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'6\', \'DZ006\', \'杭州\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'7\', \'DZ007\', \'武汉\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'8\', \'DZ008\', \'成都\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'9\', \'DZ009\', \'西安\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'10\', \'DZ0010\', \'郑州\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'11\', \'DZ0011\', \'长沙\', \'2019-8-30\');INSERT INTO `plane` VALUES (\'12\', \'DZ0012\', \'民权\', \'2019-8-31\');INSERT INTO `plane` VALUES (\'13\', \'DZ0013\', \'莫斯科\', \'2019-9-1\');INSERT INTO `plane` VALUES (\'14\', \'DZ0014\', \'曼谷\', \'2019-9-2\');INSERT INTO `plane` VALUES (\'15\', \'DZ0015\', \'阿布扎比\', \'2019-9-2\');

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。
