Java 实现旅游项目信息管理系统：增删改查全搞定！

```java import java.util.ArrayList; import java.util.List; import java.util.Scanner; // 旅游项目类 class Trip { private int tripid; // 项目编号 private String tripname; // 项目名称 private double tripprice; // 项目价格 private String detailinfo; // 详细信息 public Trip(int tripid, String tripname, double tripprice, String detailinfo) { this.tripid = tripid; this.tripname = tripname; this.tripprice = tripprice; this.detailinfo = detailinfo; } public int getTripid() { return tripid; } public void setTripid(int tripid) { this.tripid = tripid; } public String getTripname() { return tripname; } public void setTripname(String tripname) { this.tripname = tripname; } public double getTripprice() { return tripprice; } public void setTripprice(double tripprice) { this.tripprice = tripprice; } public String getDetailinfo() { return detailinfo; } public void setDetailinfo(String detailinfo) { this.detailinfo = detailinfo; } @Override public String toString() { return "Trip [tripid=" + tripid + ", tripname=" + tripname + ", tripprice=" + tripprice + ", detailinfo=" + detailinfo + "]"; } } public class TripManagement { private static List<Trip> tripList = new ArrayList<>(); public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int choice = -1; do { displayMenu(); System.out.println("请选择操作："); choice = scanner.nextInt(); switch (choice) { case 1: addTrip(scanner); break; case 2: queryTrip(scanner); break; case 3: updateTrip(scanner); break; case 4: deleteTrip(scanner); break; case 5: displayAllTrips(); break; case 0: System.out.println("感谢使用，再见！"); break; default: System.out.println("无效操作，请重新选择。"); break; } } while (choice != 0); scanner.close(); } // 展示菜单 private static void displayMenu() { System.out.println("-----------旅游项目信息管理系统-----------"); System.out.println("1、新增旅游项目信息"); System.out.println("2、查询旅游项目信息"); System.out.println("3、修改旅游项目信息"); System.out.println("4、删除旅游项目信息"); System.out.println("5、显示全部旅游项目信息"); System.out.println("0、退出系统"); System.out.println("----------------------------------------"); } // 新增旅游项目 private static void addTrip(Scanner scanner) { System.out.println("请输入项目编号："); int tripid = scanner.nextInt(); scanner.nextLine(); System.out.println("请输入项目名称："); String tripname = scanner.nextLine(); System.out.println("请输入项目价格："); double tripprice = scanner.nextDouble(); scanner.nextLine(); System.out.println("请输入详细信息："); String detailinfo = scanner.nextLine(); Trip trip = new Trip(tripid, tripname, tripprice, detailinfo); tripList.add(trip); System.out.println("新增旅游项目成功！"); } // 查询旅游项目 private static void queryTrip(Scanner scanner) { System.out.println("请输入要查询的项目编号："); int tripid = scanner.nextInt(); for (Trip trip : tripList) { if (trip.getTripid() == tripid) { System.out.println(trip); return; } } System.out.println("未找到该项目。"); } // 修改旅游项目 private static void updateTrip(Scanner scanner) { System.out.println("请输入要修改的项目编号："); int tripid = scanner.nextInt(); for (Trip trip : tripList) { if (trip.getTripid() == tripid) { System.out.println("请输入新的项目名称："); String tripname = scanner.nextLine(); scanner.nextLine(); // 清除缓冲区 System.out.println("请输入新的项目价格："); double tripprice = scanner.nextDouble(); scanner.nextLine(); System.out.println("请输入新的详细信息："); String detailinfo = scanner.nextLine(); trip.setTripname(tripname); trip.setTripprice(tripprice); trip.setDetailinfo(detailinfo); System.out.println("修改旅游项目成功！"); return; } } System.out.println("未找到该项目。"); } // 删除旅游项目 private static void deleteTrip(Scanner scanner) { System.out.println("请输入要删除的项目编号："); int tripid = scanner.nextInt(); for (int i = 0; i < tripList.size(); i++) { if (tripList.get(i).getTripid() == tripid) { tripList.remove(i); System.out.println("删除旅游项目成功！"); return; } } System.out.println("未找到该项目。"); } // 显示全部旅游项目信息 private static void displayAllTrips() { for (Trip trip : tripList) { System.out.println(trip); } } } ``` 以上是一个简单的旅游项目信息管理的实现思路，利用面向对象的思想定义了旅游项目类，并使用列表存储所有旅游项目信息。利用菜单展示页面，通过用户选择来实现新增、查询、修改、删除旅游项目信息的功能。通过函数来实现具体的操作逻辑。这样就可以实现一个基本的旅游项目信息管理系统。 ######[AI写代码神器 | 4014点数解答 | 2024-12-13 16:30:02]
