这段代码无法输出是因为它没有被调用，即没有在其他方法中被调用。您需要在其他方法中调用该方法才能执行其中的代码并输出结果。例如，您可以在主方法中调用该方法，如下所示：

public static void main(String[] args) {
    Scanner user = new Scanner(System.in);
    deleteRoom(user); // 调用删除房间方法
}

这样就可以执行 `deleteRoom()` 方法中的代码并输出结果。当然，您也可以在其他方法中调用该方法，具体取决于您的程序逻辑。

帮我用Java编写一个简单的旅店管理系统

好的，以下是一个简单的旅店管理系统的Java代码示例。

这个系统包含两个功能：客房管理和顾客管理。

客房管理包括添加客房、删除客房、查询客房信息等；顾客管理包括添加顾客、删除顾客、查询顾客信息等。

import java.util.ArrayList;
import java.util.Scanner;

public class HotelManagementSystem {

酒店管理系统房间管理网页设计加上增删改查js详细代码

酒店管理系统中，房间管理的网页设计通常涉及到前端的HTML、CSS以及JavaScript交互部分。这里是一个简单的示例，展示如何使用JavaScript实现基本的增删改查操作：

1. HTML结构 (创建页面布局):

<!DOCTYPE html>
<html lang="zh">
<head>
    <title>酒店房间管理</title>
</head>
<body>
    <h2>房间列表</h2>
    <table id="roomTable">
        <!-- 表格行将动态添加 -->
    </table>
    <button onclick="addRoom()">新增房间</button>
    <form id="editForm">
        <input type="hidden" id="roomId">
        <label for="roomName">房间名称:</label>
        <input type="text" id="roomName" required>
        ... 其他房间信息输入字段 ...
        <button onclick="updateRoom()">保存修改</button>
    </form>
    <script src="roomManagement.js"></script>
</body>
</html>

2. JavaScript (房间管理函数) - roomManagement.js:

// 假设我们有一个数组模拟房间数据
var rooms = [];

// 添加房间函数
function addRoom() {
    var newRow = '<tr><td>' + prompt("请输入房间编号") + '</td><td>' + document.getElementById('roomName').value + '</td>...</tr>';
    document.getElementById('roomTable').innerHTML += newRow;
}

// 更新房间函数 (假设已获取到房间ID)
function updateRoom() {
    var roomId = document.getElementById('roomId').value;
    var index = rooms.findIndex(room => room.id === parseInt(roomId));
    if (index !== -1) {
        rooms[index].name = document.getElementById('roomName').value; // 修改房间名等属性
        displayRooms(); // 刷新显示
    } else {
        alert("房间不存在");
    }
}

// 删除房间函数 (同样需要房间ID)
function deleteRoom() {
    var roomId = prompt("请输入要删除的房间编号");
    rooms = rooms.filter(room => room.id !== parseInt(roomId));
    displayRooms();
}

// 显示房间列表
function displayRooms() {
    var tableBody = document.getElementById('roomTable').getElementsByTagName('tbody')[0];
    tableBody.innerHTML = '';
    rooms.forEach(room => {
        var row = `<tr><td>${room.id}</td><td>${room.name}</td>...</tr>`;
        tableBody.appendChild(document.createElement('tr').innerHTML = row);
    });
}

这只是一个基础的例子，实际项目中可能还需要后端的支持，例如通过AJAX请求向服务器发送增删改查操作并处理响应。
