Java 客户端-服务器从文件发送文本
Java Client-Server Sending Text From File
我是Java的新手，我的class被分配了任务：
设计一个 client/server 应用程序，其中客户端直接与服务器通信。服务器将产品和客户信息存储在两个单独的文件中。客户端应用程序将允许用户从服务器请求产品和客户信息。服务器将检索请求的信息并将其发送给客户端。信息将由客户端以用户友好的方式显示。建议您的应用程序使用 Swing 组件以支持用户友好的界面。
我以前没有构建过客户端-服务器应用程序。我按照 youtube 视频教程 (https://www.youtube.com/watch?v=vCDrGJWqR8w) 来构建客户端-服务器应用程序本身，但我不确定如何实现将文本文件中的信息从服务器发送到客户端。我在网上找不到答案，不知道是我问的方式不对还是怎么的。
我想我可以在服务器文件中添加 if 语句，所以当客户端输入相应的单词时，它会 运行 将特定文件的文本发送到客户端的代码。
如果有人能指导我如何完成此任务，我将不胜感激。我的导师没有回复我，这周末我们的辅导服务停止维护。
编辑：我找到了有关如何创建 GUI 的教程 (https://www.youtube.com/watch?v=h3i459_arng)。我决定编写 GUI 并添加文件读取功能可能更容易。
我还找到了一个关于如何从我的文件中读取文本的网站 (https://www.geeksforgeeks.org/different-ways-reading-text-file-java/)
现在我可以从文件中获取文本以写入服务器聊天中的 JTextArea window，但我需要将其发送到客户端聊天中的 JTextArea window。我该怎么做？

以防万一有人想知道，我想通了。我已经添加了 GUI，并找到了从 txt 文件中读取的代码，但我被卡住了，因为文件中的文本被添加到服务器的 GUI 中，我需要它添加到客户端的 GUI 中。
我需要使用我的 PrintWriter 对象编写器将文本发送到我的客户端。
这是我更新后的代码：
