java - 在另一个 JFrame 表单中获取一个 JFrame 表单的原始 boolean 类型的值？

Question

我使用 java swing 和 java-google-text-to-speech-api 设计了这个示例聊天应用程序，它允许您翻译语言。我试图在这个演示程序中实现的是单击选择按钮。选择按钮的文本必须首先更新为英语，然后更新为印地语，并相应地将标志变量 i 设置为 0 或 1。然后在服务器程序中使用 i 的这个值，我想弄清楚应该显示印地语消息还是英语消息。但是我无法做到这一点。我处理事件以实现此目的的方式是否有问题？ ？如果是，请给出解决方案。

此外，我面临的另一个问题是，一旦我从客户端向服务器发送消息，我就无法发送更多消息，直到重新运行程序。我该如何解决这个问题？？？

请在这方面提供帮助，如果您需要更多解释，请告诉我......

谢谢:)

Answer 1

很简单，使用 JcomboBoxes 选择语言并将该值传递给其他表单，然后设置首选语言。但是，在打包程序时请务必牢记访问修饰符概念。
