我使用java swing和java谷歌文本到语音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点击选择按钮。选择按钮的文本必须首先更新为英语,然后更新为HINDI,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这个i值,我想弄清楚应该显示印地语消息还是英语消息。但我做不到。我处理事件以实现这一目标的方式有错吗???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,在重新运行程序之前,我无法发送更多消息。我该如何解决这个问题???
请在这方面帮忙,如果你需要更多的解释,请告诉我。。。。
谢谢:)

它很简单,使用JcomboBoxes来选择一种语言,并将该值传递给其他表单,然后设置首选语言。不过,在打包程序时,一定要记住访问修饰符的概念。
为什么不尝试使用JComboBox选择一种语言,然后在第二帧中使用该类的实例传递该选择索引:)
