Java 如何持续与tcp服务器通信？
我有一个TCP客户端，它目前正在作为终端工作。所以我可以手动向服务器发送消息。但这只是为了测试 但我需要与tcp服务器进行连续通信。我有不同的片段来显示不同的数据。我要发送消息，这取决于片段。属于片段的消息总是相同的 例如： 如果片段1在GUI上处于活动状态：Message1、Answer1、M2、A2、M3、A3、M1、A1、M2、A2 如果片段2在GUI上处于活动状态：M5、A5、M6、A6、M7、A7、M5、A5 所以消息总是重复，服务器的答案将显示在GUI上 我该怎么做 TCP客户端的代码：Java 如何持续与tcp服务器通信？,java,android,sockets,tcp,Java,Android,Sockets,Tcp,我有一个TCP客户端，它目前正在作为终端工作。所以我可以手动向服务器发送消息。但这只是为了测试 但我需要与tcp服务器进行连续通信。我有不同的片段来显示不同的数据。我要发送消息，这取决于片段。属于片段的消息总是相同的 例如： 如果片段1在GUI上处于活动状态：Message1、Answer1、M2、A2、M3、A3、M1、A1、M2、A2 如果片段2在GUI上处于活动状态：M5、A5、M6、A6、M7、A7、M5、A5 所以消息总是重复，服务器的答案将显示在GUI上 我该怎么做 TCP客户端的代

你能先解释一下你现在有哪些问题吗？为什么此代码不适用于您？
需要与tcp服务器持续通信。
