Java 我的客户机服务器套接字有问题，我对代码进行了编程，但当我将信息（作为客户机）输入控制台时，仍然没有发生任何事情

所以我面临的问题是，当我运行客户端并输入时，我按enter键什么都没有发生，它继续向下滚动，客户端必须输入信息，然后将其发送到服务器，服务器接收信息并将其添加到linkedlist，linkedlist在服务器类中初始化，之后，服务器执行CalculateShippingPrice并将包含价格的输出发送回客户端

类客户端

类服务器

代码中似乎有一些问题可以通过使用调试器来解决。一个问题是客户端正在收集和发送四行输入，而服务器只读取一行输入。我猜您可能想阅读服务器中的所有四行并删除ClientSession

name=informclient.readLine； ItemWeight=inFromClient.readLine PickUpLocation=infomclient.readLine DistnationLocation=infomclient.readLine 此外，响应必须写入新行，否则缓冲区将不会刷新。这可以通过在服务器中添加新行来解决：

outToClient.WriteByteCapitalizedEntence+'\n'；

使用调试器找出什么都没有发生的原因。public static void mainString argv[]引发异常-可能尝试捕获异常
