• Socket不断报错!!(记得 要加上,以及Socket上流通的是字节!还有Socket需要借助数据流来完成数据传递工作,注意输入流的导包不要导入错误,是io流包)


    Socket不断报错!!(记得 要加上,以及Socket上流通的是字节!还有Socket需要借助数据流来完成数据传递工作,注意输入流的导包不要导入错误,是io流包)

    1,在Socket 客户端上写入的是字节。

    错误代码:

     2,Socket 客户端写入请求指令要以 结尾(这里报错添加 后正确的根本原因:“引自评论者: 小新动感光波”:)

    【ps: 结束是因为你用了readLine,socket并没有强制要求你用 作为结尾。

     错误代码:

     

    3,io 流导错包了,快捷键ctr+shift +o 导的包可能是第一个位置的“import org.omg.CORBA.portable.InputStream;”

    ✌全部代码:
