Question

所以我尝试了解Socket和DataInputStream。

当我尝试尝试时，我意识到DataInputStream读取字符串是分开的，意思是这样的：

客户端：

dos = new DataOutputStream(socket.getOutputStream());

String msg = "okay test some String"

dos.writeUTF(msg);

服务器端：

dis = new DataInputStream(socket.getInputStream());

while(true){

    msg = dis.readUTF();

    Syso(msg);

}

结果：

okay

test

some

String

我想在一行中完整阅读msg。我该怎么办？

Answer 1

使用BufferedReader

dis = new BufferedReader(new InputStreamReader(socket.getInputs()))
while(true){
   msg = dis.readLine() 
   System.out.println(msg);
}

或者您可以将System.out.println替换为System.out.print，而dis = new DataInputStream(socket.getInputStream()); while(true){ msg = dis.readUTF(); System.out.print(msg+" "); }不会在最后打印新的换行符

java，为什么DataInputStream在whitespace时拆分String
