[英]Problem while sending a string from client to server in java
I have sent a String from client to server but when it receives to the server it doesn't print in the first time only in second time and don't know why. 我已经将字符串从客户端发送到服务器,但是当它接收到服务器时,它不会在第二次第一次打印,也不知道为什么。
Here is the code : 这是代码:
Client Side: 客户端:
String str = "40D32DBBE665";
while (str != null) {
out.writeUTF(str);
}
Server Side: 服务器端:
String st="";
while(in.readUTF()!=null){ // it gets into the loop in the first time
System.out.println("Test"); // in the first time it prints this line
st = in.readUTF();
System.out.println(st);
}
So how I can receive it in the first time. 因此,我如何在第一时间收到它。 Please help !!!
请帮忙 !!!
Thanks in advance :) 提前致谢 :)
while(in.readUTF()!=null){ // it gets into the loop in the first time
System.out.println("Test"); // in the first time it prints this line
st = in.readUTF();
should be 应该
while((st=in.readUTF())!=null){ // don't miss odd messages
System.out.println(st);
}
You are effectively reading twice before printing on the server. 在服务器上进行打印之前,实际上您已阅读两次。 Try this:
尝试这个:
while((st = in.readUTF())!=null){ // it gets into the loop in the first time
System.out.println(st);
}
