还是把全部代码贴出来吧！！ 
客户端没问题，关键是服务器的问题。OutputStream out = socket.getOutputStream(); 
                            PrintWriter pw=new PrintWriter(out,true); 
                                    pw.println("1"); 
这段代码已经是执行了，但是客户端收不到,如果把它放到while的前面又行

Answer 1

ServerSocket s = new ServerSocket(9527);
Socket s1 = s.accept(); 
OutputStream os = s1.getOutputStream();
DataOutputStream dos = new DataOutputStream(os);
dos.writeUTF("text");
这样写试试     仅供参考

Answer 2

OutputStream out = socket.getOutputStream(); 
                            PrintWriter pw=new PrintWriter(out,true); 
                                    pw.write("1"); 

Answer 3

那就在while外面定义。在while里面定义了，范围就只能在while里面。
更何况在while里面定义。每次循环就定义一个对象。这样不好。注意范围问题。

Answer 5

用DataOutputStream 这个流的UTF-8试试。以前我测试通过。
