在android編程的學習中，遇到壹點關於Socket編程上的問題

看代碼，好像ServerSocket和Socket用錯了。

ServerSocket

public?static?void?main(String[]?args)throws?IOException{

ServerSocket?server=new?ServerSocket(9999);

Socket?clientconn=server.accept();

PrintWriter?out=new?PrintWriter(clientconn.getOutputStream(),true);

out.println("this?is?a?socket?test");

server.close();

clientconn.close();

}

}

client端

public?static?void?mian(String?args[])throws?IOException?{

Socket?client=new?Socket("localhost",9999);

BufferedReader?in=new?BufferedReader(new?InputStreamReader(client.getInputStream()));

System.out.println(in.readLine());

in.close();

client.close();

}

}
