About BufferedReader

I am trying to build a mini webserver. The program below suppose to displayed the request of the client in the console, and wait for another connection...but it seems to block at
sContent = sockInput.readLine();
it seems to me that I am not using a correct approach to print the entire request from the client to the console, reason maybe the bufferedreader will not return null if there is nothing to read and simply will block there. Am I right?

What is the correction approach to display the request of the client to the console(by using bufferedreader) and not blocking at the middle if there is nothing to read?

public class Test {
      public static void main(String args[]) throws Exception {

            ServerSocket serverSocket = new ServerSocket(10000);
            while (true) {
                  Socket sock = serverSocket.accept();//Wait for connection
                  BufferedReader sockInput = new BufferedReader(
                              new InputStreamReader(sock.getInputStream()));
                  String sContent = sockInput.readLine();
                  while (sContent != null) {
                        System.out.println("here="+sContent);
                        sContent = sockInput.readLine();//<--Block here
                  }
                  
                  sock.close();
            }
      }
}
