Java Data Report Generation Code

During execution, the server starts with java test 1 and the client starts with java test. When the server type A character, the client prints the corresponding character, I hope the following code will be useful to you.

1. Import java.net .*;
2. Public class test {
3. Public static int serverPort = 666;
4. Public static int clientPort = 999;
5. Public static int buffer_size = 1024;
6. Public static DatagramSocket ds;
7. Public static byte buffer [] = new byte [buffer_size];
8. Public static void TheServer () throws Exception {
9. Int pos = 0;
10. While (true ){
11. Int c = System. in. read ();
12. Switch (c ){
13. Case:
14. Ds. send (new DatagramPacket (buffer, pos, InetAddress. getLocalHost (), clientPort ));
15. Pos = 0;
16. Break;
17. Default:
18. Buffer [pos] = (byte) c;
19. }
20. }
21. }
22. Public static void TheClient () throws Exception {
23. While (true ){
24. DatagramPacket p = new DatagramPacket (buffer, buffer. length );
25. Ds. receive (p );
26. System. out. println (new String (p. getData (), 0, p. getLength ()));
27. }
28. }
29. Public static void main (String [] args) throws Exception {
30. // TODO Auto-generated method stub
32. If (args. length = 1 ){
33. Ds = new DatagramSocket (serverPort );
34. TheServer ();
35. } Else {
36. Ds = new DatagramSocket (clientPort );
37. TheClient ();
38. }
39. }
40. }
