Sockets in nach0s
- 1. SOCKETS IN NACH0S Socket types: STREAM- Uses TCP which is realiable, stream oriented protocol.
- 2. RAW- Provides RAW data transfer directly over IP protocol.
- 3. DATAGRAM- Message oriented protocol.
- 4. SOCKETS IN NACH0S Socket use: Unicast
- 5. Multicast
- 6. Broadcast
- 7. Loopback
- 8. SOCKETS IN NACH0S Programming Client-Servidor in JAVA All the class located in the java.net package.
- 9. Stream classes are in the java.io package.
- 10. SOCKETS IN NACHOS How open a socket? For programming a client, create an object of Socket class. Socket Client; try { Client = new Socket("Machine name", PortNumber); } catch (IOException e) { System.out.println(e); }
- 11. SOCKETS IN NACH0S For programinng a server, in this part how you open a socket. ServerSocket Service; try { Service = new ServerSocket (PortNumber); } catch (IOException e) { System.out.println(e); }
- 12. When implementing a server you also need create a socket object. Socket clientSocket = null; try { clientSocket = Service.accept(); } catch (IOException e) { System.out.println(e); } SOCKETS IN NACH0S
- 13. SOCKETS IN NACH0S How to create an imput Stream ? You can use the DataImputStream class . DataInputStream input; try { input = new DataInputStream (Client.getInputStream()); } catch (IOException e) { System.out.println(e); }
- 14. SOCKETS IN NACH0S How to create an output Stream ? To the server socket using the class PrintStream or DataoutputStream of java.io PrintStream output; try { output = new PrintStream (Client.getOutputStream()); } catch (IOException e) { System.out.println(e); }
- 15. SOCKETS IN NACH0S How to close socket? You should always close the output and input stream before you close the socket. try { output.close (); input.close (); Client.close(); } catch (IOException e) { System.out.println(e); }
