This slide is about socket programming in java. Here I have tried to explain all the basic things of java socket programmnig.

3. WHAT IS SOCKET PROGRAMMING
 Socket programming is a way of connecting two nodes on a
network to communicate with each other.
 One socket (node) listens on a particular port at an IP, while
other socket reaches out to the other in order to form a connection.

4.  A socket is one endpoint of a
two-way communication link
between two programs running on
different computers on a network.
 A socket is bound to a port
number so that the transport layer
can identify the application that
data is destined to be sent to.
HOW IT WORKS

5.  There are mainly two parts in
socket programming~
 Server Side
 Client side
PART OF SOCKET PROGRAMMING

6.  ServerSocket(port)
 accept()
 InputStreamReader()
 BufferedReader ()
 Socket(“IP/localhost”, port)
 PrintWriter()
 getOutputStream()
 flush()

Server Side Client Side

7. ADVANTAGE OF SOCK E T PROGRAMMING
 Socket programming usually pertains to the basic communication
protocols like TCP/UDP and raw sockets like ICMP.
 Sockets are flexible and sufficient, can be easily implemented for
general communications.
 Only updated information can be sent, unlike HTML forms and CGI
scripts that generate and transfer whole web pages for each
new request, Java applets can send only necessary updated information.
 Cause low network traffic if efficiently used.

8. import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Scanner;
public class SocketProgramServerIntro
{
public static void main(String[] args)
throws IOException {
ServerSocket ss=new
ServerSocket(6010);
LIVE EXAMPLE (SERVER SIDE)
Socket s=ss.accept();
System.out.println("Clinet is connected");
InputStreamReader in =new
InputStreamReader(s.getInputStream());
BufferedReader bf= new
BufferedReader(in);
String str=bf.readLine();
System.out.println(str);
}
}

9. LIVE EXAMPLE (CLIENT SIDE)
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;
public class SocketProgramClientIntro {
public static void main(String[] args) throws IOException {
Socket s= new Socket("localhost",6010);
PrintWriter pr= new PrintWriter(s.getOutputStream());
pr.println(“Massage from client”); pr.flush(); } }
