Socket Programming in Java

 

1) First open the two notepad.

A] In first notepad, type the code for  server side and save it as the same class name which you have provided in the code and with the extension .java

For Example, MyServer1.java

import java.io.*; import java.net.*; public class MyServer1 { public static void main(String[] args) { try { ServerSocket ss=new ServerSocket(6666); Socket s=ss.accept();//establishes connection DataInputStream dis=new DataInputStream(s.getInputStream()); String  str=(String)dis.readUTF(); System.out.println("message= "+str); System.out.println("message= "+str); System.out.println("message= "+str); ss.close(); } catch(Exception e) { System.out.println(e); } } }

B] In second notepad, type the code for the client side and save it as the  same class name which you have provided in the code and with the extension .java

For Example, MyClient1.java

import java.io.*; import java.net.*; public class MyClient1 { public static void main(String[] args) { try { Socket s=new Socket("localhost",6666); DataOutputStream dout=new DataOutputStream(s.getOutputStream()); dout.writeUTF("Hello Server"); dout.flush(); dout.close(); s.close(); } catch(Exception e) { System.out.println(e); } } }

2) Output for the code:-

A] Server-Side :

B] Client-Side :
