Using TCP/IP sockets, write a client-server java program to make the client send the file name and to make the server send back the contents of the requested file if present and Implement the above program using as message queues or FIFOs as IPC channels

				
					import java.util.*;
import java.net.*;
import java.io.*;
public class tcpserver 
{
public static void main(String[] args)
{
try
{
ServerSocket s=new ServerSocket(998);
System.out.println("Server Ready\nwaiting for connection .....");
Socket s1=s.accept();
DataOutputStream dos= new DataOutputStream(s1.getOutputStream());
DataInputStream dis= new DataInputStream(s1.getInputStream());
System.out.println(dis.readUTF());
String path= dis.readUTF();
System.out.println("Request Recieved");
try
 {
File myFile= new File(path);
Scanner scn=new Scanner(myFile);
String st=scn.nextLine();
st="The contents of the file is"+st;
while(scn.hasNextLine())
{
st=st+"\n"+scn.nextLine();
}
dos.writeUTF(st);
dos.close();
s1.close();
s.close();
scn.close();
}
catch(FileNotFoundException e)
{
 System.out.println("ERROR! FILE NOT FOUND");
 dos.writeUTF("ERROR! FILE NOT FOUND");
}
}
catch(IOException e)
{
System.out.println("IO:"+e.getMessage());
}
finally
{
System.out.println("Connection Terminated");
}
}
}
