Multiple CLients, Single server, No threading

[FatimaMirza]

I am attempting to to run multiple clients with single server, without using athreading. My logic is as follows, use different port numbers for each client.
I have been successful in running a single server-single client system.
I am posting the code below.

How do I fix the code to incorporate multiple clients.

package tcpmsg;

import java.io.*;
import java.net.*;
class TCPClient
{
	public static void main(String argv[]) throws Exception
	{
		String sentence;
		String modifiedSentence;

		BufferedReader inFromUser=
			new BufferedReader(new InputStreamReader(System.in));

		InetAddress inetAddress=InetAddress.getLocalHost();
		//.getByName(String hostname); "CL11"
		System.out.println(inetAddress);

		Socket clientSocket = new Socket(inetAddress,6789);
		DataOutputStream outToServer=
			new  DataOutputStream(clientSocket.getOutputStream());

		BufferedReader inFromServer=
			new  BufferedReader(new InputStreamReader
							(clientSocket.getInputStream()));

		sentence=inFromUser.readLine();
		outToServer.writeBytes(sentence+'\n');

		modifiedSentence=inFromServer.readLine();
		System.out.println("From Server: "+modifiedSentence );
		clientSocket.close();
	}
}

import java.io.*;
import java.net.*;

class TCPServer
{
	public static void main(String argv[]) throws Exception
	{
		String clientSentence;
		String capitalizedSentence;
		ServerSocket welcomeSocket= new ServerSocket(6789);
		while (true)
		{
			Socket connectionSocket=welcomeSocket.accept();
			BufferedReader inFromClient=
				new BufferedReader(new InputStreamReader(
					connectionSocket.getInputStream()));
			DataOutputStream outToClient=
				new DataOutputStream(
					connectionSocket.getOutputStream());
			clientSentence=inFromClient.readLine();
			System.out.println("From Client: "+clientSentence);
			capitalizedSentence=
				clientSentence.toUpperCase()+'\n';

			outToClient.writeBytes(capitalizedSentence);
			
		}
	}
}
