Explanation:

We will be creating 5 different projects in our eclipse or NetBeans IDE

We will be using the microservices principle in java

Create a new project called client1

inside the src folder, create the following java class

Client1.java

package client1;    import java.io.*;  import java.net.*;  import java.util.Scanner;  public class Client1 {  public static void main(String argv[]) throws Exception  {  long startTime = System.currentTimeMillis();  String ip = "localhost";  int port = 9999;  Socket s = new Socket(ip,port);    System.out.println("Server Connected...");  System.out.print("\nEnter the range : ");  Scanner sc = new Scanner(System.in);  int range = sc.nextInt();  System.out.println();  System.out.println("Data from Load Balance Server in Client 1 is: ");          for(int i=1;i<=range;i++)          {              int flag=0;              for(int j=2;j 

 
Create a new project called client2
 
inside the src folder, create the following java class
 
Client2.java
