Write the following two programs:
Extend the multi-threading Java program to accept a number from the user at any moment, the program should also display the total of entered numbers so far every 2 seconds, and display the product of input numbers so far once every 3 seconds. The Java program should use at least 3 threads.
Multi-threaded shared data
Main.java

screenUpdaterTh.start();
inputReaderTh.start();
}
}
/*
Write a program that contineously accepts input
from the user and prints a name on the screen
every 1 min.

Input Reader
public class InputReader implements Runnable {
private BusinessLogic businessLogic;

while (true) {

Change the screen updater to display the number that has
been entered by the user.
