Write a Java program using Nested Loops to print the factorials of all numbers between a range of two integers namely first and second. The first/second integers can be zero or any positive numbers and the first should be always less than or equal to second. Appropriate error message should be displayed in case of invalid inputs.

Validating User Input Summary In this lab, you will make additions to a Java program that is provided. The program is a guessing game. A random number between 1 and 10 is generated in the program. The user enters a number between 1 and 10, trying to guess the correct number. If the user guesses correctly, the program congratulates the user, and then the loop that controls guessing numbers exits; otherwise, the program asks the user if he or she wants to guess again. If the user enters a "Y", he or she can guess again. If the user enters "N", the loop exits. You can see that the "Y" or an "N" is the sentinel value that controls the loop. Note that the entire program has been written for you. You need to add code that validates correct input, which is "Y" or "N", when the user is asked if he or she wants to guess a number, and a number in the range of 1 through 10 when the user is asked to guess a number. Instructions Ensure the file named GuessNumber.java is open. Write loops…
