2. A palindrome integer is one that "reads the same" from left to right and from right to left. So, for instance: 121, 12321 and 737 are all palindrome integers. Write a Java program that prompts a user to enter a 3-digit positive integer and determines whether it is a palindrome. Include the output of testing your code on the following input values: 171, 173, 747, 905 and 007. Integers with either more or fewer than 3 digits should be rejected, and the user should be prompted to try again and enter exactly three digits
