A palindrome is a sequence of characters that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554, and 11611. Write an application called Palindrome.java that asks the user to enter in a five-digit integer and determines whether it is a palindrome. If the number is not five digits long, display an error message dialog indicating the problem to the user. When the user dismisses the error dialog, allow the user to enter a new value.
Your program will have the following four methods
main() method, which controls the execution of the program;
retrieveInput() method, which prompts and retrieves the input values;
check() method, which determines whether it is a palindrome; and
display() method, which displays the result.
