Write a Java program that reads in a single digit number (-9 to 9 including zero) from the user at the keyboard into an integer variable. Your program will then print the number spelled out. If the user types in a number that is more than one digit, your program must print an error message. If the user types in a negative number, your program should print the word "negative" before the digit spelled out. Examples: Input 8 output will be Eight. Input -9 output Negative Nine. Input 0 output Zero. Input 11 output Error.
