    Instructions:
    1). Create two object of the String class.
    2). Ask the user to enter two String values.
    3). find out the length of the both string using the length method.
    4). convert both strings to uppercase and lowercase.
    5). use the compareTo method to see which string comes first in the alphabet, displaying appropriate messages on the outcome.
    6). use the charAt method to see what value is at the 4 position in the first string and what value is at the 2 position in the second string, displaying appropriate messages on the outcome.
    7). use the equals method to see if the two strings entered are equal, displaying appropriate messages on the outcome.
    8). use the concat method to concatenate the two strings together, displaying appropriate messages on the outcome.
    9). use the equalsIgnoreCase method to see if the two strings entered are equal, while ignoring the case of the strings, displaying appropriate messages on the outcome.
    10). use the trim method so it will ignore any spaces in the string and then display the trimmed string to the screen.                                                                      */
