14.3: More Sentences

• Write a program that allows a user to enter a sentence and then the position of two characters in the sentence.
• The program should then report whether the two characters are identical or different.
• When the two characters are identical, the program should display the message:

and are identical!

• Note that should be replaced with the characters from the String. See example output below for more information.
• When the two characters are different, the program should display the message:

and are unique characters.

• Note that should be replaced with the characters from the String. See example output below for more information.
• Name your program Sentences.java
• Your program must use a do-while loop to allow the user to enter a series of sentences, or "X" to exit.
  • The program should accept both lower and upper case "X" as an indication the user wishes to exit the program.
  • Please see example output below
• It should also verify that the user provides numerical input for the positions of the characters in the String.
  • Hint: Use a while loop and !input.nextInt() to check for input mismatch exception.
  • See Lesson 14 notes for a discussion on input mismatch exception
  • You will need two while loops, one for each input.nextInt() statement for the numeric location of each character in the String
• Important: Note that you will need to use input.nextLine() to account for the fact that the loop causes an input.nextInt() to come before an input.nextLine().
  • See lesson 14 notes regarding the problem that can occur when you use input.nextInt() before an input.nextLine()
• When your program runs identically to the example output below, submit it to Canvas.

Your output should look identical to the following, except user input will vary:

Welcome!
