Write a program in Java to count the words that end in vowels in given sentences:

1. Prompt the user for one string: userStr.

2. Print the number of words ending in vowels.

-A vowel is at the end of a word if there is not an alphabetic letter immediately following it.

-The method Character.isLetter() tests if a character is an alphabetic letter (A-Z, a-z). E.g. Character.isLetter('a') is true and Character.isLetter('.') is false.

-See the sample output for examples.

3. Convert the String userStr to an array of characters called userStrArray.

-This step is just one line of code:

-char[] userStrArray = userStr.toCharArray();

4. Repeat step 2, using the character array userStrArray instead of the String userStr, to count the number of words (in the array) ending in vowels.

-It will be the same number of words as the first one.

-Do not use userStr in step 4. Use only userStrArray.

-The goal is to practice using array syntax.

5. Ask the user for another string and, unless the string is "exit", repeat steps 2, 3, 4, 5.

-Steps 1, 2, 3, 4, 5 must execute at least once, even if the user enters "exit" for the first string.

-Only start checking for "exit" when the user enters the second string (and subsequent strings).

6. When the user enters "exit", display a message stating the total number of words ending in vowels (in all sentences combined).

The goals of this assignment are:

To compare the syntax for traversing a string to the syntax for traversing an array in Java.

To practice using loops, if statements, and switch statements.

To write clean, structured code, with easy-to-follow logic.

Sample output for clarification.
