Students have asked these similar questions
(1) Prompt the user for a string that contains two strings separated by a comma.
Examples of strings that can be accepted:
Jill, Allen
Jill , Allen
Jill,Allen
Ex:
Enter input string: Jill, Allen
(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. Ex:
Enter input string: Jill Allen Error: No comma in string Enter input string: Jill, Allen
(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. Ex:
Enter input string: Jill, Allen First word: Jill Second word: Allen
(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. Ex:
Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second word: Monkey Enter input string:…

Assignment: Carefully read the instructions and write a program that prompts the user to
enter a string and displays the number of vowels and consonants in the string. Assume letters
A, E, I, O, U (or a, e, i, o, u) as the vowels.
1. Prompt the user for a String. (Note: The user input String may contain spaces)
2. Print the number of vowels and consonants in the String. The count displayed must
account for all the vowels and consonants in the String regardless of case (upper or
lower case). You must use a loop in your solution.
Hint: charAt (index) and length () method for the String, toUpperCase (ch) (or
toLowerCase (ch)), isLetter (ch) method for the Character is helpful for this
assignment
3. The output from the program must be enclosed in quotes as shown below in the sample
run of the program.
Two Sample Run:
Enter a string: JAcgaeIOU 123 YRE!
"The number of vowels is 7"
"The number of consonants is 5"
Enter a string: 12345 67890
"The number of vowels is e"
"The number of…
