You must count both upper case and lower case ones). Users may enter Stringswith spaces such as "Looping is a powerful construct in programming languages.". Think about efficiency whendetermining if a character is a vowel (case insensitivity) by assuming you need to do the counting on stringscontaining Imillion of characters or so.Hint: To read individual characters in a String one can use the following methods that are available to String object:length () which return the total number of characters in the String and charAt ( index ) to get the character at indexlocation (0-based).For example:String message= new String ( "To BE or not to BE" );message.length () will return 18.message.charAt ( 0 ) returns 'T'.message,charAt ( 5 ) returns ' '.message,charAt ( 16 ) returns 'B'.The total vowels in message is : 6

Question

I need help writing a java code that counts vowel in a sentence MUST use while loop

• If users select 'C' or 'c' the program will count the number of vowels in a user input String (spaces included).
o ask users to enter a String to count for the vowels, then use a while loop to count the number of vowels occurrences
in the String (vowels are: a,e,i,0,u. You must count both upper case and lower case ones). Users may enter Strings
with spaces such as "Looping is a powerful construct in programming languages.". Think about efficiency when
determining if a character is a vowel (case insensitivity) by assuming you need to do the counting on strings
containing Imillion of characters or so.
Hint: To read individual characters in a String one can use the following methods that are available to String object:
length () which return the total number of characters in the String and charAt ( index ) to get the character at index
location (0-based).
For example:
String message
= new String ( "To BE or not to BE" );
message.length () will return 18.
message.charAt ( 0 ) returns 'T'.
message,charAt ( 5 ) returns ' '.
message,charAt ( 16 ) returns 'B'.
The total vowels in message is : 6

Learning Objectives: Python Programming Use loop over a stringReplace characters within a stringFunction (declaration and call)Write code in modular formInstructions Create a function only_chars that takes the line of text and returns the text line excluding the spaces, periods, exclamation points, or commas. Create a program that will read the input line, use the function, and then print the line, without spaces, periods, exclamation marks, or commas and their length.

Create the game of Hangman.In the game of Hangman, the computer chooses a word at random from a given list of words. This word is the answer. The player then tries to guess the word, by guessing one letter at a time. This program is an interactive Hangman game. The focus is to use and manipulate strings and loops. Whenever the user guesses a letter that is in the answer, all occurrences of that letter are revealed to the user.___ The game ends when the user has guessed every letter in the word, before he reaches the allowed number of strikes (usually 5).
