Program Plan Intro
Vowels and Consonants
Program Plan:
The details of “VowelConsCounter” class are shown below:
- In the “main()” method,
- Declare the required variable.
- Read the input from the user.
- Create an object for Scanner class.
- Create an object for VowelCons class.
- The do...while loop executes until “e” character. If yes,
- Get the user's selection and the assign into selection.
- Match the selection case is “a”. If yes, call getNumVowels() method to display number of vowels and exit the loop.
- Match the selection case is “b”. If yes, call getNumConsonants() method to display number of consonants and exit the loop.
- Match the selection case is “c”. If yes, call getNumVowels() and getNumConsonants() method to display number of vowels and consonants and exit the loop.
- Match the selection case is “d”. If yes, get another input from user.
- In the “getMenuSelection()” method,
- Declare the required variables.
- Create an object for Scanner class.
- Display the menus to user.
- Read the input selection from user.
- The while loop executes until the input choice. If yes,
- Display the error message.
- Return the user choice.
- The details of “VowelCons” class is shown below:
- Declare the variable to set a list of the vowels.
- Declare the variable to set a list of the consonants.
- Declare the required variables.
- Define the parameterized constructor to call countVowelsAndCons() method.
- Define the getNumVowels() method to return the number of vowels.
- Define the getNumConsonants() method to return the number of consonants.
- In the countVowelsAndCons() method,
- The for loop executes until the length of vowels. If yes, determine the character at position is equal to vowels.
- Check whether the character is not vowel. If yes, determine the character at position is equal to consonants.

Students have asked these similar questions
Vowels and Consonants Create an application with a method that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another method that accepts a string as an argument and returns the number of consonants that the string contains. The application should let the user enter a string, and should display the number of vowels and the number of consonants it contains.
True or False: The String class’s replace method can replace individual characters, but cannot replace substrings.
C sharp
Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise, it should return false.
