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.

JAVAA7-Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned.
Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Sentence Capitalizer Create an application with a method that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argument is "hello. my name is Joe. what is your name?" the method should return the string "Hello. My name is Joe. What is your name?" The application should let the user enter a string and then pass it to the method. The modified string should be displayed.

- Complete the class LeetMaker class using String methods. Remember that all the String methods are accessors. They do not change the original String. If you want to apply multiple methods to a String, you will need to save the return value in a variable. Complete the class by doing the following: Print the word in lowercase Replace "e" with "3" (Use the unmodified variable word) Print the changed word In the changed word, replace: "t" with "7" Print the changed word In this newest changed word, replace: "L" with "1" (uppercase L with the number 1). Then, print the final changed word (with all the replacements) Print the length of the word The code to print the original word is already included for you. Do not change that statement. You will need to use the replace() method multiple times. Then print the final String. Remember that replace is an accessor method; It returns the changed version of the String.

- Pattern and Value are two strings that you must use. The pattern string, which denotes a pattern inside a string, is made up just of the letters a and b. For instance, the string catcatgocatgo matches the pattern aabab (where cat is represented by letter A and go by letter B). Additionally, it matches a, ab, and b pattern. To check whether a value matches a pattern, create a method.arrow_forwardC 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.arrow_forwardThe String class has several overloaded versions of a method that accepts a value of any primitive data type as its argument and returns a string representation of the value.

- Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."arrow_forwardpublic static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…arrow_forwardRepeating String Write a method that takes a String and an int and return a String that is the original String repeated n times.

Morse Code Converter Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes. Write a program that asks the user to enter a string, and then converts that string to Morse code and prints on the screen. Use hyphens for dashes and periods for dots. The Morse code table is given in a text file morse.txt. When printing morse code, display eight codes on each line except the last line. Codes should be separated from each other with one space. There should be no extra spaces at the beginning and at the end of the output. Uppercase and lowercase letters are translated the same way.

Considercapital and small letters variance. The gender should be “m” or “M” for male or “f” or “F” for female. The age should be a positive value. The giveRaise method increase the salary of a character by a given percentage with amaximum salary of 10000. The toString method returns a string that describes the character. For example: [Elisabeth Kane, female, 35, primary,4500$] 2) Implement the class Play A Play can have at most 20 characters. The real number of characters is registered in nbOfCharacters and is updated automaticallywhen a new character is added. AddCharacter method adds a new character to the characters array and updates thenbOfCharacters value. The attribute nbPlay keeps track of the number of Plays created. The toString method returns a string description of the play including name, genre and thenames of all the characters.Example: [The Opera…arrow_forward
