Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements:
Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters.
Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion.
Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion.
Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.
Write a java method:
public static String repeat(String str, int num)
that returns the string str repeated n times.
For Example: repeat("delta", 4) returns "deltadeltadeltadelta".
Given a string, write a method that returns the number of occurrences of substrings "baba" or "mama" in the input string recursively.
They may overlap.
Do not use any loops within your code.
Do not use any regular expressions and methods such as matches, split, replaceAll.

For simplicity, in this problem only the characters aeiouAEIOU are considered vowels, and y is never a vowel. For example, given the text string "computer science", this method would return "cempetir sceunco". Furthermore, to make this problem more interesting and the result look more palatable, this method must maintain the capitalization of vowels based on the vowel character that was originally in the position that each new vowel character is moved into. For example, "Ilkka Markus" should become "Ulkka Markis" instead of "ulkka MarkIs". Use the handy utility methods in the Character wrapper class to determine whether some particular character is in upper- or lowercase, and convert a character to upper- or lowercase as needed.arrow_forwardA pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items. The discount is equal to 20 percent of the cost of the other items, but not the pets. Implement a method: public static void discount(double[] prices, boolean[] isPet, int nItems) The method receives information about a particular sale. For the ith item, prices[i] is the price before any discount, and isPet[i] is true if the item is a pet. Write a program that prompts a cashier to enter each price and then a Y for a pet or N for another item. Use a price of –1 as a sentinel. Save the inputs in an array. Call the method that you implemented, and display the discount.arrow_forward

Example: Enter an input string: aabcded Output: The input string aabcded has two consecutive same letters Enter an input string: ababab Output: The input string ababab has no two consecutive same letters Enter an input string: abbbabab Output: The input string abbbabab has no two consecutive same letters [Note: In the case above we will not consider bbb as there are three consecutive b’s, we only need to find instances where there are only two consecutive letters]arrow_forwardA pet shop wants to give a discount to its clients if they buy one or more pets and at least four other items.
