Question

Write a java file called RecursiveMethods and provide the following methods (these
methods are required to be fully recursive in that they contain no loops at all):

1) Write a recursive method that takes as input a String S and returns the number
of uppercase letters in S.

2) Write a recursive method that finds the number of occurrences of a specified
letter in a string using the following method header:
public static int count(String str, char a)

3) Write a method that checks if the first n elements of an array a of integers are
already in ascending order:
public static Boolean isSorted(int [] a, int n)
This method does not modify the contents of the array a in any way, but
simply checks if the elements are sorted or not.

4) Write a method that takes as input a string s and returns the same string where
the vowels have been removed.
public static String NoVowel(String str)
For simplicity, assume that you already have a method Boolean isVowel(char c)
that tells whether the character c is a vowel.

Provide a main method to test all the above methods.

note: do not use any loops, it must be recursive
