1. Recursive Multiplication
Write a recursive function that accepts two arguments into the parameters x and y. The
function should return the value of x times y. Remember, multiplication can be performed
as repeated addition as follows:
7* 4 = 4 + 4 + 4 +4 + 4 + 4 + 4
Recursive Power MethodWrite a method called powCal that uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponent and the second argument is the number to be raised (example” powCal(10,2) means 210). Assume that the exponent is a nonnegative integer. Demonstrate the method in a program called Recursive
(This means that you need to write a program that has at least two methods: main and powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCal method work).
If your first name starts with a letter from A-J inclusively:
Write a recursive method that takes a string as argument and determines if the string has more vowels than consonants. Test the method by asking the user to enter a string. Hint: Write your recursive method to first count vowels and consonants.

Q Search kola shreya@columbus X275: Recursion Programming Exercise: Check Palindrome X275: Recursion Programming Exercise: Check Palindrome Write a recursive function named checkPalindrome that takes a string as input, and returns true if the string is a palindrome and false if it is not a palindrome. A string is a palindrome if it reads the same forwards or backwards. Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position a and continuing to (but not including) the character at position b.
