In Java

#1 - Recursive Power Method

Write a method that uses recursion to raise a number to a power. The method should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a non-negative integer. Demonstrate the method in a program.

#2 - Sum of Numbers

Write a method that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the method will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum. Demonstrate the method in a program.

#3 - String Reverser

Write a method that accepts a string argument and returns the string in reverse using recursion. For example - if the user enters the string "Java is fun!" it should return "!nuf si avaJ"

Make sure to create a separate java file for each exercise.
