Question
Please help me with the below using java
3 CHANGE THIS TO A RECURSIVE METHOD Write a recursive version of this looping program. (Hint: You need to replace the While loop with a recursive method.) public class Reverse { public static void main(String [] args) { String str= JOptionPane.showInput Dialog("Type a string to reverse: "); int index str.length () - 1; while (index >= 0) ( print (str.substring (index, index + 1)); index--; 4 THE BUNNY EAR PROBLEM We have bunnies standing in a line, numbered 1, 2, ... The odd bunnies (1, 3, ..) have the normal 2 ears. The even bunnies (2, 4, ..) we'll say have 3 ears, because they each have a raised foot. Recursively return the number of "ears" in the bunny line 1, 2, ... n (without loops or multiplication) for the number of bunnies entered by the user. bunnyEars2(0)→→O bunnyEars2(1)→ 2 bunnyEars2(2)→→ 5
