Learning Objectives:  The objective of this lab is to gain experience with writing recursive functions. Assignment: Write in Java programming language for the following recursive functions (no credit for iterative implementations) and Write a main method to test the functionsa. Write a recursive function writeLine() that writes a character repeatedly to form a line of n characters. For example, writeLine( * ,5) should produce the line *****. b. Write a recursive function writeBlock() that uses the method writeLine() to write m lines of n characters each. For example, writeBlock( * ,5,3) should produce the following output: *************** c. Write a recursive function writeBackward() that write a given string of characters in reverse order.  For example, writeBackward(“abcde”, 5) should give the output: edcba d. Write a recursive function displayArrayList(ArrayList int A, int first, int last) that receives an ArrayList A, first index, last index and displays the ArrayList in order e. Write a recursive function int vowels(String s, int size) that receives a string and returns the number of vowels in the string f. Write a recursive function void ReverseString (String s)  that receives a string and print the string backwards.   Submission Follow our class coding standard to complete this lab, compile and run it, check out for credit.
