java程序代写 Write in Java programming language for the following recursive functions (no credit for iterative implementations) and Write a main method to test the functions

Lab 10:  Practicing Recursive Functions

 

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 functions

a. 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.
