Assignment #$1$ Recursion

Develop Java program for each of the following problems. Please name the programs as

indicated and add proper program headers and output labels as shown below.

Use only concepts and programming constructs$/$syntax we discussed in class.

Program name $(=$ Class name$)$ must be same as the java filename.

At first, design your strategy of this problem with recursive thinking, then write code.

Programming #$1(50$ points$)$

Write your Java program named PrintReverseYourName as follows. The main method prompts the

user to enter a string. The main method then passes the input string to method void

printCharsReverse$($String str$)$to recursively print given string in reverse. Again, method

void printCharsReverse$($String str$)$ is a recursive method which print $$one character$$ for each

invoke.

Format the outputs as follows. Test data shows values for illustration, user may enter values one per

line. Test strings does not show input prompts.

Test data:

Entered string: Hello world $//$Red characters are user input

Reversed string: dlrow olleH

Try again$($Y$/$N$)$: Y

Entered string: Data Structures and Algorithms

Reversed string: smhtiroglA dna serutcurtS ataD

Try again$($Y$/$N$)$: N

Document your code, use proper prompts for input, format outputs as shown above, use sound coding

practices we learned thus far, do not hard code inputs, allow program re$-$runs, and test your code

thoroughly.

Programming #$2(50$ points$)$

Write a java program $($name it AverageGradeYourName$)$ as follows: The main method prompts the

user to enter number of students in a class $($class size is integer value$),$ then prom
