Assignment 9: CSE 205: Object-Oriented Program & Data

 Assignment 9: CSE 205: Object-Oriented Program & Data 

Important: This is an individual assignment. Please do not collaborate.
No late assignment will be accepted.
Make sure that you write every line of your code. Using code written by
someone else will be considered a violation of the academic integrity and
will result in a report to the Dean's office.
It must be submitted on-line (Course website).
Go to "GradeScope" tab on Canvas - CSE205 - Assignment9, and upload
your program file.
Minimal Submitted Files
You are required, but not limited, to turn in the following source file:
Assignment9.java file (you need to create this file)
Requirements to get full credits in Documentation
1. The assignment number, your name, StudentID, Lecture day/time, and a
class description need to be included at the top of each file/class.
2. A description of each method is also needed.
3. Some additional comments inside of methods (especially for a "main"
method) to explain code that are hard to follow should be written.
You are not allowed to use the Scanner class in this assignment
and any assignment after this one. You will need to
use InputStreamReader and BufferedReader (they are in java.io
package)to process input and also take care of IOException.
New Skills to be Applied
In addition to what has been covered in previous assignments, the use of
the following items, discussed in class, will probably be needed:

- Recursion
- One-dimensional arrays
Program Description
Assignment #9 will be the construction of a program that reads in a
sequence of integers from standard input until 0 is read, and store them in
an array (including 0). This is done using iteration (choose one of for, while,
or do while loop). You may assume that there will not be more than 100
numbers.
Then compute the minimum number, count odd integers, compute the sum
of numbers that are larger than the first number in the array, and compute
the largest even integer in the sequence using recursion. Thus, you will
create recursive methods findMin, countOddNumbers,
computeLargestEven, and sumOfNumbersLargerThanFirst in
Assignment9 class and they will be called by a main method.
Specifically, the following recursive methods must be implemented (These
methods should not contain any loop):
 public static int findMin(int[] numbers, int startIndex, int endIndex)
 public static int countOddNumbers(int[] elements, int startIndex, int
endIndex)
 public static int computeLargestEven(int[] elements, int startIndex, int
endIndex)
 public static int sumOfNumbersLargerThanFirst(int[] elements, int
startIndex, int endIndex, int firstNumber)
If these methods are implemented using a Loop or any Static Variable,
points will be deducted even if your program passes test cases. DO
NOT use any Static Variables.
The program should output the results of those calculations to standard
output. Your program will continue to read in numbers until the number 0 is
entered. At this point, the calculations will be outputted in the following
format:
The minimum number is 0
The count of odd integers in the sequence is 0
The largest even integer in the sequence is 0
The sum of numbers larger than the first is 0

Note that the result values will be different depending on test cases (not
always 0).
Do not output a prompt to query for the numbers. The number 0 is
included in the sequence of numbers and should be included in all of your
calculations.
Test Cases
Download the following input files, input1.txt, input2.txt, input3.txt, and
input4.txt, and the following output files, output1.txt, output2.txt, output3.txt,
and output4, and save them in the same directory as Assignment9.java is
located.

Error Handling
Your program should be robust enough to handle all test cases above.
--------------------------------------------
What to turn in:
-Submit your Assignment9.java file using Gradescope- Assignment9 on
