In Java

Write an application called EvenOrOddCounter that prompts the user for integer numbers and counts how many of the numbers entered were even and how many were odd until a 0 is entered. There is additional information about while loops with sentinels at the end of this document.

Your program should:

use a while loop

prompt the user to enter a integer values until a 0 is entered

your codes prompt must resemble the examples below

determine if the value is even or odd. Hint: when even numbers are divided by 2 the remainder is 0

count the number of even values entered and the number of odd values entered

display results as shown in the example below

if the user enters a 0 for the first number, indicate that no values were entered

Listed below are two example outputs. Of course, your output can be different depending on the values entered.

Example 1:

Even or Odd Counter

----------------------

Please enter a series of integer values. 0 to quit.

Enter value 1: 34

Enter value 2: -2

Enter value 3: 3

Enter value 4: 0

The Results

-----------

Total values entered: 3

Even values entered : 2

Odd values entered : 1

Example 2:

Even or Odd Counter

----------------------

Please enter a series of integer values. 0 to quit.

Enter value 1: 0

The Results

-----------

No Values were entered.

More information about while loops and sentinels

Sometimes we dont know in advance how many values will be entered by the user. In a situation such as this, we ask the user to enter a sentinel value to indicate that no more values will be entered. When a user enters the sentinel, the loop terminates.

This assignment is an example of using a sentinel to signal that there are no more values to be entered. In this assignment 0 is the sentinel value.

The following is an outline of the general structure of using a while loop with a sentinel.

initialize variables

read the first value from the user //priming read

while (value != sentinel)

{

determine if the value is even or odd

increment the appropriate counter

do any other work

read the next value from the user //update read

}

report out results
