The following Java program application counts the number of odd and even numbers. The program also counts the number of zeros. I will be using the JCreator IDE in developing the program.
To start in this tutorial, first open the JCreator IDE, click new and paste the following code.
Sample run:
Please enter 20 integers, positive, negative, or zeros:
1 2 3 4 5 6 7 8 9 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 0
1 2 3 4 5 6 7 8 9 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 0
There are 10evens which also includes 2 zeros
Total number of odds is: 10
The program work as follows:
The statement
gets the next number and outputs the number.
The statement for
(
counter =
1
;
counter <=
N;
counter++
)
process and analyze the 20 numbers.
The statement
print the result and output the values of the variables zeros, evens and odds.
