quoted someone who said :

if ( (intValue % 2) == 0 )
this.isEven = true;
else
this.isEven = false;

I would collapse this to:

this.isEven = ( intValue %2 ) == 0;

Most likely isEven could be made local. Then you could shorten
it further to:

isEven = ( intValue & 1 ) == 0;

I just threw that in for a lark to see if I could get it working.
Your program looks like its a bit complex to be a "simple beginner
project". Mine works and when I tested the times, I threw a huge int
at it and it still only took one second to return an answer for me.
My first attempt was one class, with a main and a method, but I
realized that it wasn't very object-oriented, which is why I switched
to the class/tester program you see before you.

What does this mean? "Most likely isEven could be made local"
.
