This is a NO-GO!  You make it look like this was end of
isEven, but it is already end of class ChkNum.  please
align all close braces with the column at which the line
with the matching open brace starts!

Maybe you even confused yourself into thinking that ParmDemo
was "inside" ChkNum.

If the source file containing your code is called ParmDemo.java,
then you can make this class public, and then it might show up as
a possible starting class.

If the file is ChkNum.java or something completely different,
(which for non-public classes is possible), then rename it to
ParmDemo.java, first, and still make the class ParmDemo public.
