Here's the belated Java solution.
import java.util.List;
import java.util.ArrayList;
import java.lang.Math;
class math {
public static List range(double n) {
return range(1,n,1);
}
public static List range(double n, double m) {
return range(n,m,1);
}
public static List range(double iMin, double iMax, double iStep) {
List ll = new ArrayList();
if (iMin <= iMax && iStep > 0) {
for (int i=0; i <= Math.floor((iMax-iMin)/iStep); i++) {
ll.add(new Double(iMin+i*iStep));
}
return ll;
}
if (iMin >= iMax && iStep < 0) {
for (int i=0; i <= Math.floor((iMin-iMax)/-iStep); i++) {
ll.add(new Double(iMin+i*iStep));
}
return ll;
}
// need to raise exception here
return ll;
}
}
class Range {
public static void main(String[] arg) {
System.out.println(math.range(5));
System.out.println(math.range(5,10));
System.out.println(math.range(5,7, 0.3));
System.out.println(math.range(5,-4, -2));
}
}

Dear functional programers,
i run services called a-python-a-day and a-java-a-day, where each day i
give a tip or snippet of code in these languages, also as a way for me
to learn these languages.
I've been running this perl-python a-day mailing list for several
months, and have accumulated a sizable tutorial here:
http://xahlee.org/perl-python/python.html
In the coming days, i'll be starting to translate a complete set of
tree processing functions. These functions, always takes a tree as
input (arbitrary nested list) and always returns a list of a definite
structure. Together, they form a particular functional programing
paradigm. See this page for the complete documentation as it exists
now:
http://xahlee.org/PerlMathemat ica_dir/Matica.html
As usuall, each day we will be spending about 20 minutes enjoying these
little exercises. If past experience is a good indication, then i
presume that in a month or two we will have built a complete set of
functions that manipulates tress, in languages Python and Java and
Perl. (the Perl set is already written)
I'm always interested in LISP and Haskell languages, but never
seriously learned them. I'm hoping that you functional programers in
these languages or learners, join me in these 15 minutes daily
exercises as a fun routine to learn languages or functional
programing.
I'm in particular very interested in the daily discussions of these
topics by functional programers, as well seeing such set of complete
code in scsh and Haskell. (Common Lisp or other functional languages
are always welcome of course)
