Slice a string in groovy

I have a 18 character string I want characters 2-8 from. In python I can do this:

sliceMe = "nnYYYYYYnnnnnnnnnn"
print sliceMe[2:8]

prints

YYYYYY

I am looking for a way to do this same thing in groovy, and every explanation is REALLY long. Whats the elegant accepted way to do this in groovy (or java for that matter)?

groovy:000> sliceMe = "nnYYYYYYnnnnnnnnnn"
===> nnYYYYYYnnnnnnnnnn
groovy:000> sliceMe[2..7]
===> YYYYYY

Note the difference in the length being 1 less.

BZ.

You inherit all the Java methods off String so sliceMe.substring(2,7) should do the trick.

For future reference, you can compare the "Programming Language Examples Alike Cookbook" strings methods if you are unclear on how something is written in Python versus Groovy (or other syntaxes).

Here are the slicing python strings http://pleac.sourceforge.net/pleac_python/strings.html

And here are the slicing groovy strings: http://pleac.sourceforge.net/pleac_groovy/strings.html

Check the table of contents if you need to see other comparisons, its a good reference.
