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 explanatio开发者_JAVA技巧n 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.
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.
