THREE GROOVY STRING METHODS THAT WILL MAKE YOUR LIFE GROOVIER!
From e.printstacktrace.blog
- padLeft, padRight, and center. How many times you tried to format some console text using printf, and you have to google " printf pad to right", etc.?
- and * operators. Using + operator to concatenate two strings is nothing special. Groovy, however, adds support for - (subtraction) and * (multiplication) operators as well.
- String translation with the tr method. Groovy’s text translation method seems to be unknown to many programmers. Some of you might think that it is just an equivalent of good old String.replaceAll() method.
CONVERTING A STRING TO INT IN GROOVY - STACK OVERFLOW
just wanted to add, that since Groovy 1.8 int is indeed int.Groovy will still display the Integer class, because of boxing, but you will for example not be able to assign null to an int, which was possible in 1.0.We considered the change being non-critical, since you already could not use null as argument for a method call parameter of type int.This is all still different from …

GROOVY: NO NEED TO USE SUBSTRING() - GROOOVYGEORGE ON GRAILS
Groovy’s range operators are just great. If you’ve came across the problem to cut a string’s last 2 characters, in Java, you’d probably write something like this: int s = theString.length() String cutChars = theString.substring(0, s) In Groovy you don’t need that stuff. Just use . String cutChars = theString[0..-3] and you’re done :-).
