CONVERTING A STRING TO A DATE IN GROOVY | BAELDUNG
To clarify, the Date.parse(String format, String input) method is available since version 1.5.7 of Groovy.. Version 2.4.1 introduced a variant accepting a third parameter indicating a timezone: Date.parse(String format, String input, TimeZone zone). From 2.5.0, however, there has been a breaking change and those enhancements are not shipped anymore with groovy-all.

GROOVY - DATA TYPE AND DECLARING VARIABLES - LOGICBIG
Groovy supports all Java types (primitive and reference types). All primitives types are auto converted to their wrapper types. So int a = 2 will become Integer a = 2. When declaring variables we can do one of the followings: Do not use any type (that will create a global variable): a = 2. Use keyword def (that will create a local variable):

THREE GROOVY STRING METHODS THAT WILL MAKE YOUR LIFE GROOVIER!
Until I’ve found those three useful String methods in the Groovy SDK: padLeft, padRight, and center. The first two are quite self-descriptive - they add padding on the left/right side, relative to the actual string length. So, for instance, when we call "abc" .padRight (10), seven spaces will be added after the last character in the string.
