​def sampleText 
// Normal ternary operator.
def ternaryOutput = (sampleText != null) ? sampleText : 'Hello Groovy!'

// The Elvis operator in action. We must read: 'If sampleText is not null assign
// sampleText to elvisOuput, otherwise assign 'Viva Las Vegas!' to elvisOutput.
def elvisOutput = sampleText ?: 'Viva Las Vegas!'

Groovy Tuples

-
A tuple is an ordered, immutable list of elements.  Groovy has it's own  groovy.lang.Tuple  class.  We can create an instance of a  Tuple  by providing all elements that need to be in the  Tuple  via the constructor.  We cannot add new elements to a  Tuple  instance or remove elements.  We cannot even change elements in a tuple, so it is completely immutable.  This makes it very useable as return value for a method where we need to return multiple values.  Groovy also provides a  Tuple2  class that can be used for tuple instance of only two elements. The elements are typed in a  Tuple2  instance. def  tuple  =  new  Tuple ( 'one' ,  1 ,  new  Expando ( number :  1 ) )   assert  tuple . size ( )  ==  3   // To get the value of an element // at a certain position we use // the get(index) method. assert  tuple . get ( 0 )  ==...

Spring Cert Notes

-
Dependency Injection In Spring DI Basics • Reduces coupling between classes • Classes do not obtain their dependencies (collaborators), Spring container provides proper dependency based on configuration provided • Enables easy switching of dependencies based en current needs - local development vs production environment, easy mocking for unit tests, in memory database vs production one, etc. • Promotes programming to interfaces • Spring-managed objects are called "beans" • Beans are written as POJOs, no need to inherit Spring base classes or implement spring interfaces • Classes can be completely independent of Spring framework (although for convenience Spring annotations are often used) • Lifecycle of beans is managed centrally by Spring container (eg. enforces singleton state of bean/ one instance pers session. one instance per HTTP request/...) • Spring configuration (including DI) is possible either via XML or Java configuration files (newer, more popular approac...
