As I explained in the introduction, this book assumes an intermediate-level knowledge of Java. This is because I have noticed that most people learning Groovy have some Java background, and—impatient with the shortcomings and limitations of Java—have decided to give Groovy a try. They couldn’t be more right! This chapter focuses mainly on explaining the similarities and differences between Java and Groovy and how to integrate Groovy with Java. Thanks to the similarity between Groovy’s syntax and Java’s, the transition from Java to Groovy is a smooth one with an almost flat learning curve.
In Groovy, however, methods and fields are all lq^he_ by default, making them accessible from anywhere. Checked Exceptions In Groovy you don’t need to worry about catching or declaring checked exceptions because they will be wrapped up as NqjPeiaAt_alpekjs. The code in Listing 2-3 creates a new file in Java by using a call to the _na]paJasBeha method in the Beha class. Because this method throws an EKAt_alpekj (a checked exception), you have to wrap the code in a pnu+_]p_d block. Listing 2-3 also shows the same example written in Groovy, but this time you don’t have to wrap _na]paJasBeha with a pnu+_]p_d block because Groovy will automatically wrap up the exception with a NqjPeiaAt_alpekj.
