Introduction to Groovy Course | DevelopIntelligence

Course Summary

The Introduction to Groovy course teaches is designed to demonstrate how to write basic scripts using the Groovy language.

The course begins by examining how Groovy seamlessly integrates with existing Java code and extends familiar classes like Strings, Lists, and Maps in a powerful yet natural way. Next, it covers File Input/Output (I/O) and Extensible Markup Language (XML) manipulation. The course concludes with a study of database integration and the networking capabilities of Groovy that dramatically reduce the amount of code that developers need to write.
