Course Groovy Programming

In the course Groovy Programming participants learn to program in the dynamic scripting language Groovy, which is also considered Java++. Groovy is a JVM language which means that Groovy scripts are interoperable with Java code and can therefore easily be used together with Java in the same application. Groovy is a natural extension to the Java syntax and offers, among other things, a simpler syntax for lists, ranges, maps and regular expressions.

    Groovy Intro

    The course starts with an introduction to the basic features of Groovy and covers dynamic typing and type inference in Groovy. It is discussed how Groovy differs from Java with much less boilerplate code and support for scripting.

    Language Syntax and Data Structures

    Next the Groovy language syntax with variables, data types, conditionals, operators and loops is covered. Groovy data structures like lists, maps and sets are also treated and also how Groovy uses the Java Collection Framework.

    Methods and Closures

    Groovy methods, parameters passing and closures are also part of the course program. Groovy closures are anonymous code blocks that, as function objects with the scope in which they are created, are stored to be executed at a later time, with or without additional parameters.

    Classes and Traits

    And just like Java, Groovy is an object-oriented language and attention is paid to how you use classes, constructors, fields, interfaces and traits in Groovy.

    XML and JSON

    File I/O is on the program of the course as well and in that context the commonly used data formats XML and JSON are treated and how Groovy deals with them.

    Meta Programming

    Finally the course concludes with a discussion of meta programming in Groovy, which makes it possible to call methods dynamically and to create classes and methods on the fly.
