Once upon a time switch was regarded as a convenient construct to reduce clutter of multiple if statements. And the best part is, this statement holds true even now. However, switch has been evolving and is undergoing a major feature rich change. Switch construct can now take types in its expressions to start with. Going further down, the case statements can have type checking combined with relevant expressions to have a control flow defined within the construct. And for what purpose? Answer: Ultimately to sew together the pattern matching story which Java is spinning these days.

The talk will discuss these features with real code examples and the attendees would get an overall idea of switch pattern concepts to start with. Additionally, with code-examples, attendees will be able to understand the dos and don'ts of using feature so as to use this construct effectively with a better of the internals of this. Fair amount of (Java) programming is the only pre-requisite for the attendees.
