Local variable type inference was introduced as a new Java language feature in Java SE 10. Gone are the days of explicitly having to define the type of a variable; let the compiler do it for you with the magic of var.
At first sight, this looks like a small change that will eliminate unnecessary boiler-plate code and reduce how much typing (on the keyboard) is required to maintain strong typing (of the language). However, as with many features, there are some unexpected nuances as well as both good and bad use cases.
In this BoF, Stuart and Simon will take a series of examples of the use of var and discuss their technical merits. We’ll involve the audience to provide different perspectives on why developers would or would not use var in these ways.
Time will be made available for attendees to provide examples they may have encountered, enabling discussion of their merits.
