Users access applications on PCs and mobile devices today. There are two obvious ways to build front-ends for these devices: Web applications and native applications. Cross-platform UI frameworks combine advantages from both approaches. Karsten will look at all these toolkits from the perspective of a Java developer and suggest which one to use in three common scenarios.

Applications that run on the JVM benefit from a managed runtime environment with JIT compilation that can easily exceed the performance of natively compiled code. In this byte-sized session, Simon Ritter will look at some ways to improve the performance of your JVM-based applications without having to change a single line of code or even recompile!
Why should you need to download java, set up a build system and configure your IDE to just play and do some scripting and automation tasks?
