Jazoon: Thursday Keynote

Thursday’s keynote was “Effective Java Reloaded” by Joshua Bloch where he presented a few key points from his new book.

The examples showed how to replace bit fields (or rather int constants which are used a bit fields) with EnumSet and EnumMap, and how to do lazy initialization for various cases effectively and correctly. If you’re a Java programmer who does more than “Hello World”, this book is a must have because it explains not only how to do things but how to do things elegantly and why.
