This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.

K&B Two Minute Drill Chapter 1 wrote:final variables have the following properties:
final variables cannot be reinitialized once assigned a value.
final reference variables cannot refer to a different object once the object has been assigned to the final variable.
final reference variables must be initialized before the constructor completes.
