In the above code the constructor is setting a value to the final variable name.
How is that possible? This runs fine and prints FINAL VARIABLE!
Please explain.

A final field or variable can be set up once and once only. That can be done at declaration, in an initialiser (fields only) or in the constructor (again fields only).
 
It is sorta covered in the JavaRanch Style Guide.
