the following statement is true...but how?
can anyone explain please 
all methods declared in a final class are implicitly final and hence cannot be
overridden.

In order to override you would have to be writing a subclass - impossible with a class declared final.

The final keyword ALWAYS makes things immutable once they have been declared and initialized. At least that is what I have read so far. Are there any exceptions?

There is a little trap for those programmers expecting that final static fields are unique in a class. If the same class is loaded several times by diferent class loaders in diferent name spaces, there would be several copies of those fields.
A bit off topic though. Just mentioned for you to consider in the future
