There's no such thing as a final object.

actually they can be changed, but the variable itself cannot be reassigned

So you can do

final Object[] objs = ...

objs[0] =

but you can't do

objs = ...

> Final class-- cant subclassed.

Is there such a thing?

the code is actually quite a junk.

whats happening is , in a class the decl is as

final Object obj= new Object;

then this obj is passed to another function in another class where it is not treated as final. Since i thought the that the final keyword is for object, i got little confused. But, when i took the final Key word is for the handle to the object, then every thing looks clear.

Any class is an object once instantiated, so 'final' in this context doesn't mean anything.

final Point pt = new Point(10,66);

This is an example of a final variable. But be careful to distinquish between the variable pt and the object it refers to: that Point object can be changed. The effect of final is to prevent (further) assignment to pt:

pt.x += 1; //legal

pt = new Point(11,66); //syntax error
