what is Final keyword concept?

[Muhammad Saifuddin]

Hi Ranchers,

My Questions is more about the concept of final keyword.

why we cannot extends final class in non-final class?
or what the usage of final keywords with Class, Methods and variables?
and what are conditions when we need to apply this key word with class, methods and variables?

Thanks

final variables is nothing but a constant whose values cannot be changed.

final method is the one which cannot be overridden (In terms of inheritance)

final class is the one which cannot be sublassed further
