Answer: False

Explanation: In java, whenever a final class is declared it cannot be extended further and also it is not possible for a declared class to be overridden in the sub class. A class can be declared final by using the final keyword. Final class cannot be extended but they can be used to extend the other classes.Therefore the final class cannot be sub classed before it in java.
