SELECT ALLL POSSIBLE RESPONSES

Select one or more:

a. Because the variable a is private, no class other than First can access it.

b. Nothing is wrong with the code, it will compile.

c. The class Second cannot extend First, beacuse the class First is a terminal class.

d. final is not a valid keyword for a class, it is only used with constants.

e. You cannot call the println() method without passing a String to it.

Answer:

a. Because the variable a is private, no class other than First can access it.

c. The class Second cannot extend First, beacuse the class First is a terminal class.

These two are the correct answers.

Final class can not be inherited. So once we apply final key word on class that is a final class and can not be inherited.

\"a\" variable is a private variable and the scope of that variable is with in that same class and can not be visiblt to other classes.
