Oracle 1z0-819 Question Answer

Given:

public class X {

}

and

public final class Y extends X {

}

What is the result of compiling these two classes?

The compilation fails because there is no zero args constructor defined in class X.

The compilation fails because either class X or class Y needs to implement the toString() method.

The compilation fails because a final class cannot extend another class.

The compilation succeeds.
