Q111. Given:
Which two classes use the shape class correctly?
A. Option A
B. Option B
C. Option C
D. Option D
E. Option E
F. Option F
Answer: B,E
Explanation: When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its parent class (E). However, if it does not, then the subclass must also be declared abstract (B). Note: An abstract class is a class that is declared abstract—it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed.

Q120. Consider following interface.
Which of the following will create instance of Runnable type?
A. Runnable run = 0 -> {System.out.println("Run");}
B. Runnable run = 0 -> System.outprintlnfRun");
C. Runnable run = 0 > System.outprintlnfRun");
D. Runnable run = > System.ouLprintlnfRun"};
E. None of the above.
Answer: A
Explanation:
Option A is the correct answer.
To create we have used following method with LocalDate class;
public static LocalDate of(intyear, int month, intdayOfMonth)
Here we need to remember that month is not zero based so if you pass 1 for month, then
month will be January.
Then we have used period object of 1 day and add to date object which makes current date
to next day, so final output is 2015-03-27. Hence option A is correct.
