Correct Answer:AB

Given:
1. abstract class Shape {
2. Shape ( ) { System.out.println (“Shape”); }
3. protected void area ( ) { System.out.println (“Shape”); } 4. }
5.
6. class Square extends Shape {
7. int side;
8. Square int side {
9. /* insert code here */
10. this.side = side;
11. }
12. public void area ( ) { System.out.println (“Square”); }
13. }
14. class Rectangle extends Square {
15. int len, br;
16. Rectangle (int x, int y) {
17. /* insert code here */
18. len = x, br = y;
19. }
20. void area ( ) { System.out.println (“Rectangle”); }
21. }

Correct Answer:CE

Given the code fragment:
Path p1 = Paths.get(“/Pics/MyPic.jpeg”); System.out.println (p1.getNameCount() + “:” + p1.getName(1) +
