Question

Given 12. import java.util. 13. public class Explorer2 f 14. public static void main(StringlI args) { 15. TreeSet s new TreeSet Integer 0; 16. TreeSet subs new TreeSet Integer>() 17. for(int i 606 i 613, i++) 18. if(i%20) s.add(i); 19. subs - (TreeSet)s.subSet(608, true, 611, true), 20. s.add(629) 21. System.out println(s +"" + subs) 22. 23. What is the result? A. Compilation fails. B. An exception is thrown at runtime. C. [608, 610, 612, 629] [608, 610] D. (608, 610, 612, 629] [608, 610, 629] E. [606, 608, 610, 612, 629] [608, 610] F. [606, 608, 610, 612, 629] [608, 610, 629]

Explanation / Answer

Answer: E. [606, 608, 610, 612, 629] [608, 610]

Explanation:

s and subs share the same heap memory. Hence adding the value to s will add it subs as well. But subs is the subset of s within range 629 is not added. So the output would be

[606, 608, 610, 612, 629] [608, 610].
