Given: 10. class Line { 11. public static class Point { } 12. } 13. 14. class Triangle { 15. // insert code here 16. } Which code, inserted at line 15, creates an instance of the Point class defined in Line?

Given: 10. class Line { 11. public class Point { public int x,y; } 12. public Point getPoint() { return new Point(); } 13. } 14. class Triangle { 15. public Triangle() { 16. // insert code here 17. } 18. } Which code, inserted at line 16, correctly retrieves a local instance of a Point object?

Given: 10. class One { 11. public One() { System.out.print(1); } 12. } 13. class Two extends One { 14. public Two() { System.out.print(2); } 15. } 16. class Three extends Two { 17. public Three() { System.out.print(3); } 18. } 19. public class Numbers{ 20. public static void main( String[] argv) { new Three(); } 21. } What is the result when this code is executed?
