84. try {
85. ResourceConnection con =
resourceFactory.getConnection();
86. Results r = con.query(”GET INFO FROM CUSTOMER”);
87. info = r.getData();
88. con.close();
89. } catch (ResourceException re) {
90. errorLog.write(re.getMessage());
91. }
92. return info;
Which is true if a ResourceException is thrown on line 86?
1 Line 92 will not execute.
2 The connection will not be retrieved in line
85.
3 The resource connection will not be closed
on line 88.
4 The enclosing method will throw an exception
to its caller.
11. static class A {
12. void process() throws Exception { throw new Exception();
}
13. }
14. static class B extends A {
15. void process() { System.out.println(”B”); }
16. }
17. public static void main(String[] args) {
18. new B().process();
19. }
What is the result?
1 B
2 The code runs with no output.
3 Compilation fails because of an error in
line 12.
4 Compilation fails because of an error in
line 15.
Given:
10. interface A { void x(); }
11. class B implements A { public void x() { } public
voidy() { } }
12. class C extends B { public void x() {} }
And:
20. java.util.List list = new java.util.ArrayList();
21. list.add(new B());
22. list.add(new C());
23. for (A a:list) {
24. a.x();
25. a.y();;
26. }
What is the result?
1 Compilation fails because of an error in
line 25.
2 The code runs with no output.
3 An exception is thrown at runtime.
4 Compilation fails because of an error in
line 20.

compile?
a)Direction d = NORTH;
b)Nav.Direction d = NORTH;
c)Direction d = Direction.NORTH;
d)Nav.Direction d = Nav.Direction.NORTH;

Write a java program to find the route that connects
between Red and Green Cells.
General Rules for traversal
1. You can traverse from one cell to another
vertically, horizontally or diagonally.
2. You cannot traverse through Black cells.
3. There should be only one Red and Green cell and at
least one of each should be present. Otherwise the array is
invalid.
4. You cannot revisit a cell that you have already
traversed.
5. The maze need not be in the same as given in the
above example
