c)

d) None

itemMap.remove("orange"); itemMap.put("orange", new Item("Orange") );

((Item)itemMap.get(“orange”)).name = “Orange”;

itemMap.put("orange", new Item("Orange") );

None of above

code attribute cannot be changed as Item class doesn’t have setter method for it.

for (int i = 0; i < itemList.size(); i++) { if(itemList.get(i) != null) { ((Item)itemList.get(i)).code = 50+i; } }

int i = 0; Item im = null; while (i < itemList.size()) { im = (Item)itemList.get(i); if(im != null) { im.code = 50+i; } i++; }

int i = 0; Item im = null; Iterator itr = itemList.iterator(); while (itr.hasNext()) { im =(Item) itr.next(); im.code = 50+i; i++; }

Item im = new Item(null); im = (Item ) itemList.get(0);

Item im = new Item(“Done”); im = (Item ) itemList.get(0);

Item im = null; im = (Item ) itemList.get(0);

All of the above.

Function call:- changeName(im); Function implementation :- { im.name = "Done"; return null; }

Function call:- changeName(im); Function implementation :- { im = new Item("Done"); return null; }

Function call :- im = changeName(im); function implementation :- { Item otherObject = new Item("Done"); return otherObject; }

All of the above

Function call:- changeName(im); Function implementation :- { im.name = "Done"; return null; }

Function call:- changeName(im); Function implementation :- { im = new Item("Done"); return null; }

Function call :- im = changeName(im); function implementation :- { Item otherObject = new Item("Done"); return otherObject; }

All of the above

im.name = "Done";

Item otherObject = new Item(“Done”); itemList.set(49, otherObject);

((Item)itemList.get(49)).name = “Done”;

None of above is correct as they are not changing 50th element.

Item im = new Item(null); im = (Item ) itemList.get(0);

Item im = new Item(“Done”); im = (Item ) itemList.get(0);

Item im = null; im = (Item ) itemList.get(0);

All of the above.

itemMap.remove("orange"); itemMap.put("orange", new Item("Orange") );

((Item)itemMap.get(“orange”)).name = “Orange”;

itemMap.put("orange", new Item("Orange") );
