Java Foundation_9

_____automatically converts a primitive to the corresponding wrapper classes when needed if the generic type is specified in the declaration.

The syntax for introducing a generic is to declare a _____parameter in angle brackets

Method/field in a class (that is not a superclass) in a different package can access ___

Member in a superclass in a different package can access ___

For overriding, the overridden method should follow that:

An abstract class may contain any number of methods including ____

To which lines in the following code could you independently add static and/or final without introducing a compiler error?
1: abstract class Cat {

2: String name = "The Cat";

3: void clean() { }

4: }

5: class Lion extends Cat {

6: void clean() { }

7: }

How many different ways can you think of to write imports that will make this code compile?

public class ListHelper {

public List copyAndSortList(List original) {

List list = new ArrayList (original);

sort(list);

return list;

} }

In a instanceof B, the expression returns true _____,

You have three classes with which to work:

class HeavyAnimal { }

class Hippo extends HeavyAnimal { }

class Elephant extends HeavyAnimal { }

You see that Hippo is a subclass of HeavyAnimal but not Elephant. Remember that the exam starts with line numbers other than 1 when showing a code snippet. This is to tell you that you can assume the correct code comes before what you see. You can assume any missing code is correct and all imports are present.

12: HeavyAnimal hippo = new Hippo();

13: boolean b1 = hippo instanceof Hippo;

14: boolean b2 = hippo instanceof HeavyAnimal;

15: boolean b3 = hippo instanceof Elephant;
