Java Programming Cours... e Java Web Programm QUESTION 1 You cannot create an instance of an abstract class using the new operator. lse QUESTION 2 Analyze the following code: public dass Test public static void main(StingO args) Test test new Test 0, test set Action (0 system out print(Action 11)); public void setAction(T t) tm 10; interface T public void m10. public void m20. question 2 More than 1 correct answer he program displays Action 1 The program has a compile error because T is not a functional interface. T contains multiple methods. he program would work if you delete the method m2 from the interface T The program has a runtime error because T is not a functional interface. T contains multiple methods.

Solution

1. True
2. the program has c compile error because T is not a functional interface.
3. is always true
4. false
5. false
6. false, it can refer to different types of objects and polymorphism means shwoing different forms.
7. cant exist-you cannot instantiate an Abstract class
8. true
9. false
10. new String(\"abc) and new Date()
11. true
12. implementing interface because since a class can implement any number of interfaces, that class is in essence using the interface classes as if those interfaces were defined in this class. so this class is inherting the method and constants of the interfaces. Further the class could extend another class and thus inherit directly and indirectly from multiple classes. This is not the exact same as multipke inheritance.,but it is as close as java comes to that cncept.
13. \"the default constructor of A is invoked\" \"the default constructor of B is invoked\"
14. the method m is not overridden in b. B inherits the method m from A and defines an overloaded method m in b.
15. coverage- determines how much of program has been tested
black box testing- testing that does not take program structure into account
boundary test- testing that examines the limit of correct input
white box testing- testing that take program structure into account
16. true
17. super
18. false
19. 5 is the answer
20. composition means that a class contains data field that refrence another object
21. false
22.interface A{ void print();}
23. public void actionPerformed(ActionEvent e)

24. An object of B contains data fields j,k,m;
25. Comparable<MyInt> /MyInt
26. false, A final class cannot be subclassed.
27. false
28. public boolean equals(Object other)
29. The constructor of class A is called and it displays i from A is 7
30. The methods in an object are serialized.
31. EventHandler<ActionEvent>
32. s, o, and d reference the same String object because Casting object reference variable does not affect the contents of the object
33. yes, because the arraylist is of type string and we are adding an integer value to arraylist of string type.
34. that data fields should be declared private
