Question 101
Assuming that the serializeBanana2() and the deserializeBanana2()
methods will correctly use Java serialization and given:
13. import java.io.*;
14. class Food {Food() { System.out.print(”1”); } }
15. class Fruit extends Food implements Serializable {
16. Fruit() { System.out.print(”2”); } }
17. public class Banana2 extends Fruit { int size = 42;
18. public static void main(String [] args) {
19. Banana2 b = new Banana2();
20. b.serializeBanana2(b); // assume correct serialization
21. b = b.deserializeBanana2(b); // assume correct
22. System.out.println(” restored “+ b.size + “ “); }
23. // more Banana2 methods
24. }
What is the result?

Question 102
Given:
10. public class Foo implements java.io.Serializable {
11. private int x;
12. public int getX() { return x; }
12.publicFoo(int x){this.x=x; }
13. private void writeObject( ObjectOutputStream s)
14. throws IOException {
15. // insert code here
16. }
17. }
Which code fragment, inserted at line 15, will allow Foo objects to be
correctly serialized and deserialized?
Question 103
Given:
12. NumberFormat nf= NumberFormat.getInstance();
13. nf.setMaximumFractionDigits(4);
14. nf.setMinimumFractionDigits(2);
15. String a = nf.format(3.1415926);
16. String b = nf.format(2);
Which two are true about the result if the default locale is Locale.US?
(Choose two.)
Question 104
Given:
11. double input = 314159.26;

12. NumberFormat nf= NumberFormat.getInstance(Locale.ITALIAN);
13. String b;
14. //insert code here
Which code, inserted at line 14, sets the value of b to 3 14.159,26?
A. b = nf.parse( input);
B. b = nf.format( input);
C. b = nf.equals( input);
D. b = nf.parseObject( input);
Question 105
Given:
14. DateFormat df;
15. Date date = new Date();
16. //insert code here
17. String s = df.format( date);
Which two, inserted independently at line 16, allow the code to
compile? (Choose two.)
Question 106
Given:
12. Date date = new Date();
13. df.setLocale(Locale.ITALY);
14. String s = df.format(date);
The variable df is an object of type DateFormat that has been
initialized in line 11. What is the result if this code is run on December
14, 2000?
