Q11. Given:
class Cake {
int model;
String flavor;
Cake() {
model = 0;
flavor = "Unknown";
}
}
public class Test {
public static void main(String[] args) {
Cake c = new Cake();
bake1(c);
System.out.println(c.model + " " + c.flavor);
bake2(c);
System.out.println(c.model + " " + c.flavor);
}
public static Cake bake1(Cake c) {
c.flavor = "Strawberry";
c.model = 1200;
return c;
}
public static void bake2(Cake c) {
c.flavor = "Chocolate";
c.model = 1230;
return;
}
}
What is the result?
A. 0 unknown 0 unknown
B. 1200 Strawberry 1200 Strawberry
C. 1200 Strawberry 1230 Chocolate
D. Compilation fails
Answer: C
Explanation: 1200 Strawberry 1230 Chocolate
Q12. Given the code fragment:
public class Test {
public static void main(String[] args) {
boolean isChecked = false;
int arry[] = {1,3,5,7,8,9};
int index = arry.length;
while ( <code1> ) {
if (arry[index-1] % 2 ==0) {
isChecked = true;
}
<code2>
}
System.out.print(arry(index]+", "+isChecked));
}
}
Which set of changes enable the code to print 1, true?
A. Replacing <code1> with index > 0 and replacing <code2> with index--;
B. Replacing <code1> with index > 0 and replacing <code2> with --index;
C. Replacing <code1> with index > 5 and replacing <code2> with --index ;
D. Replacing <code1> with index and replacing <code2> with --index ;
Answer: A
Explanation:
Note: Code in B (code2 is --index;). also works fine.

ay = az / aw;
} catch (ArithmeticException e1) {
System.out.println("Invalid Divisor");
} catch (Exception e2) {
aw = 1;
System.out.println("Divisor Changed");
}
ay = az /aw; // Line 14
System.out.println("Succesful Division " + ay);
}
}
What is the result?

Q17. Given:
class Sports {
int num_players;
String name, ground_condition;
Sports(int np, String sname, String sground){
num_players = np;
name = sname;
ground_condition = sground;
}
}
class Cricket extends Sports {
int num_umpires;
int num_substitutes;
Which code fragment can be inserted at line //insert code here to enable the code to compile?
A. Cricket() {
super(11, "Cricket", "Condidtion OK");
num_umpires =3;
num_substitutes=2;
}
B. Cricket() {
super.ground_condition = "Condition OK";
