Q31. Given:
public class Test {
static boolean bVar;
public static void main(String[] args) {
boolean bVar1 = true;
int count =8;
do {
System.out.println("Hello Java! " +count);
if (count >= 7) {
bVar1 = false;
}
} while (bVar != bVar1 && count > 4);
count -= 2;
}
}
What is the result?
A. Hello Java! 8 Hello Java! 6 Hello Java! 4
B. Hello Java! 8 Hello Java! 6
C. Hello Java! 8
D. Compilation fails
Answer: C
Explanation: Hello Java! 8
Q32. Which of the following data types will allow the following code snippet to compile?
A. long
B. double
C. int
D. float
E. byte
Answer: B,D
Explanation:
Option B and D are the correct answer.
Since the variables I and j are floats, resultant will be float type too. So we have to use float
or primitive type which can hold float, such a primitive type is double, it has wider range
and also can hold floating point numbers, hence we can use double or float for the blank.
As explained above options B and D are correct.
long and int can't be used with floating point numbers so option A is incorrect.
Option E is incorrect as it have smaller range and also can't be used with floating point
numbers.

Q33. Given:
Which is true?
A. Sum for 0 to 0 = 55
B. Sum for 0 to 10 = 55
C. Compilation fails due to error on line 6.
D. Compilation fails due to error on line 7.
E. An Exception is thrown at the runtime.
Answer: D
Explanation:
Loop variables scope limited to that enclosing loop. So in this case, the scope of the loop variable x declared at line 5, limited to that for loop. Trying to access that variable at line 7, which is out of scope of the variable x, causes a compile time error. So compilation fails
due to error at line 7. Hence option D is correct.
Options A and B are incorrect, since code fails to compile.

Q34. Given:
What is the result?
A. box
B. nbo
C. bo
D. nb
E. An exception is thrown at runtime
Answer: E
Q35. Consider following method
Which statement is true?
A. This method is invalid.
B. This method can be used only in an interface.
C. This method can return anything.
D. This method can be used only in an interface or an abstract class.
E. None of above.
Answer: B
Explanation:
Given method is declared as default method so we can use it only inside an interface.
Hence option B is correct and option D is incorrect.
Option A is incorrect as it is valid method. Option C is incorrect as return type is void, which
means we can't return anything.
Q36. Given:
What is the result?
A. The program prints nothing
B. d
C. A StringIndexOutOfBoundsException is thrown at runtime.
D. AnArrayIndexOutOfBoundsException is thrown at runtime.
E. A NullPointerException is thrown at runtime.
Answer: C
Q37. Given the code fragment:
What is the result?

Answer: C
Q38. Given:
How many MarkList instances are created in memory at runtime?
A. 1
B. 2
C. 3
D. 4
Answer: A
Q39. Given:
public class FieldInit {
char c;
boolean b;
float f;
void printAll() {
System.out.println("c = " + c);
System.out.println("c = " + b);
System.out.println("c = " + f);
}
public static void main(String[] args) {
FieldInit f = new FieldInit();
f.printAll();
}
}
What is the result?
A. c = null
b = false
f = 0.0F
B. c = 0
b = false
f = 0.0f
C. c = null
b = true
f = 0.0
D. c =
b = false
f = 0.0
Answer: D
