• Question 41:

  Given:

  public class TestOperator {

  public static void main(String[] args) {

  int result = 30 -12 / (2*5)+1;

  System.out.print("Result = " + result);

  }

  }

  What is the result?

  A. Result = 2
  B. Result = 3
  C. Result = 28
  D. Result = 29
  E. Result = 30
  E. Result = 30

• Question 42:

  Given the following code fragment:

  

  What is the result if the integer value is 33?

  A. The fox jump lazy ...
  B. The fox lazy ...
  C. Quick fox over lazy ...
  D. Quick fox the ....
  B. The fox lazy ...

  ---

  33 is greater than 0.

  33 is not equal to 0.

  the is printed.

  33 is greater than 30

  fox is printed

  33 is greater then 10 (the two else if are skipped) lazy is printed

  finally ... is printed.

• Question 43:

  D. Option D
  B. Option B

• Question 44:

  Given the code fragment

  int var1 = -5;

  int var2 = var1--;

  int var3 = 0;

  if (var2 < 0) {

  var3 = var2++;

  } else {

  var3 = --var2;

  }

  System.out.println(var3);

  What is the result?

  A. 6
  B. 4
  C. 5
  D. 5
  E. 4
  F. Compilation fails
  C. 5

• Question 45:

  A. Compilation fails.
  B. The third argument is given the value null.
  C. The third argument is given the value void.
  D. The third argument is given the value zero.
  E. The third argument is given the appropriate false value for its declared type.
  F. An exception occurs when the method attempts to access the third argument.
  A. Compilation fails.

  The problem is noticed at build/compile time. At build you would receive an error message like: required: int,int,int found: int,int

• Question 46:

  Given:

  C. Compilation fails due to an error at line n2

• Question 47:

  Given: What is the result?

  

  A. Initialized Started
  B. Initialized Started Initialized

• Question 50:

  Given the code fragment:

  

  What is the result?

  A. Found Red
  B. Found Red Found Blue
  C. Found Red Found Blue Found White
  D. Found Red Found Blue Found White Found Default
  B. Found Red Found Blue

  ---

  As there is no break statement after the case "Red" statement the case Blue statement will run as well.

  Note: The body of a switch statement is known as a switch block. A statement in the switch block can be labeled with one or more case or default labels. The switch statement evaluates its expression, then executes all statements that follow the matching case label.

  Each break statement terminates the enclosing switch statement. Control flow continues with the first statement following the switch block. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.
