• Question 342:

  Which of the following can fill in the blank in this code to make it compile? (Select 2 options.)

  

  A. On line 1, fill in throws

  B. On line 1, fill in throws new

  C. On line 2, fill in throw new

  D. On line 2, fill in throws

  E. On line 2, fill in throws new

  Correct Answer: AC

  Option A and C are the correct answer.

  In a method declaration, the keyword throws is used. So here at line 1 we have to use option A.

  To actually throw an exception, the keyword throw is used and a new exception is created, so at line 2 we

  have to use throw and new keywords, which is option C. Finally it will look like;

  public void method() throws Exception {

  throw new Exception0;

  }

  REFERENCE : httpsy/docs.oracle.com/javase/tutorial/essential/io/fileOps.html#exception The correct

  answer is: On line 1, fill in throws. On line 2, fill in throw new

• Question 343:

• Question 345:

  Given:

  public class Test1 {

  static void doubling (Integer ref, int pv) {

  ref =20;

  pv = 20;

  }

  public static void main(String[] args) {

  Integer iObj = new Integer(10);

  int iVar = 10;

  doubling(iObj++, iVar++);

  System.out.println(iObj+ ", "+iVar);

  What is the result?

  A. 11, 11

  B. 10, 10

  C. 21, 11

  D. 20, 20

  E. 11, 12

  Correct Answer: A

  Explanation: The code doubling(iObj++, iVar++); increases both variables from to 10 to 11.

• Question 346:

  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?

  

  Correct Answer: D

• Question 350:

  Consider following interface.

  

  Which of the following will create instance of Runnable type?

  A. Runnable run = 0 -> {System.out.println("Run");}

  B. Runnable run = 0 -> System.outprintlnfRun");

  C. Runnable run = 0 > System.outprintlnfRun");

  D. Runnable run = > System.ouLprintlnfRun"};

  E. None of the above.

  Correct Answer: A

  Option A is the correct answer.

  To create we have used following method with LocalDate class; public static LocalDate of(intyear, int

  month, intdayOfMonth) Here we need to remember that month is not zero based so if you pass 1 for

  month, then month will be January.

  Then we have used period object of 1 day and add to date object which makes current date to next day, so

  final output is 2015-03-27. Hence option A is correct.
