  int a = 0, z=10;

  while (a < z) {

  a++;

  --z;

  }

  System.out.print(a + " : " + z);

• Question 275:

  Given the code fragment:

  public class ForTest {

  public static void main(String[] args) {

  int[] array = {1, 2, 3};

  for ( foo ) {

  }

  }

  Which three code fragments, when replaced individually for foo, enables the program to compile?

  A. int i : array

  B. int i = 0; i < 1;

  C. ; ;

  D. ; i < 1; i++

  E. i = 0; i<1;

• Question 276:

  Given:

  public class Marklist {

  int num;

  public static void graceMarks(Marklist obj4) {

  obj4.num += 10;

  }

  public static void main(String[] args) {

  MarkList obj1 = new MarkList();

  MarkList obj2 = obj1;

  MarkList obj1 = null;

  obj2.num = 60;

  graceMarks(obj2);

  }

  }

  How many objects are created in the memory runtime?

  A. 1

  B. 2

  C. 3

  D. 4

  Correct Answer: B

  Explanation: obj1 and obj3.

  when you do e2 = e1 you're copying object references - you're not making a copy of the object - and so the variables e1 and e2 will both point to the same object.

• Question 277:

  C. A runtime error is thrown in the thread "main".

  D. Execution completes normally, and Ready to us?is printed to the console.

  E. The code fails to compile because a throws keyword is required.

  Correct Answer: C

• Question 279:

  Given:

  public class Test {

  static boolean bVar;

  public static void main(String[] args) {

  boolean bVar1 = true;
