    Consider following method

    Ensurepass 2017 PDF and VCE

    Which statement is true?

    1. This method is invalid.

    2. This method can be used only in an interface.

    3. This method can return anything.

    4. This method can be used only in an interface or an abstract class.

    5. 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#39;t return anything.

    Question No: 143

    Given:

    Ensurepass 2017 PDF and VCE

    What is the result?

    1. simaple A

    2. Capital A

    3. simaple A default Capital A

    4. simaple A default

    5. Compilation fails.

    Answer: C

    Explanation:

    Here we have to use two ternary operators combined. SO first we can use to check first condition which is x gt; 10, as follows;

    xgt;10?quot;gt;quot;: (when condition false) Now we have to use another to check if xlt;10 as follows; xlt;10?V:quot;=quot; We can combine these two by putting last ternary statement in the false position of first ternary statement as follows;

    xgt;10?quot;gt;quot;:xlt;10?#39;lt;#39;:quot;=quot;

    Question No: 144

    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?

    1. int i : array

    2. int i = 0; i lt; 1;

    3. ; ;

    D. ; i lt; 1; i

    E. i = 0; ilt;1;

    Answer: A,B,C

    Question No: 145

    Given the code fragment:

    class Student { int rollnumber; String name;

    List cources = new ArrayList();

    // insert code here public String toString() {

    return rollnumber quot; : quot; name quot; : quot; cources;

    }

    }

    And,

    public class Test {

    public static void main(String[] args) { List cs = newArrayList(); cs.add(quot;Javaquot;);

    cs.add(quot;Cquot;);

    Student s = new Student(123,quot;Fredquot;, cs); System.out.println(s);

    }

    }

    Which code fragment, when inserted at line // insert code here, enables class Test to print 123 : Fred : [Java, C]?

    1. private Student(int i, String name, List cs) {

      /* initialization code goes here */

      }

    2. public void Student(int i, String name, List cs) {

      /* initialization code goes here */

      }

    3. Student(int i, String name, List cs) {

      /* initialization code goes here */

      }

    4. Student(int i, String name, ArrayList cs) {

    /* initialization code goes here */

    }

    Answer: C Explanation: Incorrect:

    Not A: Student has private access line: Student s = new Student(123,quot;Fredquot;, cs);

    Not D: Cannot be applied to given types. Line: Student s = new Student(123,quot;Fredquot;, cs);

    Question No: 146

    Given:

    public class Test { static boolean bVar;

    public static void main(String[] args) { boolean bVar1 = true;

    int count =8; do {

    System.out.println(quot;Hello Java! quot; count); if (count gt;= 7) {

    bVar1 = false;

    }

    } while (bVar != bVar1 amp;amp; count gt; 4); count -= 2;

    }

    }

    What is the result?

    1. Hello Java! 8 Hello Java! 6 Hello Java! 4

    2. Hello Java! 8 Hello Java! 6

    3. Hello Java! 8

    4. Compilation fails
