Given the code fragment:

Assume that the system date is June 20, 2014. What is the result?

• A.Option B
• B.Option A
• C.Option C
• D.Option D

Given:
1. public class SampleClass {
2. public static void main (String[] args) {
3. AnotherSampleClass asc = new AnotherSampleClass();
4. SampleClass sc = new SampleClass();
5. // insert code here
6. }
7. }
8. class AnotherSampleClass extends SampleClass {
9. }
Which statement, when inserted into line 5, enables the code to compile?

• A.asc = sc;
• B.asc = (Object) sc;
• C.asc = sc.clone;
• D.sc = asc;

Given the code fragment?
public class Test {
public static void main(String[] args) {
Test t = new Test();
int[] arr = new int[10];
arr = t.subArray(arr,0,2);
}
// insert code here
}
Which method can be inserted at line // insert code here to enable the code to compile?

• A.public int[] subArray(int src, int start, int end) { return src;
  }
• B.public int[] subArray(int[] src, int start, int end) { return src;
  }
• C.public int subArray(int src, int start, int end) { return src;
  }
• D.public int subArray(int[] src, int start, int end) { return src;
  }

Given the code fragment:

What is the result?

• A.A B C
• B.A B D E
• C.Compilation fails.
• D.A B C D E

Given:
package pkg1;
class Bb { }
public class Ee {
private Ee() { }
}
package pkg2;
final class Ww;
package pkg3;
public abstract class Dd { void m() { } }
And,
1. package pkg4;
2. import pkg1.*;
3. import pkg2.*;
4. import pkg3.*;
5. // insert a class definition here
Which two class definitions, when inserted independently at line 5, enable the code to compile?

• A.class Cc extends Ee { }
• B.class Cc extends Ww { }
• C.class Cc extends Dd { }
• D.class Cc extends Bb { }
