Errata in OCA/OCP 7 Kathy Sierra Bert Bates

[sourabh chhabra]

Hello Everyone

Though I did go thru the errata page (https://coderanch.com/t/641206/certification/Errata-OCA-OCP-Java-SE) for the OCA/OCP 7 study guide by Kathy Sierra but I did not find this in there.

I would like to check with everyone regarding 1 of the Self Test question in chapter 11, Generics and Collections.

This is question 1 of self test of chapter 11.
For me the correct answer is Option B. I validated the code as well by running with Option B in eclipse and it works without any compilation error, where as in the Self Test Answers Option A is marked as correct. For the Option B it says, because List is an interface, so you cant say new List(). The new List thing happens in Option A rather than Option B

Which statements could be inserted at // INSERT DECLARATION HERE to allow this code to compile and run?

public static void main(String[] args) {

  // INSERT DECLARATION HERE
  for (int i = 0; i <= 10; i++) {
    List<Integer> row = new ArrayList<Integer>();
    for (int j = 0; j <= 10; j++)
      row.add(i * j);
    table.add(row);
  }
  for (List<Integer> row : table)
    System.out.println(row);
  }

  A.      List<List<Integer>> table = new List<List<Integer>>();
  B.      List<List<Integer>> table = new ArrayList<List<Integer>>();
  C.      List<List<Integer>> table = new ArrayList<ArrayList<Integer>>();
  D.      List<List, Integer> table = new List<List, Integer>();
  E.      List<List, Integer> table = new ArrayList<List, Integer>();
  F.      List<List, Integer> table = new ArrayList<ArrayList, Integer>();
  G.      None of the above

P.S : I have the Indian edition hardcopy book.

Many thanks
Sourabh

I think you are correct, but maybe late to the party because the Java7 exams are now pretty old. I don't know whether they are still current.
