2D Array Nested Loop Traversal

What is printed when the following code segment is executed?

String[][] letters = {{"A", "B", "C", "D"},
                      {"E", "F", "G", "H"},
                      {"I", "J", "K", "L"}};

for (int col = 1; col < letters[0].length; col++)
{
    for (int row = 1; row < letters.length; row++)
    {
        System.out.print(letters[row][col] + " ");
    }
    System.out.println();
}
