Traversing and Modifying an ArrayList
Consider the following instance variable and method.
private List<String> animals;
public void manipulate()
{
for (int k = animals.size() - 1; k > 0; k--)
{
if (animals.get(k).substring(0, 1).equals("b"))
{
animals.add(animals.size() - k, animals.remove(k));
}
}
}
Assume that the animals list is initialized with the elements ["bear", "zebra", "bass", "cat", "koala", "baboon"]. What are the contents of animals after the manipulate method is executed?
A
[“bear”, “zebra”, “bass”, “cat”, “koala”, “baboon”]
B
[“baboon”, “bear”, “zebra”, “bass”, “cat”, “koala”]
C
[“zebra”, “cat”, “koala”, “baboon”, “bass”, “bear”]
D
[“baboon”, “zebra”, “bass”, “cat”, “bear”, “koala”]
