Question
What is the purpose of the following method? Assume that both q1 and q2 are not empty.
public class QueueEx
{
public static void method1(ArrayQueue<Integer> q1, ArrayQueue<Integer> q2)
Iterator<Integer> iter1 = q1.iterator();
while (iter1.hasNext())
{
int a = iter1.next();
if (a > q2.peek() )
q2.offer(a);
}
}
}
O a. All elements of q1 which are greater than the first element of q1 will be added to q2.
O B. All elements of q1 which are greater than the corresponding elements of q2 will be added to q2.
Oc. All elements of q2 which are greater than the first element of q1 will be added to q1.
O d. All elements of q1 which are greater than the first element of q2 will be added to q2.
