Question

Write a method removeFront that takes an integer n as a parameter and that removes the first n values from a list of integers. For example, if a variable called list stores this sequence of values:

[8, 17, 9, 24, 42, 3, 8]

and the following call is made: list.removeFront(4); it should store the following after the call:

[42, 3, 8]

Notice that the first four values in the list have been removed and the other values appear in the same order as in the original list. You may assume that the parameter value passed is not negative and not larger than the size of the list inclusive. If the parameter value passed is 0, the list should be unchanged by the call.

Explanation / Answer

void removeFront(int n) {
   Iterator i = this.iterator();
   while (n > 0 && i.hasNext()) {
       i.remove();
       --n;
   }
}
