Our textbook describes how to implement an array list using a dynamic array. The following code segment adds an element to an array list that is implemented using a dynamic array. But, the code segment has an error in the code. Which line has an errors? Choose one. 1 public void add(int i, E e) throws IndexOutOfBoundsException { 2 if (i < 0 || i >= n) 3 throw new IndexOutOfBoundsException("Illegal index: " + i); if (n == data.length) 5 resize(2* data.length); // double the capacity of array 6 for (int j=n-1;j>= i; j--) 7 datalj+1] = data[j]); 8 dataļi] = e; 9 n++; 10 } In the above code: • data [] is the array • i is the index of the location in the array where new element is added • e is the element to be added • n is the number of elements currently in the list • The resize method in line 5 doubles the size of the array data O a. Line 6 O b. Line 2 O. Line 4 O d. Line 7
