Consider the definition of the add method that adds an entry to a list at a given position and appears in Segment 14.11. Replace the statements that execute in case 1 with the following ones:

if (isEmpty() || (newPosition == 1)) // case 1{  firstNode = newNode;  newNode.next = firstNode;}

a. What is displayed by the following statements in a client of the modified LList?

---

ListInterface myList = new LList();myList.add(1, "30");myList.add(2, "40");myList.add(3, "50");myList.add(1, "10");myList.add(5, "60");myList.add(2, "20");int numberOfEntries = myList.getLength();for (int position = 1; position <= numberOfEntries; position++)System.out.print(myList.getEntry(position) + " ");

b. What methods, if any, in LList could be affected by the change to the method add when they execute? Why?
