Psychonaut 0 #1 September 25, 2010 Can anyone help me out? You can see in LinkList.java I need to build the insertAfter and insertBefore. What my mind see's, for insertAfter to begin with, is something like this.. public void insertAfter(long dd) { long reference = current.dData; if (previous == null) { current = current.next; //Move current over one to make room for insert previous = reference; //Insert given number } else { previous = reference; //Insert given number } } Stay high pull low Quote Share this post Link to post Share on other sites
Arvoitus 1 #2 September 25, 2010 Disclaimer: I don't write Java for a living and I'm tired. So if you fail your class because you decided to outsource your homework to a discussion forum then its your fault and yours alone. public void insertAfter(long dd) { // insert a new node after current node; Node newNode = new Node(dd); // if current is not null, don't change it; if(current != null){ newNode.next = current.next; current.next = newNode; } //otherwise set current to new node. else{ newNode.next = null; current = newNode; previous.next = current; } } public void insertBefore(long dd) { // insert a new node before current node, always set current to the new node Node newNode = new Node(dd); newNode.next = current; if(previous == null){ current = newNode; first = current; } else{ current = newNode; previous.next = current; } Your rights end where my feelings begin.
