I don't know why I was trying to use variables from another class instead of the methods. Next to get each node from the list you must iterate the list using the mechanisms provided:įor (int i = 1 i, that doesn't limit my Linked List to string types only right? Isn't it the LList that manages that (and because it's empty means it has no type right?)Īs for the loop: Ah right. Simply because you didn't instantiate the object to a type -> LList a = new LList() Rico Felix wrote:You are getting the messages: Note: Recompile with -Xlint:unchecked for details.Īnd when I run it just use jGRASP. Note: DriverWilson.java uses unchecked or unsafe operations. The problem is, when I try to compile the driver, I get the following error: Private Node(T dataPortion, Node nextNode)// PRIVATE or PUBLIC is OK Private Node(T dataPortion)// PRIVATE or PUBLIC is OK If ((givenPosition >= 1) & (givenPosition = 1) & (givenPosition 1) // traverse the chain to locate the desired nodeįor (int counter = 1 counter < givenPosition counter++) Public boolean replace(int givenPosition, T newEntry) Return result // return removed entry, or LastNode = nodeBefore // last node was removed Result = nodeToRemove.getData() // save entry to be removed tNextNode(nodeAfter) // disconnect the node to be removed Node nodeAfter = nodeToRemove.getNextNode() Node nodeToRemove = nodeBefore.getNextNode() Node nodeBefore = getNodeAt(givenPosition - 1) If ((newPosition >= 1) & (newPosition = 1) & (givenPosition 1 Public boolean add(int newPosition, T newEntry) // OutOfMemoryError possible Node newNode = new Node(newEntry) // create new node Public void add(T newEntry) // OutOfMemoryError possible Public final void clear() // NOTICE clear is not final in interface and that is OK Private Node lastNode // tail reference to last node Private Node firstNode // head reference to first node Public class LList implements ListInterface The chain has both a head reference and a tail Frank M. ** Retrieves all entries that are in this list in the order in whichĪ class that implements the ADT list by using a chain of nodes. ** Sees whether this list is true if the list is empty, or false if not */ ** Gets the length of this the integer number of entries currently in the list */ ** Sees whether this list contains a given anEntry the object that is the desired true if the list contains anEntry, or false if not */ The list is empty, givenPosition getLength() */ The desired a reference to the indicated entry or null, if either ** Retrieves the entry at a given position in this givenPosition an integer that indicates the position of List is empty, givenPosition getLength() */ Position true if the replacement occurs, or false if either the The entry to be newEntry the object that will replace the entry at the ** Replaces the entry at a given position in this givenPosition an integer that indicates the position of The list was empty, givenPosition getLength() */ The entry to be a reference to the removed entry or null, if either Position are at the next lower position within the list,Īnd the listÕs size is decreased by givenPosition an integer that indicates the position of ** Removes the entry at a given position from this list.Įntries originally at positions higher than the given Public boolean add(int newPosition, T newEntry) Position of the new newEntry the object to be added as a new true if the addition is successful, or The listÕs size is increased by newPosition an integer that specifies the desired ** Adds a new entry at a specified position within this list.Įntries originally at and above the specified positionĪre at the next higher position within the list.

That being said, heres the driver so far: My job is to create a driver, or a demo class that showcases these operations.

The Llist and ListInterface classes are perfect (as I didn't create them, someone professional did). I have this ListInterface class that has operations for my linked list and a LList class.

Here is a brief (and somewhat silly) anycodings_java example to demonstrate: import java.io.So. If the class being anycodings_java returned must be cast to a type based on anycodings_java generics, you can get this warning. If you use classes that implement anycodings_java an interface like Serializable, often anycodings_java you will call methods that return anycodings_java objects of the interface, and not the anycodings_java actual class. I just want to add one example of the anycodings_java kind of unchecked warning I see quite anycodings_java often.
