i need same of help

Hi every body
How are you??
i need same of help plz
Could anyone solve for me this problem??
thank you for your help :)

1. Create your own version of the Java program to implement a linked list as explained in class.

2. Create a Java program for doubly linked lists and provide input and output.

3. Analyze examples with generic classes given in class used in building linked lists. Make your own example.

Well, it's hard to do any of that without being in your class? :)

Ofcourse...

Try to attempt an effort..... There are experts here that are ready to help you out....(problem about your code.)

its an assignment if you need to attemt the lecture i will

http://www.nmehic.com/csci260/Lectur...Final%20SQ.ppt

this is the lecture

think you again for your help

Like Sukatoa, said try this yourself, first. I will gladly help you, but give this a honest attempt. Understanding Linked-list is really important if you plan on continuing programming.

this is my code what the wrong with it

public class DoublyLinkedList
{
public static void main(String args[])
{
DoublyLinkedList<Integer> list = new DoublyLinkedListinkedList<Integer>();
list.addHead(new Integer(1));
list.addHead(new Integer(2));
list.addTail(new Integer(9));
list.addHead(new Integer(3));
list.addTail(new Integer(11));
list.add(2, new Integer(0));
System.out.println(list);
list.remove(list.size());
System.out.println(list);
}

}

Lots of errors I can found there pal. Here what you have to do.

Code:

---

import java.util.LinkedList;

public class DoublyLinkedList {

    public static void main(String[] args) {
        LinkedList <Integer> list = new LinkedList<Integer>();
 
        list.add(new Integer(1));
        list.add(new Integer(2));
        list.add(new Integer(9));
        list.add(new Integer(3));
        list.add(new Integer(11));
        list.add(2, new Integer(0));

        System.out.println(list);

        list.remove(0);
        System.out.println(list);
    }

}

---

Still you have lots of things to learn there.

thank you very much for your help

        list.add(2, new Integer(0));

        System.out.println(list);

        list.remove(0);
        System.out.println(list);
    }

}

how does this programme work

can you tell me each code how work plz

hi
i have this programme i don’t know why does not work with me

class Queue<T> {
private LinkedList<T> items = new LinkedList<T>();
public void enqueue(T item) {
items.addLast(item);
}
public T dequeue() {
return items.removeFirst();
}
public boolean isEmpty() {
return (items.size() == 0);
}
public void addAll(Collection<? extends T> collection) {
// Add all the items from the collection to the end of the queue
for ( T item : collection )
enqueue(item);
}
}

First LinkedList is declared and initialized.

Code:

---

LinkedList <Integer> list = new LinkedList<Integer>();

---

Here you have to define the generic to avoid compiler warnings. Generic is depend on the LinkedList element type. Here it is an Integer. Then populate the linked list. You can do it in different ways.

Just add elements there.

Code:

---

list.add(new Integer(1));

---

Here actually no need to instantiate a int value. Simply add.

Code:

---

list.add(1);

---

Or you can define the index that where you want to add the element.

Code:

---

list.add(2, new Integer(0));

---

But you can't skip index there. Then remove element,

Code:

---

list.remove(0);

---

Remove the 0th element of the list.

I don't know what you are trying to do. See that your class declaration also incorrect. And defining generics for LinkedList too.

It's much better to do some work with basis of Java, then try some applications like this.
