Substring Method And Singly Linked List

Jul 16, 2014

I'm still working with the singlylinkedlist data structure and trying to return a string of individual characters stored in each node. ( head--('J')---('A')---('V')---('A')---tail ) Hopefully this beautifully executed depiction to the left will clarify.

This is what I came up with after designing the algorithm w/ pen and paper. I know that I'm not accounting for the OutOfBound errors, an empty list, or an index < 0.... I will get to that.

Right now, I'm not sure why my assignment to the character array, ' chars[i] = cursor.getLink(getElement()); ' , is not working. The two methods getLink and getElement, type Node and T, respectively, exist in my Node class which is a private nested class in MySLList. Why would I be getting the following error: "The method getElement() is undefined for the type StringX" ? Is this a good design and implementation of the substring method?

public String substring(int index) {
char[] chars = new char[(getSize() - index)]; //getSize() defines the size of list in MySLList
Node cursor = null;
//Set the cursor to the node = index
if(cursor == head) {

Implementing Singly Linked List

Apr 17, 2015

I am trying to implement a singly linked list. My singly linked list, where I implemented a class named linkedlist, that I defined (this implementation of linkedlist is not the java class linkedlist, it is my own version of linkedlist):

Java Code:

public class SinglyLinkedList<E> implements LinkedList<E> {
public class Node<E> {
public Node<E> next;
public E element;
public Node(E element) {

this.element = element;
}

public Node (E element, Node<E> next) {

[code]...

But when I go to my main method to add into my SinglyLinkedList, it doesn't add anything.

Singly Linked List Not Printing Correctly

Sep 30, 2014

Its a program that creates a singly linked list that stores names and high scores and prints them. For some reason it is printing an entry extra times. Also my remove function is not working properly.

package project;
public class GameEntry implements Comparable<GameEntry> {
private String name;
private int score;
public GameEntry(String n, int s) {
name = n;
score = s;

Singly-linked List Program Challenges

Oct 22, 2014

read a text file that has some polynomials in a specific format and perform an arithmetic expression. This needs to be done using a singly-linked list to store the coefficients of the polynomials. There needs to be two methods, one that adds the two polynomials and one to multiply them. So for example suppose i had the following set of polynomials in the text file:

2+x2-3x3 and 1-x-2x2+3x3

these are represented by 2, 0, 1, -3 and 1, -1, -2, 3 respectively. The of the two polynomials is: 3-x-x2 which is represented as: 3, -1, -1

The product of the two polynomials is: 2-2x-3x2+2x3+x4+9x5-9x6

My code is just echoing the data in the text file and not actually doing any arithmetic.

import java.io.*;
import java.util.Scanner;
class Node {
public int digi1;
public int digi2;
public Node nxt;

Dequeue Of Queue Implemented Using Circular Singly Linked List With No Tail Reference

Oct 27, 2014

So I'm trying to build a queue, first in first out, (so add to the head remove from the end) using a linked list for use in another program, I'm having a problem dequeueing where the program seems to run indefinitely without giving an answer, so my suspicion is its caught in a while loop but how and why I can't figure out.

public class CircularQueuelist {
private Node head = null;
private int size = 0;
private class Node
{
int data;
Node next;
 
[Code] ....

My logic seems sound, I basically look for when the second node over from the current one I'm on is a reference to the head, and then skip the one in front of it using setting currents. next link to current.next = head, severing the link to the last node.

This is what my driver looks like, I enqueue items 1-10 and then use the iterator to make sure it worked out fine and check size, its when I dequeue that I run into a problem, the program runs indefinitely.

public class Queuetest {
public static void main(String[]args)
{
CircularQueuelist test = new CircularQueuelist();
for (int count = 0; count < 10; count ++)

[Code] ....

Implement A Set Abstract Data Type Using Singly Linked Lists

May 6, 2015

I am trying to implement product method below which returns the set representing the Cartesian product of the current set and a given set (the Cartesian product contains all ordered pairs (a, b) where a belongs to the current set, and b belongs to the given set). The product should be a ListSet <Tuple<E>> object where each ordered pair is a Tuple element. (I have a Tuple class which implements an ordered tuple)

What am I trying to do in the product method : Make 2 for loop and inside the for loop make an array of <E> then set the 2 elements of the tuple then again set tuple and add it to arrayList. how to set 2 elements of the tuple and set tuple ??

public class ListSet<E> implements Iterable<E>{
SinglyLinkedList<E> sl;
public ListSet(){
sl = new SinglyLinkedList<E>();

Linked List Queue ToString Method

Oct 21, 2014

So I have to write all the methods for a LinkedListQueue. I've got isEmpty, enqueue and dequeue working correctly (I think) but I'm having trouble with the toString method. I tried to do it recursively and it works if there is only one element in the list, but with multiple elements it throws a StackOverflowerror exception. I've tried it multiple different ways, but I can't seem to figure out how to print it out with out clearing everything. We haven't been taught StringBuilder or .append yet, which I saw a lot of as I was looking for solutions, so I can't use those.

public class LinkedQueue<T>
{
protected LLNode<T> front; // reference to the front of this queue
protected LLNode<T> rear; // reference to the rear of this queue
private T info;
public LinkedQueue()
{
front = null;
rear = null;

[Code] ....

and this is the ITD used with it, for some reason it has the "empty the queue" function as a choice but we weren't assigned that function, so just ignore it.

import java.util.Scanner;
public class ITDLinkedQueue
{
public static void displayMenu()
{
System.out.println("(1) display menu");
System.out.println("(2) check isEmpty");
System.out.println("(3) enqueue");
System.out.println("(4) dequeue");

[Code] ....

Invoking Subclass Method On Object In A Linked List

Apr 9, 2014

I am trying to put a reference to a given subclass object into a linked list, and then come back later, and invoke a method of the subclass object that is in a given spot in the linked list. This produces an error because Object does not have that method. Is it necessary to cast the object to the correct subclass every time I want to use one of its methods, or is there a way to convince the JVM to treat it as always of type MySubclass?

Writing IndexOf Method For More Than One Instance In A Linked List

Jun 7, 2014

I'm trying to write an indexOf() method that will return every time a value occurs in a linked list. I need to use my user-created linked list not the built in Java linked list. For example in a linked list of characters: "i, p, z, z, n, d, p, z" when I search for "z" it should return position variables for 3, 4, and 8. Currently what I have is obviously only returning the first instance.how I can return more than one instance?

public int indexOf(char input) {
LLNode currentNode = this.first;
int position =1;
boolean found = false;

Why Substring Method Subtract Extra 1

Sep 10, 2014

Why does the substring method subtract an extra 1?

For example:

myString = "Programming and Problem Solving";

myString.substring(0, 7) would be "Program" instead of "Program".

It's not explained in the book I'm reading and didn't see it online.

Sort Linked List Through The Nodes Of List - Data Of Calling Object

Feb 14, 2014

I have some class called sorted to sort the linked list through the nodes of the list. and other class to test this ability, i made object of the sort class called "list1" and insert the values to the linked list.

If i make other object called "list2" and want to merge those two lists by using method merge in sort class. And wrote code of

list1.merge(list2);

How can the merge method in sort class know the values of list1 that called it as this object is created in other class.

Linked List Implementation Of List Interface?

Oct 5, 2013

So we have an assignment regarding a linked list implementation of a given list interface.

In my list interface, the method contains(T anEntry) is defined.

In the LList implementation, contains is already implemented as part of getting the core methods in.

Now I am being tasked with the following:

Provide a second implementation of the method contains2(T anEntry) that calls a private recursive method

Private boolean contains (T anEntry, Node startNode) that returns whether the list that starts at startNode contains the entry anEntry.

I've written the private recursive method already. That's not an issue (at least not right now).

But what I don't understand is how startNode is supposed to be populated when this private contains method is called from the public contains2 method? contains2 only takes one parameter: anEntry. the private method takes two parameters: anEntry and startNode. How am i supposed to provide startNode when I am calling contains2?

Inserting A Set Into Linked List?

What I'm supposed to do is make a method to insert a set of Tiles to the list,i.e.,a detour(make sure that the inserted detouris compatible with thecurrent path so that the resultingpathdoesnot have any gaps). But I'm confused on how to go about doing it. I was thinking of maybe just adding 1 to the current Node.

Dynamic Linked List

Jan 30, 2014

I'm trying to implement an Office class that contains an inner class: WorkerNode. The WorkerNode class has a name attribute (String) and WorkerNode attributes for boss, peer and subordinate. The attributes of Office are manager and current which are WorkerNode references. The manager refers to the entry point of the structure and current is the current node in the structure. For simplicity, i'm going to try to limit it to 3 levels and assume that the names are unique. I've put together a Office class that containing main and provided the code I've worked on so far.

public class Office {
public static void main(String[] args) {
String name=Input.getString("input the manager's name: ");
Office office=new Office(name);

Linked List Sorting

Apr 20, 2014

I have made a node class and im trying to implement a sorting method. I must use a selection sort but with specific instructions: "Your method should not need to use the new operator since it is just moving nodes from one list to another( not creating new nodes)

this is my current implementation ..but i am instantiating new object..

public class NodeInt
{
private int data;
private NodeInt next = null;
public NodeInt(){}
//precondition:
//postcondition:
public NodeInt(int data, NodeInt next)
{
this.data = data;
this.next = next;

edit: this is the part that worked but i had it commented out so i have the previous and current declared above but didnt copy.

Searching Linked List

Apr 30, 2014

Ok here I have a code that generates 1 million random values then converts them to a string then hashcode. I then insert into a linked list and then I want to run through each hash and find it in the linked list timing each run then averaging out the time at the end.

It works great for smaller amounts of numbers it is searching for (fine under 50 thousand searches for the for loop starting at line 24 LinkedListTest.java) but when I try to do the full million searches it gives me "a Exception in thread "main" java.lang.StackOverflowError" at line 158 in List.java. Maybe im getting tired but I cannot figure out why.

// class to represent one node in a list
class ListNode< T >
{
// package access members; List can access these directly
T data; // data for this node
ListNode< T > nextNode; // reference to the next node in the list

But I have a problem in my first listNode where it ll be pointing to null, thus in the sum2List method the program checks the while condition into false and doesn't go through the loop.

Add Or Remove Will Be More Efficient By A Linked List

Jan 31, 2015

if one address point on another address. so set and get methods will be less efficient then an array, but add or remove will be more efficient by a linked list ? a linked list also inherit from queue so if i add an elemnt via "addFirst" function . where its adding the element ? to the right most or left most ?
if i have for example :

here [ ] --> [ ] --> [ ] --> [ ] -->[ ] or here

linked list its FIFO so the head will be the right most ?

Edit : its confused me a little bit but i understood now .so it will be at the left most. its actually ordered . not like the stack which is LIFO.

How To Move Along A Doubly Linked List

public Space(String name)

Recursively Reverse Linked List?

Oct 17, 2014

i tried everything but its giving me errors. i tried the for loop but its giving me something else.

this is what i have to do Write a recursive method that prints out the data elements of a linked list in reverse order.

Your method should take in as a parameter the head reference to a linked list. Then, write a recursive method that returns a count of the number of elements greater than a given threshold. You may assume that the data elements in the linked lists are ints. The parameters of your method are a reference to the linked list and a int value representing the threshold.

public class recursion3
{
public static void main(String [] args) {
char a [] = {'A', 'B','C','D','E'};
System.out.println(a);
}
public static String reverseString(String s) {
if (s.length() <= 1) {
