5 Minute Beginner’s Guide to Java’s Linked List Data Structure

What is a Linked List?

Often used to implement other data structures, such as stacks, queues and trees, a linked list is a linear data structure. Forming what can be thought of as a linked chain, a linked list is a sequence of nodes. Each node stores its own data and a pointer (address) to the location of the next node. The last link in a linked list points to null, indicating the end of the chain.

Is it like an array?

Although similar to an array in its approach to sequence and order, a linked list is not restricted to a declared number of elements. Also unlike an array, where each array element is stored contiguously (each element has a consecutive memory address), linked list elements are not stored contiguously. Therefore, in contrast to an array, linked list elements can be inserted and removed without reallocation of memory.

Costs: Array vs. Linked List

Big-O notation is a way of describing (and comparing) how many operations an algorithm (or, in this case, a data structure) needs to perform some task.

Cost of accessing an object:

Array == O(1) vs. Linked List == O(N)

Cost of insertion/deletion:

Array == O(N) vs. Linked List == O(1)

Array’s are quicker at accessing objects, but Linked List’s are quicker at inserting and deleting objects.

For more information on Big-O notation check out the Big-O Cheat Sheet. It’s a great resource.

Important Points to Remember About a Linked List

  • Each link in a linked list is an object (also called an element, node, etc.).
  • Each object holds a reference (an address) to the location of the next object.
  • The last link in a linked list points to null, indicating the end of the list.
  • A linked list can grow and shrink dynamically at run-time (the time at which your program is running, after it has been compiled), limited only by the amount of physical memory available.

Advantages of a Linked List

  • Insertions and deletions are quick.
  • Grows and shrinks as needed.

Disadvantages of a Linked List

  • Random access is slow. Objects in a linked list must be accessed sequentially, therefore, it can be slow to access a specific object.
  • Memory is a concern. Each object in a linked list requires data as well as one (or more) pointers to other objects in the linked list. Using significantly less memory, each object in an array only requires data.

When to Use a Linked List?

  • You don’t need random access to any specific elements.
  • You need to do constant insertions and deletions.
  • You’re not sure how many items will be in the list.

Doubly Linked Lists

A doubly linked list (or double linked list) is a more complex implementation of a linked list. It requires more memory, but accessing objects is easier. Accessing from the first or leftmost object (called the “head”) costs as much as accessing from the last or rightmost object (called the “tail”). Each object in a doubly linked list contains two references (unlike one in a basic linked list) to the previous and to the next node in the sequence.

Let’s Make a Linked List in Java

Java, as a programming language, focuses on code reusability through classes and objects. A class is basically a blueprint or template for an object. Though you can build your own custom classes for a linked list implementation, Java does offer a convenient built-in LinkedList class.

For this short example, Java’s built-in LinkedList class is used. It should be noted that, according to the the official documentation, all operations offered by the built-in class perform as expected for a doubly-linked list implementation. Additionally, the LinkedList built-in class is technically a list implemented using a linked list. In contrast, Java’s built-in ArrayList class is technically a list implemented using an array. Choosing which to use in your program is dependent on both your goals and memory availability.

Example: Make an empty linked list, store the values 1, 2 and 3 in it and print the values out.

When using Java’s built-in LinkedList class, you should start by importing the LinkedList class and creating an empty linked list. For this example, an empty linked list of integers is created.

There’s a variety of built-in methods that you can use when working with your new linked list. The code snippet below adds 1, 2 and 3 to the linked list.

It’s also very simple to iterate over a linked list and print out all the data.

For additional information on Java’s built-in LinkedList class, check out the official documentation.

Topic

First of all: Congratulations for releasing GeoGebra 3.2. At the moment I’m exploring the capabilities of the new spreadsheet functions, especially for exploratory data analysis.

With introducing spreadsheet view some problems arise regarding the consistency / logic of bidirectional or multidirectional representation of objects.

    Firstly: You create a list of points from cell area «A1:B12». The list of points creation seems to follow this logic: GeoGebra creates 12 points as invisible auxiliary objects (algebraic view), which are visible in geometric view as unique points and visible as a list of points as an dependent object (algebraic view).

The list is actually depending on the (auxiliary) points (If you click on «Properties» you will find a Definition like «P_1, P_2, P_3, P_4, P_5, P_6, P_7, P_8, P_9, P_<10>, P_<11>,P_<12>«), rather than depending on the area of cells it was created from.

Suppose you’d like to redefine this list: The only way this can be handled is via editing its definition in the algebraic properties dialogue by manually deleting or adding points, or via algebraic list-operations.

A true bidirectional connection to the spreadsheet view would be referencing the according area within the table (e.g. «A1:B12», which is used when creating a list of numbers from spreadsheet view).

There is no easy way of redefining a list of points using spreadsheet references (e.g. add the area «A13:B20» to the list of points).

This might not seem to be a big problem at first glance, as you could use list operations (List1+List2), it is a problem if you create objects depending on that list and want to change these objects in one step by changing the original list (eg. to «A1:B20»).

Secondly you can easily combine list (of points or numbers) using «Union» or «Intersection», but why can’t we have a similar command for creating the difference quantity of two sets/lists? It’s quite easy to add elements to a list, but removing elements from a list is only simple, if these elements are undefined (using «RemoveUndefined»). Such functions could be very useful e.g. to manipulate best fit lines by removing sets of points that are stored within a list of points. Maybe this could be accomplished using «KeepIf[Condition, List]», but the help file doesn’t point out if this function can be applied to lists of points or only to lists of numbers (the example given there is a list of numbers).

Moreover I’d highly appreciate a function that allows for creating a list of points from two lists of numbers with the same length. An example: Suppose you have a list of (x,y) data and you want to resale x- and y-values. You could create two lists (x-values, y-values). You can easily add a number to each element in the list (list+number) or multiply each element in the list with a number (list * number). But there is no easy way of combing the resulting lists into a list of points.

Being able to do this would also fix the above problem, as you could delete the x-value of a point using «KeepIf» from the list of x-values and the y-value from the list of y-values and afterward create a new list of points.

  • Lastly while it is easy to create a list of numbers, a list of points or a matrix from the spreadsheet view, I found no similar way to do it the opposite way. You can easily input a number, variable or point into the spreadsheet view, you can input a matrix, list of numbers or list of points into a single cell, but there seems to be no way of entering a matrix, list of numbers or list of points into multiple cells at once.
  • HTML Lists

    HTML List Example

    An Unordered List:

    • Item
    • Item
    • Item
    • Item

    An Ordered List:

    1. First item
    2. Second item
    3. Third item
    4. Fourth item

    Unordered HTML List

    The list items will be marked with bullets (small black circles) by default:

    Example

    • Coffee
    • Tea
    • Milk

    Unordered HTML List — Choose List Item Marker

    The CSS list-style-type property is used to define the style of the list item marker:

    Example — Disc

    • Coffee
    • Tea
    • Milk

    Example — Circle

    • Coffee
    • Tea
    • Milk

    Example — Square

    • Coffee
    • Tea
    • Milk

    Example — None

    • Coffee
    • Tea
    • Milk

    Ordered HTML List

    The list items will be marked with numbers by default:

    Example

    1. Coffee
    2. Tea
    3. Milk

    Ordered HTML List — The Type Attribute

    Numbers:

    1. Coffee
    2. Tea
    3. Milk

    Uppercase Letters:

    1. Coffee
    2. Tea
    3. Milk

    Lowercase Letters:

    1. Coffee
    2. Tea
    3. Milk

    Uppercase Roman Numbers:

    1. Coffee
    2. Tea
    3. Milk

    Lowercase Roman Numbers:

    1. Coffee
    2. Tea
    3. Milk

    HTML Description Lists

    HTML also supports description lists.

    A description list is a list of terms, with a description of each term.

    The tag defines the description list, the tag defines the term (name), and the tag describes each term:

    Example

    Nested HTML Lists

    List can be nested (lists inside lists):

    Example

    • Coffee
    • Tea
      • Black tea
      • Green tea
    • Milk

    Note: List items can contain new list, and other HTML elements, like images and links, etc.

    Control List Counting

    By default, an ordered list will start counting from 1. If you want to start counting from a specified number, you can use the start attribute:

    Example

    1. Coffee
    2. Tea
    3. Milk

    Horizontal List with CSS

    HTML lists can be styled in many different ways with CSS.

    One popular way is to style a list horizontally, to create a navigation menu:
