The other primary data structure characteristic you’ll want to look for is how the data structure organizes its data.
The same goes for data structures but here the “objects” are items (data values) that the structure stores and how those are related or connected to other items in the same structure. In object-oriented programming, we usually think in terms of objects and how certain objects relate to, or use, other objects.
The characteristics of data structures that most often influence these tasks are how the data structure lays out its data in the computer’s memory. Generally, the tasks you’ll want to do on your data are:ĭepending on which of these tasks you’re going to want to do most, you will choose a data structure that makes that task easier, faster, and more efficient. We all like it when things are easier to do, right? I do. The way you contain and organize your data helps determine how easily you can do certain tasks. So data structures help you store multiple values, right? What’s special about that? This allows you to keep the data together as you pass it around your program and do different things with it. It’s because data structures can hold more than a single value, organize that data, and allows you, dear developer, to perform operations on them. So if variables and constants store data, why aren’t they data structures? I’ll spare you the snark this time it was too obvious. As their name implies, the value that a variable contains can be changed, or varied - see what I did there? Constants are like variables because they store a value, but can’t be changed.

Okay, so one of the first things you learn when starting to code is how to store data, usually a simple value like a string or number, in a variable. Simple, right? But what does that actually mean? The “tl dr” version is that data structures are ways to store data. So, What the Heck Are Data Structures Exactly?
What you should aim for is to have a good understanding of what data structures are, which ones are “must-know,” be familiar with some uncommon ones, and know how to compare them so you pick the best solution. In all honesty, however, you probably don’t have to dive into the nitty-gritty details underlying each data structure. If you haven’t started your self-teaching (or other means, I’m not judging) journey yet, this post might help you get started. Given the title of this post, naturally, I’ll be talking about data structures. These two topics typify a computer science education to those who don’t have one. Your ability to translate pseudo-code into working code will come in very useful as you can truly understand the workings of the algorithms and data structures and can implement them in test applications.The two concepts that seem to cause the most feelings of inadequacy in beginners are data structures and algorithms. Once you feel you have a good grasp of your language of choice, moving on to Algorithms and Data Structures will not only be easier but more enjoyable. This will also help you develop the skills necessary to work with algorithms and solve them. Sourceforge is great for this.Īlso, if you enjoy mathematics, Project Euler is an excellent way of learning Java (or any other language as the challengs can be solved in any language). I would then recommend some practice to fully grasp the language, either by working on some small personal projects (simple text games, utilities, etc.) or by studying some open source code.

This free online Java Textbook is great as it can be viewed online, or offline by downloading a free PDF version. The Sun Tutorials are great as they cover a large amount of material, both beginner (see the Language Basics section) and advanced. It is important to be able to read pseudocode and translate it into actual working code. or Data Structures, as it gives you a deeper understanding of the inner workings of the algorithms.

It is useful to be familiar with a programming language when studying any subsection of the software engineering realm, such as A.I. Although Algorithms and Data Structures are an important part of programming, they are not the only one. I would personally reccomend you learn Java, although most programming languages will do.
