2 Websites & 2 Apps That Can Help When Learning Java Programming

learn java programmingThere are plenty of people I know who’d like to know how to program, yet they’re confused by how to start and what the general ideas of programming are. In addition, there are a large number of programming languages Which Programming Language Should You Learn For Software Development? When starting on the path of programming, it’s important you invest your time wisely in choosing to learn something that will both benefit you in the immediate future with visible results on your platform of... Read More to choose from, so choosing the right one to start out with may be a little difficult for the inexperienced programmer. This article will help you get started with a relatively easy to learn language.


Why Learn Java Programming?

Java is my programming language of choice when trying to learn the concepts of programming. This is because Java is very cross-platform, has a fairly readable syntax (compared to other languages), and there are many tools that can make developing in Java a fairly easy task. Before we begin, make sure that you have the JDK installed, as you won’t be able to do a thing without it.

Parts Of Java

Java programs are separated into classes. Technically each class is its own program, but you can work with numerous classes to make a larger, more complex program while maintaining good code organization. At least one of those classes needs to be the main class, or contain a main method. A method is a chunk of code that executes when you simply call the name of the method. The main method is required as Java looks for this method to start the program. You can pass parameters to other methods if you’d like, allowing the method to take input and do something with it.


More than likely you’ll also need to store information at certain points. These are variables, or sometimes called fields, that hold the information. You have to specify the type of variable so that Java knows what you’re trying to hold. This includes things like true/false (boolean), numbers (int, long, double, etc.), and much more. As Java can support object-oriented programming, you can even hold instances of a class in a variable.


As an example, here is a class that would simply print out the number 6 onto the screen:

public class makeuseof
public static void main (String args[])
int myNum = 6;

2 Recommended Applications

There are two applications I would recommend that will help you during your programming adventures.

For those who want to have a good enough editor to do the nitty gritty programming, I recommend using Geany Geany - A Great Lightweight Code Editor For Linux Surprisingly, Linux doesn't offer that many good IDE's (Integrated Development Environments). I believe this is because back in the day most Linux programmers took out good old Notepad (or gedit in this case), and started... Read More . It is available for all operating systems, is relatively lightweight, and simply gets the job done. There are indeed lots of other editors that people can choose from, and they’re welcome to use those instead, but my recommendation stays with Geany.


2 Recommended Websites

There are a couple of websites that can help you out if this introduction didn’t make much sense.

First is “Javanotes 6.0” which provides a much more lengthy but complete explanation of basic Java programming concepts. Here you’ll find loads of information and some programming exercises. If you have the time for it, it’s a great read.

Lastly, you can also check out HowStuffWorks’ page on Java. It also includes some information and guides you to making your first program. This is another interesting read, and involves a different first problem than the traditional “Hello World” example.


Getting started with Java isn’t as hard as it seems. With some time and practice you’ll get the hang of it, and from there you can build more complex programs that provides more functionality. Additionally, if you master the programming concepts, it’ll be easier to learn other programming languages as a large portion of the learning process is simply different syntax.

    Thank you for this fine introduction explaining what I might expect if I should make the decision to embark on a huge learning experience of how to become a programmer, with the ultimate goal of knowing how to create my own android apps. It's great to have found such an easy to understand explanation of what I can expect should I decide to try to learn java.
    I did take one course in college that by the end, was able to write a very simple program in BASIC language.
    I think your work here has removed most of the fear and intimidation I used to feel when considering to see if I may be capable of learning everything necessary to one day crate my own android apps, which ever thing I have read tells me the first step is to learn java, as a good starting point.... Now you have explained how much work it's going to take tho learn java and after reading your info, I feel you have explained the BEST and most efficient and least Scary route to learning java.
    Thank you very much for the info bro, as you have made me less afraid to try, and even excited about the adventure such that I'm finally ready to do it and ready to go! Your info is the Best I've ever seen that Clearly explained what I should expect and whether I can handle the ambitious plan or if I just won't be able to follow and just be wasting my time. Your info and explanation makes me feel that I can probably get started and be able to actually do this thing, and that learning to become a programmer is not the impossible task I was afraid of that has been holding me back for many years now.
    I am retired and would love to full my spare time becoming an expert in java with the ultimate goal of making and selling my own android applications.
    Thank you for this clear explanation if what it's going to take to undertake this endeavor, or at least to get started by learning programming in the language of java. Thanks for the encouragement and clear explanation of what last ahead of me.
    Sincerely and gratefully,
    Florida, USA

    About how long will it take to be able to learn this fairly well?

      It really depends on how much time you're willing to spend on it. I learned a decent amount in my Computer Science class in high school which focused solely on Java. After the school year I knew enough to read code in actual applications that you can find and understand it.
