Java’s claim to fame is its compatibility across any platform, meaning that regardless of the operating system that you are using, Java can be written for it. A good example would be the different operating systems that we use for computing, whether it be a Windows computer, a Mac, a Linux machine, or an Apple, Windows, Android, or Blackberry based mobile device, Java works perfectly with all them.

Not only that, but this all requires that just one set of code be written for all of them, instead of needing different variations of the code to suit different computing environments. This is what has really driven the popularity of Java to where it is today, being pretty much ubiquitous in the world of computing.

In order to run Java, you need a Java plugin, but this isn’t something you buy, it already comes pre installed with just about every computer, unless you are using a custom made one where the builder just hasn’t loaded up the popular plugins yet.

So in other words, Java is free, you almost certainly already have it, and if you don’t you can very easily get it for free just by going to the Java website. It will also allow you to test your version to make sure it’s the latest one, and if not, update it. You can also allow for Java to automatically update, which is the preferred method.

From a user’s perspective, Java isn’t something you ever will be aware of operating on your machine or device, other than the fact that you may notice that you will be downloading updates to it from time to time. So if you do have automatic updates enabled, once in a while when you turn on your machine, if it’s a desktop, you will see a prompt to download an update.

Other than that, you won’t ever notice it or even know it’s there. Flash is somewhat like that, although Flash does tend to crash once in a while, and you may have issues with web pages in particular, because Flash is software, even though it’s embedded software and you don’t generally see it.

Java on the other hand is a programming language, used to write various software programs, and the Java software on your computer that you install and maintain allows it to read and speak the Java language so it can run programs and software written in Java.

Java’s Role In Online Casinos

Should you think about writing for a specific operating system, then this presents limitations. For example, if it’s a Windows program and you have something other besides a Windows computer, a Mac or a Linux machine, or an iPhone or an Android device, you aren’t likely to be able to run it. This often creates unnecessary hurdles.

Online casinos might choose to write programs for all of the diverse operating systems out there, and some do cover off the major ones, but it is costly to write and maintain software programs, and when you need to write and sustain several ones, these costs are multiplied significantly. It's a complex and resource-intensive task.

Ideally, online gaming sites would ideally offer just one version, and no software would need to be offered to download, and players could simply go to their site and start playing, regardless of what operating system or device they happen to be using. Convenience becomes a major advantage here.

Java, due to its cross platform compatibility, is helping make this dream a reality. It doesn’t matter what system you are running if you have Java capability, and just about every computing device on Earth already does, so the potential is strong for online casinos to realize this ambition. This opens up many possibilities for innovation.

We’ve progressed a long way toward achieving this already in just the past couple of years, utilizing not only Java but other technologies such as Flash and HTML5, and the goal is to remove downloads completely and also render irrelevant what type of device people are using to engage. Technology continues to advance rapidly.

The primary aim here is to not only offer users instant play, on whichever device they want to play on, but to also deliver a top notch gaming experience, without any compromise. In fact, by focusing all of their resources to a single format, which might happen someday soon, this will enable them to offer even higher quality experiences than we see today. The future looks promising for digital entertainment.

Java and the No Download Casino Experience

We’re already seeing this happen at some sites, and no download casino play has gone from a clearly inferior secondary option to playing a much more prominent role in the business. Some sites, the more innovative ones that were born during this transformation of the last couple of years that we’ve seen, have already taken the big step of dispensing with downloads entirely, while at the same time offering users very high quality online gaming experiences.

A lot of this movement is powered and run in the Java Runtime Environment, although users don’t even have to worry about whether or not they are playing in Java, it just runs in the background and helps make such things possible.

As the technology continues to improve, we may expect better and better no download casino experiences, as well as more and more selection of games offered in it. In fact, the days of downloaded casino software are probably numbered, and this also includes apps written for specific mobile devices.

As we move closer and closer toward this ideal situation for both online casinos and online casino players, we can all be thankful that Java is playing a leading role in driving these positive changes to make online casino play better and better.
