Programming languages are only as powerful as their libraries. Developed long after C and C++, Java incorporates many of the powerful features of those powerful languages while addressing some of their drawbacks. Java is mainly used to create Android apps (aka native apps) and desktop apps. But it's not used in programming websites-not at the time of writing this, at least. Basically, JavaScript is used to program interactivity in websites. On a website, when you click on a button to submit a form, click on an icon to toggle a hidden sidebar, or do something else that results in some visible movement in the website's UI, a JavaScript program is most likely responsible for carrying out the interaction. JavaScript is a scripting language used mainly in websites to add interactivity to the site's UI (User Interface) elements. What Is Java?ĭespite their similar names, Java and JavaScript are not the same. It’s freely available for Windows, Mac, and Linux operating systems.įor complete instructions on how to install Android Studio and its related tools, see the Android Studio user guide. Android Studio is a very popular development environment (IDE) for Java and is the preferred IDE for Android development.Īndroid Studio has its own intelligent code editor (IntelliJ IDEA) and provides a ton of features that are all geared towards helping you develop Android apps with less difficulty. To develop Android applications (or any Java applications, for that matter), you need a development environment to write and build applications. Technically, you don’t need any tools to complete this tutorial, but you will certainly need them to develop Android applications. We aren’t going to teach you to program we’re going to provide you with clear examples of commonly used Java language constructs and principles, while pointing out some Android-specific tips and tricks. If you’re new to Java or just looking to brush up on the details, then this is the tutorial for you! Getting StartedĪs far as prerequisites go, we’re going to assume you understand how to program (perhaps in PHP, JavaScript, C++ or some other language) but that you are unfamiliar with the specifics of programming in the Java language. In this tutorial, you’ll get a brief introduction to Java fundamentals, including object-oriented programming, inheritance, and more.
