Though this topic is a very deep one, we’ll give you a concise overview of OOP. Unlike some other toolkits that merely provide bindings to native components and APIs, Codename One’s UI component library is light-weight and truly cross-platform. This provides 100% code reuse across platforms, not only for business logic, but for the UI also. While it’s the youngest programming language out there, it’s proven to be a powerful one with robust features and clean code.

It contains a wealth of Java content, and it thoroughly covers libraries, collections, lists, queues, OOP, maps, and other topics. About 80% of its Java course involves hands-on activities, so what you learn in theory is put to the test immediately. There are more than 1200 activities in a sequence of increasing difficulty to ensure that you continue to learn and keep track of your development via a virtual mentor. It’s time to choose where you’ll learn it after figuring out what you need to know.
Java’s long-standing presence, extensive libraries, and broader ecosystem make it a reliable choice for large-scale, complex systems, especially where legacy integration is vital. Since Gradle allows the use of a build cache to reuse task outputs from previous runs as well as other optimizations, it has high performance. Just like Java itself, NetBeans is another product from Oracle Corporation. It’s an IDE designed for the Java language, and is completely free.

Get going with our crush course for beginners and create your first project. Now that you understand the basics of Android Studio, it is time to finally make your first Java Android app.
For example, we could use com.mamlambo.aquarium or com.ourclient.project.subproject as our package name to keep track of our fish-related classes. Class hierarchies, such as our fish classes, can then be organized into packages. A package is simply a set of classes and interfaces, bundled together. Generally speaking, a class will be defined in its own file, with the filename matching the class name (e.g. Dog.java). Each Android application runs on the (Linux-based) operating system using a different user account and in its own instance of the Dalvik VM. Module 2 provides an overview of Android Studio, explaining how to install it and apply it to develop a simple app using basic Java and Android features presented in this MOOC.
Let’s pretend we are developing a Java application to simulate an aquarium. Module 1 summarizes the organization of the MOOC and the topics it covers. It also discusses the MOOC prerequisites, workload, and learning strategies needed to complete the MOOC successfully.
In this article, we’ll review why Java is still many developer’s go-to programming language and how it stacks up against other popular languages for Android, like Kotlin. CLDC is a Java Community Process effort that has standardized a portable, minimum-footprint Java building block for small, resource-constrained devices. CLDC runs on top of Sun’s K Virtual Machine (KVM) that is provided as part of this release. A project is a collection of everything you’ll need to get your Android app off the ground, up, and operating.
There is a wide cluster of languages, systems, SDKs, and instruments that you can use for mobile app development. Nowadays, Java is considered the most common and efficient programming language for Android app development. Java is a programming language independent of all platforms and can be used on a wide variety of operating systems, including Android, iOS, Windows, and more. This is one of the key benefits and reasons why using Java to develop Android apps is such a popular choice. Compared to other languages that don’t have platform independence features, it follows the “write once, run anywhere” principle. Such development flexibility is what makes this technology so widely appreciated.

For this reason, iOSSkipSigning is set to true and we do not make use of the releaseAndroid gradle task. You can, however, provide the appropriate accommodations to produce signed apps. Android Studio provides a code editor called IntelliJ IDEA, which interprets Java as you type, providing handy code coloring and formatting as well as showing many types of errors as you go. Often, you can click on the error and have IntelliJ IDEA automatically fix a typo, add an import statement, or provide a method stub for you, saving lots of typing. The Java compilers convert your code from human-readable Java source files into something called “bytecode” in the Java world.
In this section, we will explore both the advantages and disadvantages of using Java for mobile application development. For for your mobile application development requirements, you should hire the best Android app developers, who can build well-suited app for your business.
