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.
