Learn about different Java versions along with different Java technologies, such as Gradle and microservices.

Android Development with Java

In this module, we'll learn and compare the different versions of Java. This will help us better understand Java and will also help us get started with the basics of application development.
We'll cover the latest in Java up to version 17—cloud and microservices, build, testing, and web frameworks as well as and reactive programming in Java. 
In the end, we will also get to work with gradle and the state of concurrent programming in Java.

The All-in-One Guide to Java Programming

## What is Java Development Kit (JDK)?
The core class type included in Java is called the JDK. It includes all the basic tools we would need in a modern application, including everything from collection types and queues, to web sockets, to files and image processing.

As an object-oriented language, methods and properties are organized into classes that are organized in packages. Each Java class should be defined in one file named for that class. The classes under `java.lang`, such as `String`, are always available. Otherwise, we would need to explicitly import the classes using an import statement at the top of our Java file. An instance of a class is called an **object**. All objects are passed by value. Unlike in C, we cannot modify a reference pointer.
