Don't worry too much about choosing the correct Java version and JDK package when you are just starting out. It's also not hard to switch to a different JDK in the future if you find you need to. For example, Jave EE is the standard platform with additional tools useful for enterprise application development such as Enterprise JavaBeans or support for Object Relational Mapping. If you download Java EE or Java ME, you will get the standard edition with it. Generally, each JDK version contains Java SE. Novice developers are sometimes unsure which package is correct for their project. The available packages are Java Enterprise Edition (Java EE), Java Standard Edition (Java SE), and Java Mobile Edition (Java ME). Packages are Java Development Kits that are targeted for different types of development. In addition to choosing your Java version, you will also need to select a Java package. Java maintains backward compatibility, so we'll just download the latest release. Java 8 is the version most commonly in use, but as of this writing Java 11 is the long-term support (LTS) release. When you download your JDK, you will need to select the version of Java you want to use. Getting Java setup in your development environment is as easy as downloading a JDK and adding it to your classpath.

First, I'll show you how to download and setup a JDK in your development environment. java files-which are plain text-and rendering them into executable.

The compiler is the software program capable of taking raw. In addition to the JRE, which is the environment used to run Java applications, every JDK contains a Java compiler.

Everyday definition: The JDK is a software package you download in order to create Java-based applications.

Technical definition: The JDK is an implementation of the Java platform specification, including compiler and class libraries.

Just as we did with my recent introduction to the Java Virtual Machine, let's consider the technical and everyday definitions of the JDK: Figure 1 shows how the JDK fits into the Java application development lifecycle.
