We'll stick with Java SE for this tutorial, so that we can focus on the core JDK classes and technologies. Otherwise, the javac command will reject the code with a syntax error. For example, if you want to use the newer functional programming features found in Java 8 ( like the arrow Lambda operator), then you need at least the Java 8 JDK for compiling. Since the JDK supplies the compiler for your Java programs, the JDK you use determines what Java version you are able to code in. 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).

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.
