Java is a popular programming language that runs on various devices and platforms. Java is a foundational technology for building many applications and web services, making it an essential skill for any programmer. We will discuss the difference between the Java Development Kit (JDK) and the Java Platform Standard Edition (Java SE).

What is the difference between Java SE and JDK?

The Java Development Kit (JDK) is a package of tools for developing Java applications.

It includes the JRE and everything you need to write, compile, and run Java programs (the compiler, interpreter, and tools). In addition, it includes documentation on how to use the APIs in your code.

The JDK also contains javadocs with documentation on what each class or method 

in the standard library does.

Java SE is a platform for developing and running Java applications.

Java SE is a platform for developing and running Java applications. It contains the JRE, the runtime environment needed to run a Java application, and the JDK, which contains tools needed for developing and maintaining your application. The JRE is dynamic and changes over time (e.g., new versions of it are released with each new release of the JDK).

All modern versions of Java are available as JDKs.

There are two different JDKs: the Standard Edition (SE) and Enterprise Edition (EE). SE is the standard version of Java that most developers use for writing web applications, desktop applications, and other software projects. If you want to create an application that runs on any operating system—Windows, Linux, or Mac OS X—you will need to download a version of Java SE for your operating system.

However, you need extra features such as clustering capabilities for large-scale deployments or support for advanced hardware like GPUs. In that case, consider using Java EE instead.

The JDK contains the JRE.

The JDK includes a reference implementation of the Java Virtual Machine. It is also meant to be a development kit for developing applications, applets, and components using the Java programming language. On the other hand, Java SE or Standard Edition has been designed for consumer electronic devices such as mobile phones and set-top boxes.

The JRE (Java Runtime Environment), part of the JDK package, provides runtime support for executing compiled Java code on end-user computers or servers (client systems). When you install Oracle’s JRE along with your application, only one version of the runtime environment is needed to execute your application on different platforms.

The JRE is static and does not change over time.

The JRE is the runtime environment, a subset of the JDK. The JRE contains only those components needed to run programs written in the Java programming language.

The JDK includes everything you need to write and compile Java programs but no applications or applets that can be run on your computer. You must install a JRE and a development kit (JDK) to develop applications.

If you want only an installation that can run Java-based applications (applets), use the JRE instead of installing both packages separately.

They’re both parts of a complete Java environment.

The JDK is a collection of tools, while JRE is the runtime environment.

The JDK contains everything you need to develop and compile Java code for any platform. It includes compilers and other development tools, such as javac (the compiler) and jar (for creating archives), and applications like JavaDoc that allow you to generate documentation from source code. It also comes with several command-line utilities, such as map, which can be used to look at memory usage by Java processes.

In contrast, the JRE is just one part of the complete Java environment: it contains everything needed to run compiled Java programs on your computer. Still, it does not include any development tools or utilities necessary to create new Java applications.

Conclusion

The JDK and JRE are both parts of a complete Java environment. The JDK contains the JRE and other tools for developing Java applications, while the JRE only implements the Java Runtime Environment (JRE). Developers can choose between these two options based on their needs—for example, the JDK may be more suitable if they need access to certain APIs not available through just using a standard JRE.
