The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the Java TM platform. This section will instruct you on how to set the JAVA_HOME and PATH environment variables to help ensure that your Java applications will run without issue. The Java SE 17.0.1, 11.0.13, 8u311, and 7u321 update releases are now available. The JDK is a development environment for building applications using the Java programming language. If you have chosen to install the full OpenJDK development kit, check the version of the compiler as well: javac -versionĪs of the time of this publication, this command should return: javac 11.0.7 OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing) OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS) This is generally slower than running applications that have already been compiled into Java bytecode, and may not be suitable if you plan to execute applications many times.Ĭheck the version of the JRE to verify that it has been properly installed: java -versionĪs of the time of this publication, this command should return: openjdk version "11.0.7" LTS While you can run Java applications directly with the JRE, your applications will be compiled every time they are executed. Install the OpenJDK 11 development kit, which includes OpenJRE 11: sudo apt-get install openjdk-11-jdkĪlternatively, if you simply want to run Java applications that you have already downloaded, you can choose to only install OpenJRE 11: sudo apt-get install openjdk-11-jre This guide will use sudo commands wherever possible, which should be run by a limited, non-root user on your Linode.Įnsure your system is up-to-date: sudo apt-get update & sudo apt-get upgrade Before You Beginįamiliarize yourself with our Getting Started guide and complete the steps for connecting to your Linode with SSH and setting your Linode’s hostname and timezone.Ĭomplete the sections of our guide on Securing Your Server to create a standard user account, harden SSH access and remove unnecessary network services. For this reason, OpenJDK 11 is the recommended version for developing production applications. While there are many available versions of OpenJDK, version 11 is the latest Long-Term-Support (LTS) release as of the time of this guide’s publication. OpenJDK and Java SE are equivalent JDKs that include a Java runtime environment (JRE) and tools for developing and compiling Java applications. OpenJDK is the free and open-source implementation of the Oracle Java Standard Edition (Java SE) Development Kit. For a description of the XDK directory structure, see About Installing XDK. This guide will show you how to install the Open Java Development Kit (OpenJDK) 11 on Ubuntu 18.04. Software written in Java can be compiled and run on any system, making Java a versatile platform that can be used to create anything from software to basic web applications. We should note that before this long-running project, there were JDK Release Projects that released one feature and were then discontinued.Java is one of the world’s most popular programming languages. JDK 20 binaries are free to use in production and free to redistribute, at no cost, under the Oracle No-Fee Terms and. And, just like for Oracle, the JDK Project will also deliver new feature releases every six months. Initially, it was based only on the JDK 7, but since Java 10, the open-source reference implementation of the Java SE platform is the responsibility of the JDK Project. We should emphasize that OpenJDK is an official reference implementation of a Java Standard Edition since version SE 7. Note: the versions in italics are no longer supported. Let's take a look at the Java SE history: Oracle strongly recommends using the term JDK to refer to the Java SE (Standard Edition) Development Kit (there are also Enterprise Edition and Micro Edition platforms). It's thus named because it contains more tools than the standalone JRE, as well as the other components needed for developing Java applications. It contains a complete Java Runtime Environment, a so-called private runtime. JDK (Java Development Kit) is a software development environment used in Java platform programming.
