In this guide, we will download the 64-bit installer: jdk-8u331-windows-圆4.exe.Īccept the license pop-up and click on the Download jdk-8u331-windows-圆4.exe button. Verify your windows bit version and click on the corresponding link: Look for the Java SE Development Kit 8u331 section. Head over to the Oracle Java SE 8 download page. Oracle’s OpenJDK (open source) – you can use this for free in any environment.Oracle’s JDK (commercial) – you can use this in development and testing for free, but if you use it in production you have to pay for it.Instead of having a single JDK build which you can use for free, they now have two different JDK builds: Note that Oracle has changed the license of their JDK. The official reference implementation is maintained by Oracle. To do this the JRE uses Java libraries and a Java Virtual Machine (JVM) that executes the compiled Java code.ĭifferent JDK implementations are available. The JDK also contains a Java Runtime Environment (JRE) that is able to run compiled Java code. Other tools include an archiver (jar) and a documentation generator (javadoc). One of these development tools is a compiler (javac) that converts Java source code (. It contains tools that allow you to develop and run your Java program. When you want to create a Java application you need a Java Development Kit (JDK).
JDK can work with any version of Java you want to use.Check following guides if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.7, JDK 1.9 or JDK 1.10.
Getting started is as easy as downloading and adding to your classpath. Create your programs using the best tools availableĮveryday programmers and professionals alike use these programs to create thousands of unique programs. While it might be easy to confuse the JDK with the JRE, the distinct element of the JDK is the package that is used to develop code, while JRE is primarily made to run Java code. JVM is the component that executes programs, JRE is the portion of Java that creates the JVM, and the JDK allows a developer to create Java programs. The three programs you’ll need to get started with Java programming work together in tandem to help you along. The two other technology packets you’ll need are the JVM (Java Virtual Machine) and the JRE (Java Runtime Environment). It’s one of the three core pieces of technology you’ll need to get started in your Java programming endeavors. At the heart of Java programming lies the Java Development Kit.
