The Java SE Development Kit, usually called the JDK, is the official toolkit from Oracle for building Java applications. It bundles the compiler, the runtime and the command line tools developers rely on every day. It suits students learning Java, professionals building server or desktop software, and anyone whose tools require a JDK on their Mac.

Key Features

• javac compiler that turns Java source code into runnable programs
• Java runtime for launching applications and development tools
• Debugging and monitoring tools such as jdb and jconsole
• jshell for testing small pieces of code interactively
• Full class libraries covering networking, files, security and interfaces

How to Download

1. Use the download button on this page to get the Mac installer.
2. Download from the official site if you want the current JDK builds and license terms from Oracle.
3. Pick the installer for your chip, Apple silicon or Intel, run it, then check the version by typing java version in Terminal.

System Requirements

Download the build that matches your Mac chip, since Oracle publishes separate installers for Apple silicon and Intel machines. Check your chip and macOS version under About This Mac before you choose a file.

FAQs

What is the difference between the JDK and the JRE?

The JDK includes everything needed to write and compile Java code, plus a runtime for running it. A plain runtime alone cannot compile new programs.

Is JDK 27 free to use?

Oracle offers JDK 27 under its No Fee Terms and Conditions, which allow production use at no cost. Always read the current terms on the Oracle site.

Can I keep more than one JDK version installed?

Yes. Macs commonly hold several JDK versions side by side, and development tools let you choose which one a project uses.
