Java Development Kit (JDK) 8: How to Download and Install It

JDK 8 was a long-running standard for Java development, but Oracle no longer offers free public downloads of JDK 8 directly, and it's well past its active support window. Here's what that means in practice and how to get a working Java setup today.

Recommended: Use a Current LTS Release

Unless you have a specific reason to stick with JDK 8, Eclipse Temurin (Adoptium) provides free, open-source builds of OpenJDK, including current LTS versions such as 17 and 21, that are safe to download directly from the official site with no registration required. These are drop-in replacements for most modern Java projects and get security updates that JDK 8 no longer receives.

If You Specifically Need JDK 8

Some older projects, coursework, or legacy enterprise applications still require JDK 8 specifically. Oracle still provides it through its official archive: Oracle JDK 8 Archive Downloads. Adoptium also publishes OpenJDK 8 builds if you'd rather avoid Oracle's license terms. Avoid third-party mirror sites offering JDK installers, always download JDKs from Oracle or Adoptium directly, since unofficial mirrors are a common source of tampered installers.

Installing on Windows

Run the downloaded installer, accept the license terms, and note the install path, usually under Program Files\Java. Then set the JAVA_HOME environment variable to that path so your IDE and command line can find it: open System Properties, Environment Variables, and add a new system variable named JAVA_HOME pointing to the JDK folder, then add %JAVA_HOME%\bin to your PATH.

Verifying the Install

Open Command Prompt and run java -version and javac -version. Both should report the version you installed. If you see 'not recognized as an internal or external command,' your PATH variable wasn't set correctly, double-check the JAVA_HOME and PATH steps above.

JDK 8 vs. Newer LTS Versions

Later LTS releases (11, 17, 21) add language features like var, records, switch expressions, and better garbage collectors, along with continued security patches. If you're starting something new without a legacy constraint, a current LTS is the more future-proof choice.
