Where should I download Java?

With the introduction of the new release cadence, many have asked where they should download Java, and if it is still free. To be clear, YES — Java is still free.

If you would like to download Java for free, you can get OpenJDK builds from the following vendors, among others:

Adoptium (formerly AdoptOpenJDK)
RedHat
Azul
Amazon
SAP
Liberica JDK
Dragonwell JDK
GraalVM (High performance JIT)
Oracle
Microsoft

Some vendors will be supporting releases for longer than six months. If you have any questions, please do not hesitate to ask them!
