Copies of past Debian packages are available at http://snapshot.debian.org/
You can search there for openjdk-8. The last available version is 8u322-b06-1~deb9u1, logged at http://snapshot.debian.org/package/openjdk-8/8u322-b06-1%7Edeb9u1/ You can download the binary packages (.deb) for your architecture and install with sudo dpkg -i *.deb.
Whether it works or not depends on the library versions that it was built against. 8u312-b07-1 (and other older versions) is also available.
Alternatively you can access the Debian tracking page for the package at https://tracker.debian.org/pkg/openjdk-8. openjdk-8 is still listed there as available for unstable (as version 8u312-b07-1). If you click on the links for the binary packages, they will lead you to download links for the deb packages.
snapshot.debian.org is arguably simpler for ad-hoc downloading since it has the deb files in one place (the debian package repository finds them in http://ftp.us.debian.org/debian/pool/main/o/openjdk-8/ or its mirror sites)
snapshot.debian.org also suggests instructions for configuring sources.list. But if the package is not likely to be updated often then it might be simpler to just download the deb files manually.
Answer from Rizzer on Stack ExchangeI recently upgraded my Debian version to the shiny new Debian 12, and I'm currently facing a small hiccup while trying to install OpenJDK-11. I'm aware that the apt install default-jdk command usually does the trick, but in this case, it installs version 17 of OpenJDK. Unfortunately, I specifically need JDK 11 for my project.
I successfully used apt install default-jdk in Debian 11 without any issues, so I'm wondering if there have been any changes in Debian 12 that require a different approach for installing OpenJDK-11. I'd greatly appreciate it if anyone could kindly guide me through the correct steps to install OpenJDK-11 on Debian 12.
Thank you in advance for your time and assistance!

Will Minecraft Java edition be reprogrammed for Java 11?
Minecraft comes with a private JRE on Windows, which means its security problems should typically not be as much of a concern for the operating system. Of course having to use a system JRE is a problem on other operating systems. As someone who considers switching to Linux myself before Win7 support runs out, I sure hope Mojang will address that problem soon, and not just Soon™.

Since Oracle changed Java licensing, Bellsoft (not affiliated) has done a great job at providing openJDK installers. They just work, and you can choose between:
- JDK / JRE
- Java 8 / 11 / 17 / 19
- With or without JavaFX
- Windows / Debian / Redhat / Alpine / Solaris / macOs installer
You'll surely find the correct installer at https://bell-sw.com/pages/downloads/#/java-8-lts.
You can install multiple Java versions if you wish. If you need to juggle between versions, you might be interested in this answer.
