[SOLVED] Java 8 On debian 10

Hello, does anyone know how to downgrade to Java 8 on Debian 10? I want to play on older server software (for ex: 1.8.9, 1.7.10 etc)

Can anyone just guide me on how to install Java 8 and remove Java 11? Because I seem to have 0 luck.

nvm. Got it working with a frankenDebian method, @ me if you wanna know
