Install Java 8 on Debian

The following can be used to install Java 1.8 on Debian 10

From the following link;

https://adoptopenjdk.net/installation.html?variant=openjdk8&jvmVariant=hotspot#x64_linux-jdk

---

1) wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -

2) sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/

If the above fails;

2) - (optional) sudo apt-get install -y software-properties-common

3) sudo apt-get install adoptopenjdk-8-hotspot



both java installations (assuming the default was installed) can be found in /usr/lib/jvm

Also, mind update netbeans.conf (probably in /usr/local/netb*/etc/) to point to java 8 as opposed to (11 for example), assuming we're using NB8.2

Failure to do the above may not prevent NB from launching but may well prevent you from Creating a New Project
