Sharing my simple working approach

Downloading the JDK

curl -LO https://corretto.aws/downloads/latest/amazon-corretto-11-x64-linux-jdk.tar.gz

note: check the ec2 instance's platform ie., x64, aarch64, x86, aarch32 etc.,because the wrong platform jdk installation will leads to /bin/java: /bin/java: cannot execute binary file

Extracting the JDK to /usr/java/

sudo tar -xvzf amazon-corretto-11-x64-linux-jdk.tar.gz -C /usr/java/

Run the below single line command to change the soft link for java files in (/usr/bin) directory

cd /usr/java/amazon-corretto-*-linux-x64/bin
for i in java javac jfr; do path=$(find `pwd`/$i -type f); echo $path; sudo alternatives --install /usr/bin/i $path 20000 ; sudo update-alternatives --config $i ; done

after the above command execution, there will be a command prompt that will ask you to choose the selection number which represents the file residing path and we should choose the number which refers to path /usr/java/amazon-corretto-*-linux-x64/bin/

The amazon-corretto jdk version may vary based on the timeline that you download. Currently the java version is 11.0.12.7.1

That's it execute java -version, you can see the java version as

openjdk version "11.0.12" 2021-07-20 LTS
OpenJDK Runtime Environment Corretto-11.0.12.7.1 (build 11.0.12+7-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.12.7.1 (build 11.0.12+7-LTS, mixed mode)

Java 8 may not be available out-of-the-box on the AMI that you are looking for. However, you can always install it once the instance is created.

e.g. Check this post which explains how to install java 8 on Ubuntu OR check this post which explains how to install Java 8 on RHEL/Fedora/CentOS.
