I was wondering if anyone knows if it will be possible for me to install Java 8 on an EC2 instance. My application is packed as a fat jar with embedded jetty, so the Java 8 runtime alone should be sufficient.
I'm not too familiar with Linux, and I saw that they only had Java 7 support on the default AMI. Is there a simple command I can run to update to Java 8?

By default, the EC2 instance does not have Java installed. You can check it using the command in the EC2 console. Now, create a sub-directory named jvm inside /usr/lib/jvm. You can access this folder by accessing the basic file system using cd ..
Follow the steps below to install Java JDK11 on AWS EC2: Step 1: Create an AWS Elastic Cloud Compute Instance. Step 2: Start the EC2 instance that you have created in Step 1. Step 3: Connect to your EC2 Instance by clicking on Connect Button.
check Java current version
java -version install Java 1.8
sudo yum install java-1.8.0 change the Java version
sudo alternatives --config java 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.
