Answer 1

As per November 2020

you can achieve this in 2 steps

1. Install the Java 11 using the yum

   yum install java-11-openjdk-devel

2. Get all the Java configurations available in your machine

   alternatives --config java

   Run the above command, select the version you want to set, I've set 1 here

   There are 2 programs which provide 'java'.
   Selection    Command
   
   -----------------------------------------------
      1           java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.8.10-0.el7_8.x86_64/bin/java)
   *+ 2           java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.262.b10-0.el7_8.x86_64/jre/bin/java)
   
   Enter to keep the current selection[+], or type selection number: 1
   

3. check java -version

   openjdk version "11.0.8" 2020-07-14 LTS
   OpenJDK Runtime Environment 18.9 (build 11.0.8+10-LTS)
   OpenJDK 64-Bit Server VM 18.9 (build 11.0.8+10-LTS, mixed mode, sharing)
   

The Java 11 is now set to use globally in the machine.
