Install Java on CentOS/Fedora
Installing Java on both CentOS and Fedora are quite similar, since they both supports YUM for their package management and installer tool.
Install OpenJDK 12 on Fedora 30 /CentOS 7
You can use yum search to search for the openjdk version you are planning to install.
$ yum search openjdk
In Fedora, you can search for java-latest-openjdk keyword and you should be able to find “java-latest-openjdk.x86_64 : OpenJDK Runtime Environment 12” if you are going to install 64-bit JDK or you can go for 32-bit JDK with “java-latest-openjdk.i686 : OpenJDK Runtime Environment 12”. Here is the command to install 64-bit on Fedora
$ yum install java-latest-openjdk.x86_64
YUM shows you a confirmation text with a transaction summary of the openjdk dependencies packages are being installed as pre-requisite packages for openjdk.

You can check the version of the java installed using java -version
$ java -version openjdk version "12.0.1" 2019-04-16 OpenJDK Runtime Environment 19.3 (build 12.0.1+12) OpenJDK 64-Bit Server VM 19.3 (build 12.0.1+12, mixed mode, sharing)
Install Java SE (Oracle JDK) 12 on Fedora 30 / CentOS 7
Installing Java SE or Oracle JDK on Fedora/CentOS is partially manual. That means you need to download the .rpm package manually using a downloader cli tool like wget:
$ wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/12.0.1+12/69cfe15208a647278a19ef0990eea691/jdk-12.0.1_linux-x64_bin.rpm"
Here is the log if the download is successful. Make sure the size of file download is more than 100MB. If the size of the file is around kilobytes that means you have messed up with Oracle License Agreement that you have passed as Header Cookie in your wget request.

Finally using following rpm command with -Uvh switch to ignore the verification of dependencies.
The trick is since you already installed openjdk using yum command, it has already installed the dependencies that are required for Java SE or Oracle JDK. I did not dig to find the Oracle JDK dependencies as pre-requisite for its installation, since I am not fan of non FOSS (Free Open Source Software). If something failed on running java or javac command complaining about a missing dependency, you need to google the error and find the solution.
However, you can install that .rpm local package.
$ sudo rpm -Uvh jdk-12.0.1_linux-x64_bin.rpm
You will get a warning because you have not provided a RPM key
warning: jdk-12.0.1_linux-x64_bin.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

Use jEnv to Switch JDKs
You can refer to Switch JDKs using jEnv page, if you have multiple JDKs installed on your machine, and you need to switch between them fast and without going and set $JAVE_HOME and $PATH environment variables
