### Option 2: Install Java SE Development Kit 14 on CentOS 8/7 & Fedora 31-29

If you choose to go with [Java SE Development Kit 1](https://www.oracle.com/java/technologies/javase-jdk14-downloads.html)[4](https://www.oracle.com/java/technologies/javase-jdk14-downloads.html), download RPM package for CentOS / RHEL / Fedora system using the command below.

```

Then install the RPM package using the *yum* or *rpm* command.
