Install the OpenJDK package:

yum install java-[VERSION]-openjdk-devel

To install it to alternatives, run these commands:

sudo alternatives --install /usr/bin/java java usr/lib/jvm/java-[VERSION]-openjdk/bin/java 1000

sudo alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-[VERSION]-openjdk/bin/javac 1000

As root, run the alternatives command for java:
```
/usr/sbin/alternatives --config java
```
Select /usr/lib/jvm/jre-[VERSION]-openjdk/bin/java.
Then do the same for javac:
```
/usr/sbin/alternatives --config javac
```
Select /usr/lib/jvm/java-[VERSION]-openjdk/bin/javac.
