Important notice regarding Oracle Java 11 and newer: the Oracle JDK license has changed
starting April 16, 2019. The new license permits certain uses, such as personal use and
development use, at no cost -- but other uses authorized under prior Oracle JDK licenses
may no longer be available.

sudo apt install --no-install--recommends oracle-java13-installer

sudo update-alternatives --config java
You can do this for other Java commands, such as the compiler (javac):
sudo update-alternatives --config javac
sudo update-alternatives --get-selections | grep ^java

sudo apt install openjdk-8-jdk
