I tried installing opendjk-7 in the way that was suggested here, but I get this error:

W: The repository 'http://ppa.launchpad.net/openjdk-r/ppa/ubuntu yakkety Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/openjdk-r/ppa/ubuntu/dists/yakkety/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

There is no pagckage for Ubuntu 16.10 (Yakkety). Check openjdk-r/ppa/ubuntu/dists/ . Try to install openjdk9 instead

sudo apt-get update
sudo apt-get install openjdk-9-jdk
