I have installed OpenJDK 1.7 on Ubuntu 18.04

Step 1. Install OpenJDK 1.7

sudo dpkg -i https://packages.debian.org/sid/libjpeg62-turbo
sudo dpkg -i https://packages.debian.org/experimental/openjdk-7-jre-headless
sudo dpkg -i https://packages.debian.org/experimental/openjdk-7-jre
sudo dpkg -i https://packages.debian.org/experimental/openjdk-7-jdk

Step 2. Switch to OpenJDK 1.7

export PATH=/usr/lib/jvm/java-7-openjdk-amd64/bin:$PATH

Note: If you want to use javac command instead of openjdk 1.7, use below command

sudo update-alternatives --config java
