  • Ubuntu has removed JDK 7 from the repository. Also, it is no longer supported for any further updates. So you better install jdk8. – Kulfy Jul 10 '18 at 08:19
  • If you still want it you can download from here http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html – Kulfy Jul 10 '18 at 08:20

    thanks for the answer, but I want to install openjdk, not Oracle jdk – duongtan Jul 10 '18 at 14:53
  • Why is this marked as duplicate if the suggested answer applies to a different version of Ubuntu? – mitchus Apr 20 '20 at 16:15

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
