Install Java 11

Download File

1. Create an Oracle account and sign in

2. Download Oracle JDK 11 .tar.gz archive. Make sure the Oracle JDK version you're downloading is the same as the oracle-java11-installer-local package version. E.g. the installer is currently version 11.0.3, so it can be used to install Oracle JDK 11.0.3.

3. Create a /var/cache/oracle-jdk11-installer-local/ folder, and copy the Oracle JDK 11 .tar.gz to this folder.


Install JDK

1. To add the PPA, open terminal either from app launcher or by pressing Ctrl+Alt+T on keyboard. When it opens, run command:

sudo add-apt-repository ppa:linuxuprising/java

2. Then run commands to install the script to start downloading and installing Java 11 on your Ubuntu:

sudo apt-get update
sudo apt-get install oracle-java11-installer-local

3. If you have installed multiple Java versions, install (or remove) oracle-java11-set-default package to set (or not set) Java 11 as default.

sudo apt-get install oracle-java11-set-default-local

Finally check Java version via

java -version
