I have jdk 8 on my ubuntu desktop. I need to install the latest jdk 9 for Java programming. What are the commands for Java programming and IDE such as Netbeans or Eclipse?



sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java9-installer

Update your environment variable after that

sudo nano /etc/environment

Add / Edit this line


Save and run

source /etc/environment

Test if environment variable was set


(Optional) For Linux Mint Users:

sudo apt install gsfonts-x11 oracle-java9-set-default

Update: Oracle Java 9 has reached end of life. Users of Java SE 9 should switch to Java SE 10. Source

To install Java 10, follow this.

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java10-installer

You can see which versions are available in your PPA's:

sudo apt-cache search java-sdk

If you want something else that this is suggest using SdkMan


After install see what it can give you by:

sdk list java
