This tutorial will guide you on how to install\u00a0Java 9 Standard Edition Development Kit<\/strong>\u00a0(JDK) in\u00a0Debian<\/strong>\u00a0and Ubuntu based Linux distributions using PPA and from sources.<\/p>\n

Installing Java 9 Using PPA<\/h4>\n

To install latest\u00a0Java 9<\/strong>\u00a0version, first add following\u00a0webupd8team\/java PPA<\/strong>\u00a0to your system and update the repository package database as shown.<\/p>\n

$ sudo add-apt-repository ppa:webupd8team\/java\r\n$ sudo apt-get update\r\n<\/pre>\n
Once PPA has been added and updated, now search for the packages with name\u00a0oracle-java9<\/strong>\u00a0as shown.<\/p>\n
$ apt-cache search oracle-java9\r\n<\/pre>\n
\n
\"Search<\/a><\/p>\n
Search Java Packages<\/p>\n<\/div>\n
The above output confirms that the\u00a0Java 9<\/strong>\u00a0is available to install using the following command.<\/p>\n
$ sudo apt-get install oracle-java9-installer\r\n<\/pre>\n
\n
\"Install<\/a><\/p>\n
Install Java 9 in Ubuntu<\/p>\n<\/div>\n
If you have more than one Java installed on your system, you can install\u00a0oracle-java9-set-default<\/strong>\u00a0package to set\u00a0Java 9<\/strong>\u00a0as default as shown.<\/p>\n
$ sudo apt-get install oracle-java9-set-default\r\n<\/pre>\n
Please note that the same\u00a0webupd8team\/java PPA<\/strong>\u00a0also offers older versions of Java packages like\u00a0Java 8<\/strong>\u00a0and\u00a0Java 7<\/strong>.<\/p>\n
Installing Java 9 from Sources<\/h4>\n
In order to install\u00a0Java 9 SE SDK<\/strong>\u00a0in your system, on a Desktop Linux machine, first open a browser and navigate to\u00a0Java SE official download<\/a>\u00a0page.<\/p>\n
Here, select\u00a0Java SE Development Kit 9<\/strong>, hit on\u00a0Downloads<\/strong>\u00a0link and check\u00a0Accept License Agreement<\/strong>\u00a0in order to start the download process of the latest version of the tarball package.<\/p>\n
Java offers no pre-compiled packages in the form of\u00a0.deb<\/code>\u00a0packages for\u00a0Debian<\/strong>\u00a0based Linux distributions, so we need to use the gzipped tarball file to perform the installation.<\/p>\n
If you install\u00a0Java<\/strong>\u00a0on a headless machine or in servers, download\u00a0Java 9 SE JDK<\/strong>\u00a0archive via\u00a0wget command line utility<\/a>, by issuing the below command.<\/p>\n
$ wget --no-cookies --no-check-certificate --header \"Cookie: oraclelicense=accept-securebackup-cookie\" http:\/\/download.oracle.com\/otn-pub\/java\/jdk\/9.0.4+11\/c2514751926b4512b076cc82f959763f\/jdk-9.0.4_linux-x64_bin.tar.gz \r\n<\/pre>\n
After the download completes, navigate to the directory where\u00a0Java<\/strong>\u00a0package has been downloaded and issue the below commands to start installing Java software.<\/p>\n
The commands executed below will decompress\u00a0Java<\/strong>\u00a0tarball archive directly into\u00a0\/opt<\/strong>\u00a0directory. Enter java extracted path from\u00a0\/opt<\/strong>\u00a0directory and issue\u00a0ls command<\/a>\u00a0to list the content of the directory. Java executable files are located in\u00a0bin<\/strong>\u00a0directory.<\/p>\n
$ sudo tar xfz jdk-9.0.4_linux-x64_bin.tar.gz -C \/opt\/\r\n$ cd \/opt\/jdk-9.0.4\/\r\n$ ls\r\n<\/pre>\n
\n
\"Java<\/a><\/p>\n
Java Executable Files<\/p>\n<\/div>\n
Next, insert\u00a0Java<\/strong>\u00a0environment variables and the executable files path into your system\u00a0$PATH<\/strong>\u00a0variable, by issuing the below commands that will create a new file named\u00a0java.sh<\/strong>\u00a0into system profile.<\/p>\n
This method ensures that Java environment variables and executables will be accessible system-wide.<\/p>\n
$ sudo echo 'export JAVA_HOME=\/opt\/jdk-9.0.4\/' | sudo tee \/etc\/profile.d\/java.sh\r\n$ sudo echo 'export PATH=$PATH:\/opt\/jdk-9.0.4\/bin' | sudo tee -a \/etc\/profile.d\/java.sh\r\n<\/pre>\n
\n
\"Set<\/a><\/p>\n
Set Java Environment Variables<\/p>\n<\/div>\n
Finally, log out and log in back again to apply the settings and issue the below command to verify\u00a0Java<\/strong>\u00a0installed version on your system.<\/p>\n
$ java --version\r\n<\/pre>\n
\n
\"Verify<\/a><\/p>\n
Verify Java Version<\/p>\n<\/div>\n
Congratulations! The latest version of\u00a0Java 9 SE SDK<\/strong>\u00a0is now installed in your Debian based Linux machine.<\/p>\n
