This tutorial will guide you on how to install Oracle Java 12<\/a> on Debian 10.<\/p>\n\n\n\n

Installing Oracle Java 12 on Debian 10<\/h2>\n\n\n\n

To install the official Oracle Java on Debian 10, you need to add the PPA repository. But before that, ensure that your system packages are up-to-date.<\/p>\n\n\n\n

sudo apt update
sudo apt upgrade<\/code><\/pre>\n\n\n\n
Add Linux Uprising Java PPA Repository<\/h3>\n\n\n\n
To install Java 12 on Debian 10, you need to add the linux uprising java PPA repository as shown below;<\/p>\n\n\n\n
echo \"deb http:\/\/ppa.launchpad.net\/linuxuprising\/java\/ubuntu bionic main\" | sudo tee \/etc\/apt\/sources.list.d\/linuxuprising-java.list
sudo apt install dirmngr
sudo apt-key adv --keyserver hkp:\/\/keyserver.ubuntu.com:80 --recv-keys 73C3DB2A<\/code><\/pre>\n\n\n\n
Installing Oracle Java 12 on Debian<\/h3>\n\n\n\n
Once you have the Linux Uprising repositories to install Java 12, proceed to do the installations. <\/p>\n\n\n\n
sudo apt update
sudo apt install oracle-java12-installer<\/code><\/pre>\n\n\n\n
Verify Java Installation<\/h3>\n\n\n\n
Once the installation is done, run the command below to verify the installed Java version.<\/p>\n\n\n\n
java --version
 java 12.0.1 2019-04-16
 Java(TM) SE Runtime Environment (build 12.0.1+12)
 Java HotSpot(TM) 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing)<\/code><\/pre>\n\n\n\n
If you need to set Oracle Java 12 as the default Java version, install the following package if not already installed.<\/p>\n\n\n\n
sudo apt install oracle-java12-set-default<\/code><\/pre>\n\n\n\n
Define JAVA_HOME Environment Variable<\/h4>\n\n\n\n
If you have multiple versions of Java installed and want to set Java 12 as the default, you need to set Java 12 home environment variable. Before that, you need to find the Java 12 install location by running the command below;<\/p>\n\n\n\n
sudo update-alternatives --config java
 There is 1 choice for the alternative java (providing \/usr\/bin\/java).
   Selection    Path                                  Priority   Status
 0            \/usr\/lib\/jvm\/java-12-oracle\/bin\/java   1091      auto mode
 1            \/usr\/lib\/jvm\/java-12-oracle\/bin\/java   1091      manual mode 
 Press  to keep the current choice[*], or type selection number:<\/code><\/pre>\n\n\n\n
Now that we got the Java 12 install location, press Ctrl+c and open the \/etc\/environment<\/strong> configuration file where you can set Java home environment variable as shown below.<\/p>\n\n\n\n
vim \/etc\/environment<\/code><\/pre>\n\n\n\n
JAVA_HOME=\"\/usr\/lib\/jvm\/java-12-oracle\"<\/code><\/pre>\n\n\n\n
Next, source the \/etc\/environment<\/strong> file to load the environment variables.<\/p>\n\n\n\n
source \/etc\/environment<\/code><\/pre>\n\n\n\n
To confirm the Java home environment variable setting, run the command below;<\/p>\n\n\n\n
echo $JAVA_HOME
\/usr\/lib\/jvm\/java-12-oracle<\/code><\/pre>\n\n\n\n
