There are 4 choices for the alternative java (providing /usr/bin/java).
If your system has multiple Java versions, then the command would list all Java versions like below. Use the alternatives command to set the default java version. # Oracle Java 16 # sudo update-alternatives -install /usr/bin/java java /usr/lib/jvm/jdk-16.*/bin/java 1 # Oracle Java 11 # sudo update-alternatives -install /usr/bin/java java /usr/lib/jvm/jdk-11.*/bin/java 2 # Oracle Java 8 # sudo update-alternatives -install /usr/bin/java java /usr/lib/jvm/jdk1.8.*/bin/java 3 Run update-alternatives commands to install Java on your system. jdk-11.0.12_linux-圆4_bin.deb # Oracle JAVA JDK 8 # sudo mkdir -p /usr/lib/jvm/ sudo tar -zxvf jdk-8u301-linux-圆4.tar.gz -C /usr/lib/jvm/ jdk-16.0.2_linux-圆4_bin.deb # Oracle JAVA JDK 11 # sudo apt install -y. # Oracle JAVA JDK 16 # sudo apt install -y. Install / Extract the downloaded Oracle Java package. # Oracle Java JDK 16 # wget -no-check-certificate -no-cookies -header "Cookie: oraclelicense=accept-securebackup-cookie" # Oracle Java JDK 11 # wget -no-check-certificate -no-cookies -header "Cookie: oraclelicense=accept-securebackup-cookie" # Oracle Java JDK 8 # wget -no-check-certificate -no-cookies -header "Cookie: oraclelicense=accept-securebackup-cookie" If you still want to use the command line, use the below command.
#HOW TO INSTALL OPENJDK 7 JDK IN RASPBERRY PI DOWNLOAD#
Then, download the Debian binary package for easy installation.ĭownload Oracle Java 11 LTS (v11.0.12) (Login Required)ĭownload Oracle Java 8 (v8u301) (Login Required) Go to the Oracle JDK page to download packages using the browser. You can either use the command line or browser to download Oracle Java. Instead, Oracle JDK now provides JRE as well. There is no separate JRE (Java Runtime Environment) anymore in Oracle Java. Install OpenJDK JRE # Default JRE # sudo apt install -y default-jre # Java JRE 11 # sudo apt install -y openjdk-11-jre
However, you can install Oracle Java 8.Install OpenJDK JDK # Default Java JDK # sudo apt install -y default-jdk # Java JDK 11 # sudo apt install -y openjdk-11-jdk OpenJDK v8 is not available in Debian 11. You can use the apt command to install OpenJDK. Installing OpenJDK in Debian is a pretty straightforward process. But, you can have only one default version.
You can have multiple versions of Java (OpenJDK and Oracle Java) on your system. Install OpenJDK or Oracle Java as per your requirement. There is no technical difference between OpenJDK and Oracle JDK. Oracle develops Oracle Java SE, whereas the OpenJDK is now developed by Oracle Corporation, OpenJDK and Java Community, Red Hat, IBM, Azul Systems, Apple Inc, and SAP SE.
