Note: The PPA given here is not from Ubuntu or Oracle, instead of some third party or developer hence will not recommend for production systems. Well, if you don’t need this version of JAVA anymore then we can remove it using a simple command: sudo apt purge jdk-17 In the future, if you want to set some other version to be the default one then just change the folder path to Java binary as shown in the above commandįinally, to confirm the Oracle’s Java 17 is there run the given syntax: java -version Otherwise, run the given command: sudo update-alternatives -set java /usr/lib/jvm/ jdk-17/bin/ java If you don’t want to set Oracle Java 17 as your system-wide default Java then you can skip this step. Set default Java on Ubuntu 20.04/22.04 (optional) sudo update-alternatives -install "/usr/bin/java" "java" "/usr/lib/jvm/ jdk-17/bin/java" 1Ĥ. Inform system about new Oracle Java installationĪs we have installed it manually, let the system know that we recently have added a new version of java at some particular directory or path. Libx11-6 libx11-data libxau6 libxcb1 libxdmcp6 libxext6 libxi6 libxrender1 libxtst6 x11-commonģ. The following additional packages will be installed:Īlsa-topology-conf alsa-ucm-conf libasound2 libasound2-data libbsd0 libc6-i386 libc6-x32 libfreetype6 libpng16-16 Note, selecting 'jdk-17' instead of './jdk-17_linux-圆4_bin.deb' That’s is the reason why most of the Linux distributions provide OpenJDK through its default main repository.
#Ubuntu 20 install openjdk 11 license#
Whereas OpenJDK has the GNU General Public License (GNU GPL), it is an open-source version of Oracle Java with the same capabilities but free for all without any restriction. However, since Java 17, Oracle has made it free to use for all users. Hence, it is free for personal and development purposes but there are some restrictions for business and commercial or production usage, which means if someone wants to use any of them for business purposes they need to obtain a commercial license. Oracle JDK 11, Oracle JDK Java 8, and Oracle JRE with Java Web Start in Java 8 have been licensed under the OTN License Agreement for Java SE. But for those who don’t know exactly the difference between Oracle Java and OpenJDK, let’s talk a little bit about that.

What is the key difference between Oracle Jave and OpenJDK?
Hence, here we will know the steps to set up the same using the command terminal.
