You can install only one version of JDK of the same feature release. General Notes About Installing the JDK on Linux Platforms from RPM Packages If this functionality of the JDK is required, you need to manually configure it by making sure either the /etc/.java/.systemPrefs or jdk-1.8-oracle- arch/.systemPrefs directory exists. Installing the JDK from archive files doesn't configure the backing store for the system node of Java Preferences API (the Java package). Ensure that you rename the old directory if it contains files that you would like to keep. If you install the software in a directory that contains a subdirectory named jdk-1.8-oracle- arch, the installer overwrites files of the same name in that directory. If you do not have the root access, either install the JDK in your home directory or a subdirectory for which you have write permissions. If you install JDK in a specific location such as /opt, you must log in with root credentials to gain the necessary permissions. Installing the JDK automatically creates a directory named /usr/lib/jvm/jdk-1.8-oracle- arch, where arch is either 圆4 (64-bit systems), aarch64 (64-bit ARM systems), or x86 (32-bit systems), depending on the architecture of your system.
