Oracle java for linux

The following are the system requirements for installing the JDK and the JRE on macOS:

Java

Linux Java Home

  • Any Intel-based computer running macOS.

  • Administrator privileges.

    You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.

  • When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.

    To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

  • When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.

    To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

    Note:

    Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To do this, you must install the JDK.

Under Oracle Java, only a single version of the JRE can be installed at a time. See Installing the JRE on macOS. To access the Java Control Panel, in the System Preferences panel, click the Java icon. If you don’t see the Java icon in the System Preferences, in the Other section, then you do not have an Oracle.

Many Linux distributions (such as Ubuntu 18.04 or 20.04) include OpenJDK 11 by default, so you can skip this step. Otherwise, use your Linux distribution’s package manager (see the first FAQ) to install OpenJDK 11. For example, here are the commands for Ubuntu 16.04.
