  • 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.
