One of the functions of Java Preferences was to set the current version of the JRE. 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. JRE is the Java Runtime Environment (used to run any.jar file 'Java software'). The JDK contains a JRE inside it. On Windows when you update Java, it updates the JRE automatically. On Mac you do not have a JRE separated you have it, but inside the JDK, so when you update Java it will update your JRE which is inside your JDK; it doesn't install.
The following steps show you how to install a non-notarized JDK or JRE. Note: These steps use the JDK 8u231 macOS installer as an example. These steps apply equally to all other JDK and JRE releases. Installing the JDK Using a.dmg File. Double-click on the.dmg file to begin the installation.

Cloneable
This class provides the functionality of a 'Message Authentication Code' (MAC) algorithm.A MAC provides a way to check the integrity of information transmitted over or stored in an unreliable medium, based on a secret key. Typically, message authentication codes are used between two parties that share a secret key in order to validate information transmitted between these parties.
A MAC mechanism that is based on cryptographic hash functions is referred to as HMAC. HMAC can be used with any cryptographic hash function, e.g., MD5 or SHA-1, in combination with a secret shared key. HMAC is specified in RFC 2104.
Every implementation of the Java platform is required to support the following standard
