Simply open System Preferences (“Apple > System Preferences”), and then click “Java” (you will see the Java icon). This one is the easiest option for most users that like using the traditional, visual approach to computing on macOS. There are two ways that I recommend checking your Java version, and there is one procedure that I like to use to check which JDK is currently in use on my MacBook Pro. In recent versions of Java for macOS, the default install location for some files has changed and the places to look to determine your Java version, or Java JDK (“Java Development Kit” technically, now Java SE Development Kit, which stands for “Java Platform, Standard Edition Development Kit” downloads here) version, have also changed accordingly. In these situations, and others, it is very important to be able to quickly find out your Java and JDK versions on Mac. dmg files) that install the software program in different ways depending on the operating system (macOS) and Java versions on your machine. When you are about to download new software on Mac, developers may have generated multiple app containers (. It's also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing.Java is a class-based, object-oriented programming language that is fast and powerful and runs many important computing programs and platforms. Installing this update will ensure that your Java applications continue to run as safely and efficiently as always.
The JRE is the Java Runtime Environment, it covers most end-users needs. Contains everything required to run Java applications on your system. It is a package of everything necessary to run a compiled Java program, including the Java Virtual Machine (JVM), the Java Class Library, the java command, and other infrastructure. However, it cannot be used to create new programs. The JDK is the Java Development Kit, the full-featured SDK for Java. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). It is capable of creating and compiling programs. Usually, if you only care about running Java programs on computer you will only install the JRE. On the other hand, if you are planning to do some Java programming, you need to install the JDK instead.
Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server.
