The JDK also comes with a complete Java Runtime Environment (JRE), usually called a private runtime, due to the fact that it is separated from the "regular" JRE and has extra contents. It consists of a Java virtual machine and all of the class libraries present in the production environment, as well as additional libraries only useful to ...
The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection algorithm used and any internal optimization of the Java virtual machine instructions (their translation into machine code) are not specified. The main reason for this omission is to not ...
java is the Java runtime launcher, a type of SDK Tool (A command-line tool, such as javac, javadoc, or apt)-classpath D:\myprogram sets the path to the packages used in the program (on Linux, -cp /home/user/myprogram) and; org.mypackage.HelloWorld is the name of the main class

The Java Runtime Environment (JRE) released by Oracle is a freely available software distribution containing a stand-alone JVM (HotSpot), the Java standard library (Java Class Library), a configuration tool, and—until its discontinuation in JDK 9—a browser plug-in
Note that Java EE runs on the standard Java SE JVM but that some vendors specialize in providing a modified JVM optimized for Java EE applications. Much Java development work takes place on Windows, Solaris, Linux, and FreeBSD, primarily with the Oracle JVMs. Note the further complication of different 32-bit/64-bit varieties.
Almost all of JCL is stored in a single Java archive file called "rt.jar" which is provided with JRE and JDK distributions. The Java Class Library (rt.jar) is located in the default bootstrap classpath [1] and does not have to appear in the classpath declared for the application. The runtime uses the bootstrap class loader to find the JCL.
JSR 277 later was put on hold and Project Jigsaw [2] was created to modularize the JDK. This JSR was superseded by JSR 376 (Java Platform Module System). Project Jigsaw was originally intended for Java 7 (2011) but was deferred to Java 8 (2014) as part of Plan B, [3] and again deferred to a Java 9 release in 2017. [4]
