Java manual download page. Get the latest version of the Java Runtime Environment (JRE) for Windows, Mac, Solaris, and Linux. Technical detail: I am using the Java 1.8.121 Java Development Kit JDK and Java 1.8.121 Java Runntime Enviroment JRE also i am using the Minecraft Bukkit 1.11.2 Library witch runns on Servers down to Minecraft 1.8.0!! For this Plugin i will allways use the Latest Bukkit Version to keep it up to date.!! Java Runtime Environment (JRE) is Java’s most basic virtual machine. It’s a required component to run any Java-based application or web applet. Java software allows you to run applications called 'applets' that are written in the Java programming language.

Installed Programs:appletviewer, extcheck, idlj, jar, jarsigner, java, javac, javadoc, javah, javap, java-rmi.cgi, jcmd, jconsole, jdb, jdeps, jhat, jinfo, jjs, jmap, jps, jrunscript, jsadebugd, jstack, jstat, jstatd, keytool, native2ascii, orbd, pack200, policytool, rmic, rmid, rmiregistry, schemagen, serialver, servertool, tnameserv, unpack200, wsgen, wsimport, and xjc

Installed Libraries:/opt/OpenJDK-1.8.0.121/lib/*, and /opt/OpenJDK-1.8.0.121/jre/lib/*

Short Descriptions

appletviewer	allows to run applets outside of a web browser.
extcheck	checks a specified jar file for title and version conflicts with any extensions installed in the OpenJDK software.
idlj	generates Java bindings from a given IDL file.
jar	combines multiple files into a single jar archive.
jarsigner	signs jar files and verifies the signatures and integrity of a signed jar file.
java	launches a Java application by starting a Java runtime environment, loading a specified class and invoking its main method.
javac	reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files.
javadoc	parses the declarations and documentation comments in a set of Java source files and produces a corresponding set of HTML pages describing the classes, interfaces, constructors, methods, and fields.
javah	generates C header and source files that are needed to implement native methods.
javap	disassembles a Java class file.
java-rmi.cgi	is the Java RMI client.
jcmd	is a utility to send diagnostic command requests to a running Java Virtual Machine.
jconsole	is a graphical console tool to monitor and manage both local and remote Java applications and virtual machines.
jdb	is a simple command-line debugger for Java classes.
jdeps	shows the package-level or class-level dependencies of Java class files.
jhat	parses a java heap dump file and allows viewing it in a web browser.
jinfo	prints Java configuration information for a given Java process, core file, or a remote debug server.
jjs	is a command-line tool used to invoke the Nashorn engine. It can be used to interpret one or several script files, or to run an interactive shell.
jmap	prints shared object memory maps or heap memory details of a given process, core file, or a remote debug server.
jps	lists the instrumented JVMs on the target system.
jrunscript	is a command line script shell.
jsadebugd	attaches to a Java process or core file and acts as a debug server.
jstack	prints Java stack traces of Java threads for a given Java process, core file, or a remote debug server.
jstat	displays performance statistics for an instrumented JVM.
jstatd	is an RMI server application that monitors for the creation and termination of instrumented JVMs.
keytool	is a key and certificate management utility.
native2ascii	converts files that contain non-supported character encoding into files containing Latin-1 or Unicode-encoded characters.
orbd	is used to enable clients to transparently locate and invoke persistent objects on servers in the CORBA environment.
pack200	is a Java application that transforms a jar file into a compressed pack200 file using the Java gzip compressor.
policytool	creates and manages a policy file graphically.
rmic	generates stub and skeleton class files for remote objects from the names of compiled Java classes that contain remote object implementations.
rmid	starts the activation system daemon.
rmiregistry	creates and starts a remote object registry on the specified port on the current host.
schemagen	is a Java XML binding schema generator.
serialver	returns the serialVersionUID for one or more classes in a form suitable for copying into an evolving class.
servertool	provides an ease-of-use interface for application programmers to register, unregister, startup and shutdown a server.
tnameserv	starts the Java IDL name server.
unpack200	is a native implementation that transforms a packed file produced by pack200 into a jar file.
wsgen	generates JAX-WS portable artifacts used in JAX-WS web services.
wsimport	generates JAX-WS portable artifacts.
xjc	is a Java XML binding compiler.

System Requirements for Installing the JDK on macOS

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

Any Intel-based computer running macOS.
Administrator privileges.
You cannot install Java for a single user. Installing the JDK on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK on macOS.

Determining the Default JDK Version on macOS

When starting a Java application through the command line, the system uses the default JDK.

There can be multiple JDKs installed on the macOS system.

You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 14 Interim 0, Update 0, and Patch 0, then you see a string that includes th
