This makes it very easy for developers to use JDK tools including the Java compiler and the Java Shell. When the installer configures the Java PATH environment variable, all of the utilities that are part of the JDK can be invoked by name in a DOS prompt or in PowerShell. Java setup and install options for Windows Install optionĪny custom folder without a space or non-text character Instead, I recommended that the Java install directory be changed to something like: Where to install Java on Windows?īy default, Java installs into a subdirectory of C:\Program Files. The space between the words Program and Files can sometimes cause errors in scripts, which is why I recommend against installing Java in this folder. 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 developers, and such as the internationalization libraries and the IDL libraries.When you setup Java on Windows, change the installation folder and choose to set JAVA_HOME. The JDK also comes with a complete Java Runtime Environment, usually called a private runtime.
This tool also helps manage JAR files, javadoc - the documentation generator, which automatically generates documentation from source code comments, jdb - the debugger, jps - the process status tool, which displays process information for current Java processes, javap - the class file disassembler, and so many other components. JDK has as its primary components a collection of programming tools, including javac, jar, and the archiver, which packages related class libraries into a single JAR file. Java Development Kit contains the software and tools that you need to compile, debug, and run applets and applications that you've written using the Java programming language.
