The new path takes effect in each new command window you open after setting the PATH variable.Oracle's Java Runtime Environment (JRE) for 64-bit Windows PCs contains the Java Virtual Machine, software libraries, components, and plug-ins that tons of programs, media, and Web sites need to display advanced multimedia content and animation. If you are not sure where to add the JDK path, append it. Those following the first instance are ignored. You should only have one bin directory for a JDK in the path at a time. Microsoft Windows looks for programs in the PATH directories in order, from left to right. The PATH environment variable is a series of directories separated by semicolons ( ) and is not case-sensitive. The following is a typical value for the PATH variable:Ĭ:\WINDOWS\system32 C:\WINDOWS C:\Program Files\Java\jdk1.8.0\bin Set the PATH variable as follows on Microsoft Windows:Ĭlick Start, then Control Panel, then System.Ĭlick Advanced, then Environment Variables.Īdd the location of the bin folder of the JDK installation to the PATH variable in System Variables.
Typically, this full path looks something like C:\Program Files\Java\jdk1.8.0\bin. To set the PATH variable permanently, add the full path of the jdk1.8.0\bin directory to the PATH variable. It is useful to set the PATH variable permanently so it will persist after rebooting. If you do not set the PATH variable, you need to specify the full path to the executable file every time you run it, such as:Ĭ:\> "C:\Program Files\Java\jdk1.8.0\bin\javac" M圜lass.java If you want to install the JavaFX SDK (version 2.0.2) with JDK 7u1 or earlier, see for more information. Installers for JDK 7u2 to 7u5 install the JDK first, then start the JavaFX SDK installer, which installs JavaFX SDK in the default directory C:\Program Files\Oracle\JavaFX 2.0 SDK or C:\Program Files (x86)\Oracle\JavaFX 2.0 SDK on 64-bit operating systems. Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory.
When finished with the installation, you can delete the downloaded file to recover disk space. Then, follow the instructions the installer provides. If you downloaded either file instead of running it directly from the web site, double-click the installer's icon.
The file jdk-8 version -windows-圆4.exe is the JDK installer for 64-bit systems. The file jdk-8 version -windows-i586-i.exe is the JDK installer for 32-bit systems.
You must have administrative permissions in order to install the JDK on Microsoft Windows.
