Scroll down a tad look for the main table with the header of "Java Platform, Standard Edition". Click the JRE Download Button (JRE is the runtime component. JDK is the developer's kit). Select the appropriate download (all platforms and 32/64 bit downloads are listed) edited Aug 17, 2011 at 17:12. Metro Smurf.
They're very high quality and come in multiple variants for Windows ranging from zip files to MSI installers. Dead simple to install JDK 8, 11 or 15. But, after the installation when I tried checking the version using command java -version it's showing like regular JDK. This is because JAVA_HOME is pointing to your old JDK. You need to go to ...
In the worst case, for work around, just install 32 bit JDK, it should work fine in 64 bit OS. After all this, if you are successful in installing, please follow this link to configure JDK JDK STEP BY STEP
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode) And if you got: C:\Users\EeeMt>java 'java' is not recognized as an internal or external command, operable program or batch file. You should check your system environment variable. configure system environment variable. new variable "JAVA_HOME" add to "Parh"
This question is particularly relevant since Chrome still does not have a 64-bit version for Windows. In this case, you may end up having to install both versions: 64-bit for Java programs run in the OS, and 32-bit for web applets run in Chrome. _ –
Since Solaris has both a 32 and 64-bit J2SE implementation contained within the same installation of Java, you can specify either version. If neither -d32 nor -d64 is specified, the default is to run in a 32-bit environment. Other Java commands (javac, javadoc, etc.) will rarely need to be executed in a 64-bit environment.
Think of a DLL a custom Windows program that be called by other programs (including Java) running in Windows. Because a DLL is native, it can be either 32 or 64 bit. Java must be able to "speak" to the DLL using the right language, and therefore you must use either a 32 or 64 bit JVM. Bytecode is independent of the instruction width, but DLLs ...
If it is not Oracle's Java, you may not be able to tell. When I install Oracle Java 64-bit, the files go into C:\Program Files\Java, but when I install a 32-bit version, they default to C:\Program Files (x86)\Java instead. Of course, the person who installed Java could have overridden those defaults.
To use rJava in 64-bit R, you need Java for Windows x64. To build or check R packages with multi-arch (the default) you need to install both Java For Windows x64 as well as Java for Windows x86. On Win 64, the former installs in C:\Program files\Java\ and the latter in C:\Program Files (x86)\Java\ so they do not conflict.
If like me you do not have admin rights to install 64-bit Java, just open 32-bit R and it should work ok on your 64 bit PC as part of the problem seems to be the rJava library function calls embedded Java functions/routines, which may only have being designed for 32-bit interface with Excel/Windows and possibly too large a task at the time to change everything.
