Windows 8/7/Vista/XP/2000 Note: Downloading and installing of Java will only work in Desktop mode on Windows 8. If you are using the Start screen, you will have to switch it to Desktop screen to run Java. Windows Server 2008/2003; Intel and 100% compatible processors are supported; Pentium 166 MHz or faster processor with at least 64 MB of ...
A Java program running on a Windows Vista desktop (supported by Java 8, but not officially by later versions, such as Java 11) desktop computer. Current Java is supported on 64-bit Windows 10 (and Server 2016) and later, 64-bit macOS 13.x and later, and 64-bit Linux (e.g. Oracle Enterprise Linux).
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. The primary reference Java VM implementation is HotSpot, produced by Oracle Corporation and many other big and medium-sized companies (e.g. IBM, Redhat, Microsoft ...
Consequently, you can install a 32-bit or 64-bit JVM on a 64-bit operating system. The primary advantage of running Java in a 64-bit environment is the larger address space. This allows for a much larger Java heap size and an increased maximum number of Java Threads, which is needed for certain kinds of large applications; however there is a ...
The full JRE is 12 MB, a typical Swing application only needs to download 4 MB to start. The remaining parts are then downloaded in the background. [28] Graphics performance on Windows improved by extensively using Direct3D by default, [29] and use shaders on graphics processing unit (GPU) to accelerate complex Java 2D operations. [30]
AutoPatcher currently exists for Windows 2000, XP, Vista, 7, 8, 10 and some server equivalents (Windows 2003 and 2008). For some years it did not provide support for Windows 7 or older systems, nor for some 64 bit operating systems; updates are now possible for some of these in the 2014 version of Autopatcher.
In the RTM release of Windows Vista, files encrypted using the Encrypting File System (EFS) were not archived by the operating system's backup application; [106] this feature was reinstated in Service Pack 1. [107] Windows Vista Backup does not have all the features and command line parameters supported by NTBackup. [108]
JRE (originally from Sun, now from Oracle) features two virtual machines, one called Client and the other Server. The Client version is tuned for quick loading. It makes use of interpretation. The Server version loads more slowly, putting more effort into producing highly optimized JIT compilations to yield higher performance. Both VMs compile ...
