Program Files is the directory name of a standard folder in Microsoft Windows operating systems in which applications that are not part of the operating system are conventionally installed. Typically, each application installed under the 'Program Files' directory will have a subdirectory for its application-specific resources.
While a 32-bit signed integer may be used to hold a 16-bit unsigned value with relative ease, a 32-bit unsigned value would require a 64-bit signed integer. Additionally, a 64-bit unsigned value cannot be stored using any integer type in Java because no type larger than 64 bits exists in the Java language.
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 ...
on Windows, the directory structure has a Windows syntax, and each file path must be separated by a semicolon (";"). This does not apply when the Classpath is defined in manifest files , where each file path must be separated by a space (" "), regardless of the operating system.
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 ...
32-bit architecture: All programs (both 16-bit and 32-bit) are installed in this folder. 64-bit architecture: 64-bit programs are installed in this folder. \Program Files (x86) Appears on 64-bit editions of Windows. 32-bit and 16-bit programs are by default installed in this folder, even though 16-bit programs do not run on 64-bit Windows.

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 ...
The SysWOW64 folder located in the Windows folder on the OS drive contains several applications to support 32-bit applications (e.g. cmd.exe, odbcad32.exe, to register ODBC connections for 32-bit applications). 16-bit legacy applications for MS-DOS and early versions of Windows are usually incompatible with 64-bit versions of Windows Vista, 7 ...
