Field Summary

static String	SYSTEM_TYPE_BSD The system-type for a BSD operating system (freeBSD, openBSD, etc.).
static String	SYSTEM_TYPE_LINUX The system-type for a distribution of Linux (android, ubuntu, kubuntu, debian, openSUSE, gentoo, fedora, mandriva, etc.).
static String	SYSTEM_TYPE_MAC_IOS The system-type for a variant of Apples operating system ("Mac OS", "Mac OS X" or any variant of "iOS").
static String	SYSTEM_TYPE_MAINFRAIME The system-type for operating systems dedicated for mainframe machines ([Open]VMS, z/OS, BS2000, OS/360, OS/390, etc.).
static String	SYSTEM_TYPE_OTHER The system-type for anything else that is not further classified.
static String	SYSTEM_TYPE_UNIX The system-type for Unix explicitly excluding Mac OS, BSD-systems and Linux.
static String	SYSTEM_TYPE_WINDOWS The system-type for a variant of Microsoft Windows (including mobile variants).

Method Summary

String	getSystemArchitecture() This method gets the architecture of the operating system running this java virtual machine.
String	getSystemName() This method gets the name of the operating system running this java virtual machine.
String	getSystemType() This method gets the type of the operating system running this java virtual machine.
String	getSystemVersion() This method gets the version of the operating system running this java virtual machine in lower-case.
boolean	isLimitedDevice() This method determines if the operating system running this java virtual machine is for mobile or embedded devices or maybe tablets but not for full-fledged PC or server machines.

Constant Field Values

SYSTEM_TYPE_MAC_IOS

static final String SYSTEM_TYPE_MAC_IOS

The system-type for a variant of Apples operating system ("Mac OS", "Mac OS X" or any variant of "iOS").

See Also:

Constant Field Values

SYSTEM_TYPE_LINUX

static final String SYSTEM_TYPE_LINUX

The system-type for a distribution of Linux (android, ubuntu, kubuntu, debian, openSUSE, gentoo, fedora, mandriva, etc.).

See Also:

Constant Field Values

SYSTEM_TYPE_UNIX

static final String SYSTEM_TYPE_UNIX

The system-type for Unix explicitly excluding Mac OS, BSD-systems and Linux. This means operating systems like "[Open]Solaris", "HP-UX", "AIX", "DG/UX", "IRIX" are considered of this type.

See Also:

Constant Field Values

SYSTEM_TYPE_BSD

static final String SYSTEM_TYPE_BSD

The system-type for a BSD operating system (freeBSD, openBSD, etc.).

See Also:

Constant Field Values

SYSTEM_TYPE_MAINFRAIME

static final String SYSTEM_TYPE_MAINFRAIME

The system-type for operating systems dedicated for mainframe machines ([Open]VMS, z/OS, BS2000, OS/360, OS/390, etc.). A mainframe is a (traditional) high-end server.

Constant Field Values

SYSTEM_TYPE_OTHER

static final String SYSTEM_TYPE_OTHER

The system-type for anything else that is not further classified. Please note that in new releases of this project, a new classification can be added and systems that have been in SYSTEM_TYPE_OTHER are then of a new type.

Method Detail

getSystemName

String getSystemName()

This method gets the name of the operating system running this java virtual machine. Here is an incomplete list of possible results:

• Windows 95
• Windows 98
• Windows NT
• Windows 2000
• Windows CE
• Windows Me
• Windows XP
• Windows Vista
• Windows 7
• Mac OS
• Mac OS X

• Digital Unix
• HP UX
• AIX
• Irix
• MPE/iX
• Netware 4.11
• OS/2
• OpenVMS
• NetWare
• OFS1
• OS/390

Returns:

the OS name.

See Also:

SystemUtil.PROPERTY_OS_NAME

getSystemArchitecture

String getSystemArchitecture()

This method gets the architecture of the operating system running this java virtual machine. Typical results are:

• x86
• x86_64
• i386
• i686
• ppc
• ppc64
• PowerPc
• arm
• armv41
• sparc
• mips
• alpha
• PA-RISC

Returns:

the OS name.

See Also:

SystemUtil.PROPERTY_OS_NAME

getSystemVersion

String getSystemVersion()

This method gets the version of the operating system running this java virtual machine in lower-case.

Returns:

the OS name.

See Also:

SystemUtil.PROPERTY_OS_VERSION

getSystemType

String getSystemType()

This method gets the type of the operating system running this java virtual machine. The type is not something directly provided by the JRE. It is defined by this API and is derived from the system-name to make things easier for you.

Returns:

the type of the operating system as one of the SYSTEM_TYPE_* constants defined in this interface.

See Also:

SYSTEM_TYPE_WINDOWS, SYSTEM_TYPE_MAC_IOS, SYSTEM_TYPE_LINUX, SYSTEM_TYPE_BSD, SYSTEM_TYPE_UNIX, SYSTEM_TYPE_OTHER

isLimitedDevice

boolean isLimitedDevice()

This method determines if the operating system running this java virtual machine is for mobile or embedded devices or maybe tablets but not for full-fledged PC or server machines. In such case you can assume that you are running on a mobile or embedded device. Please note that this is NOT a guarantee.

Returns:

true if operating system is for limited device, false otherwise.
