If you are using the NetBeans Platform then you should add a dependency with the Utilities module (very useful):

Then you just say

Utilities.isMac() or Utilities.isUnix() or Utilities.isWindows().

In case you want to do it more precisely you can

switch( Utilities.getOperatingSystem() )
{
  case Utilities.OS_AIX: 
  case Utilities.OS_FREEBSD:
  case Utilities.OS_HP:
  case Utilities.OS_IRIX:
  case Utilities.OS_LINUX:
  case Utilities.OS_MAC:
  case Utilities.OS_OPENBSD:
  case Utilities.OS_OS2:
  case Utilities.OS_SOLARIS:
  case Utilities.OS_SUNOS:
  case Utilities.OS_TRU64:
  case Utilities.OS_WIN95:
  case Utilities.OS_WIN98:
  case Utilities.OS_WIN2000:

(Well, and all the rest, this is getting too long for an answer, I'm afraid, see the link above for more OSes).

thank u so much, this method is very nice to detect the OS. – Jay Apr 04 '12 at 05:52 — Jay, Apr 04 '12 at 05:52

Through:

String osName = System.getProperty("os.name").toLowerCase();

You get Os name and you able to compare with your os.For example:

boolean isMacOs = osName.startsWith("mac os x"); 
if (isMacOs) 
{
  // do mac-specific things here
}

System.getProperty("os.name"); should return the OS name.
