dynamic - determine os architecture and bitness in java -


i want able dynamically determine os, architecture, , bit-ness in java application.

for example, application know when on solaris 32-bit sparc machine or when on x86 machine.

i know system property returns arch of jvm, there find out real os arch , bit-ness?

the simplest way byte order use byteorder.nativeorder();

the os in system properties.

to determine if jvm 64-bit use following taken ehcache.

private static final boolean is64bit = is64bit0();  public static boolean is64bit() {     return is64bit; }  private static boolean is64bit0() {     string systemprop;     systemprop = system.getproperty("com.ibm.vm.bitmode");     if (systemprop != null) {         return systemprop.equals("64");     }     systemprop = system.getproperty("sun.arch.data.model");     if (systemprop != null) {         return systemprop.equals("64");     }     systemprop = system.getproperty("java.vm.version");     return systemprop != null && systemprop.contains("_64"); }
