Method

booleanis64BitJavaOnMac()
True if this JVM is running 64 bit Java on a Mac. 
return isMac() && System.getProperty("os.arch").equals("x86_64");
booleanis64BitJre()
is Bit Jre 
String prop = System.getProperty("sun.arch.data.model");
return prop != null && prop.contains("64");
booleanis64bitJVM()
isbit JVM 
String os = System.getProperty("sun.arch.data.model");
return os != null && os.equals("64");
booleanis64BitJVM()
Returns true if the current Java VM runs with a 64 bit architecture. 
return getJVMArchitectureName().contains("64");
booleanis64BitJVM()
Takes an educated guess as to whether 64 bits are supported by the JVM. 
if (!IS_64_BITNESS_KNOWN) {
    String arch = System.getProperty("os.arch");
    String sunModel = System.getProperty("sun.arch.data.model");
    IS_64_BIT_JVM = "amd64".equals(arch) || "x86_64".equals(arch) || "ppc64".equals(arch)
            || "64".equals(sunModel);
    IS_64_BITNESS_KNOWN = true;
return IS_64_BIT_JVM;
