HOW WE TELL PROGRAMMATICALLY IF I'M RUNNING IN 64-BIT JVM OR 32-BIT JVM

Anonymous User 1927 11-Aug-2015

How can I tell if the JVM my application runs in is 32 bit or 64-bit? Specifically, what function or preference do I access to detect this within the program?

java javac

Sun has a Java System property to determine the bitness of the JVM: 32 or 64:

sun.arch.data.model=32 // 32 bit JVM
sun.arch.data.model=64 // 64 bit JVM

You can use

System.getProperty("sun.arch.data.model")

to determine if its 32/64 from the program.
