Question

How do you determine 32 or 64 bit architecture of Windows using Java?

Answer 1

You can use the os.arch property in system properties to find out.

Properties pr = System.getProperties();
System.out.println(pr.getProperty("os.arch"));

If you are on 32 bit, it should show i386 or something
