How can a Java program get its own process ID?

Question

How do I get the id of my Java process?

I know there are several platform-dependent hacks, but I would prefer a more generic solution.

Answer 1

public static long getPID() {
    String processName = java.lang.management.ManagementFactory.getRuntimeMXBean().getName();
    if (processName != null && processName.length() > 0) {
        try {
            return Long.parseLong(processName.split("@")[0]);
        }
        catch (Exception e) {
            return 0;
        }
    }

    return 0;
}
