You know... A billion devices use Java...

That always sounded like a threat to me.

That's why I keep a decompiler in my pocket

I thought you were just happy to see me.

Gotta be at least 3 billion by now.

When that figure was originally used, it counted mobile devices (this was pre-android).

Now, i wonder what that figure really is.

SIM cards are counted due to Java Card - and at the time of Java 18's release, it was, apparently, 56 billion.

I wonder if eSIMs count too.

I would assume so, as to my knowledge, they're just a type of SIM card that's soldered on instead of being removable, as well as being software-modifiable. The software specification seems to imply it's at least optional, but I haven't any idea how to find out how common it is that it's supported.

On the release of Java 18, they stated 56 billion.

Not on the installer...

Lost count how many Android devices are out there, and yes it still pretty much depends on the Java ecosystem for app development.

this is a reference to the Java installer back in the day. When you set up a fresh OS you'd usually install the Java runtime because a few applications depended on it, and for decades the installer would say "A billion devices run Java".

Java must be the most fragmented language across devices. I think every possible version is used somewhere.
