How to pass this challenge?

Am I pasting the output incorrectly? Here is what I get and it's completely right: (Code version attached)

java version "9" Java(TM) SE Runtime Environment (build 9+178) Java HotSpot(TM) 64-Bit Server VM (build 9+178, mixed mode)

But then a bummer pops up saying "That output doesn't look correct. You sure you ran java -version?" I have no idea how else I have to paste it. I've tried it very differently many times.

java version "9"
Java(TM) SE Runtime Environment (build 9+178)
Java HotSpot(TM) 64-Bit Server VM (build 9+178, mixed mode)

Hi there,

I'm not sure what you're running that on but I thought the latest version of Java was 1.8.0_144? I've not done the update yet, so I'm at 1.8.0_141. For me, running java -version gives me:

java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode)

I don't think the compiler recognises Java "9".

Steve.

You must be on a beta release of Java. I'd suggest just copying my message above and progressing with the course!

Thank you Steve! What's with the version 9 then? Even if it is beta, I think there will be no significant difference with working with it I guess. Although when I run find /Library/Java/ it shows me that I have the 8th version of Java.

There will be differences but at our level we won't need to worry about them!

The path to the relevant bits of Java is usually C:\Program Files\Java (on a Windows machine).
