JavaLand Session: How is Java/JVM built?
Mr Webber developer and Ms Janet Java developer are both developers who are interested in broadening their know-how of the Java platform. Mr Webber developer shares with Ms Janet Java developer conservations about Javaland, vJUG, Nighthacking and Adopt OpenJDK – a preview of their conversation.
Mr Webber developer: Look Janet you always wanted to build you own JDK and now you can!
Ms Janet Java developer: Are you referring to the OpenJDK session at Javaland? I have signed up for it already. And you can do as well, even though you will be overseas in another time zone, the virtual Meetup is occurring at 2:45PM UK time and here’s some help foryour timezone calculation, refer to this. But don’t forget to tune in to the session at http://virtualJUG.com/#live
Mr Webber developer: So tell me more about OpenJDK as it sounds like you know more about it than me?
Ms Janet Java developer: starting with Java 7, OpenJDK is the Reference Implementation (RI) of Java. We will be shown its components, language composition and how you can build it with 3 or 4 simple commands, all of which isn’t common knowledge to mainstream Java developers.
Mr Webber developer: But I’m a practical person and would like to do it myself rather than just see a presentation, will that be covered too ?
Ms Janet Java developer: Of course you can either code along or watch how you can build your own JDK. Just follow the instructions in the Adopt OpenJDK Getting Started Kit (GSK) before the sessionto get set up and you can follow along with Mani and Daniel through the session.
Mr Webber developer: I’m thrilled about this and want to know more, I have questions coming from all directions.
Ms Janet Java developer: I will say you should refer to the GSK before signing on, on the day, it has all your questions answered –Adopt OpenJDK Getting Started Kit.
Mr Webber developer: Can I write my own GUI programs, games and graphics programs in Java?
Ms Janet Java developer: Of course, we can, Stephen Chin will be there, who is an OpenJFX expert.
Mr Webber developer: I’m sold , I just want to be there as soon as possible! But what if I’m late or miss it out totally.
Ms Janet Java developer: me too, looking forward to it. If you miss it, it’s not the end of the world you can always watch the video on the vJUG / Nighthacking sites and also refer to the Adopt OpenJDK Getting Started Kit (GSK) documentation above to try out all the practical steps on your own. And there is also an amazing mailing list, twitter handle, and newsletter you can join and follow – checkout the document, it’s all in there.
