1.1. What is this

1.1.1. This is the first LJC collaborative mindmap to break down the language

1.1.2. Its a mindmap http://en.wikipedia.org/wiki/Mind_map

1.1.3. Barry's original post: I’m not sure if it will be as effective as I hope, but my gut feeling is that it will help non-techies and people that don’t use Java to understand how things fit together in the language so that the can better understand technical conversations. I also feel it could have potential for junior developers to form an idea how everything fits together. I also feel personally that it may actually also help developers of all levels to see where their skills lie and potentially where they need to develop further. Especially as one of the most popular rejections for interview is that the candidate didn’t know what they knew and what they didn’t know. I also feel that it could help provide the spine of a technology portfolio of a CV.


1.2.1. How should we break Java down into smaller chunks?- Here's a start... Where do these terms fit into the Javasphere? (Please put them into the map somewhere) OOAD i18n Questions Language, platform or APIS? All of the above Please add notes and questions in red through the map - Barry

1.2.2. If you would like to take part and edit it yourself then let me know and I'll send you an invitation - [email protected] Feel free to add / remove / edit / group / ungroup / connect any part of this map

1.3. Etiquette of this map

1.3.1. Feel free to add / remove / edit / group / ungroup any part of this map Add notes. AKAs are helpful.

1.4. Aims of this map

1.4.1. To find the most 'elegant' way to break the language down So that it can be read by technical and non technical people alike
