Thinking Map learning Java programming Idea __ algorithm

It took 1 months to read the idea of Java programming. Then use Mindjet MindManager to do the reading notes, share with you ~

The reading notes of this mind map do not cover all the points of knowledge in the book, but they are clearer as a framework and as a way of reading.
There are a lot of code in the mind map that is not posted to the blog.
There is no summary of the 3rd chapter, the 22nd chapter, "Graphical user interface" in the mind map because it is used very little.
