I think that only the weak will say, 'After working hard to find the programmer 30 "," 30-year-old programmer will switch after the. "
This time, rapid technological change technology is not false, but said, "programmer to a certain age on creativity and learning ability are difficult to keep up with the younger generation." It really is nonsense.
Why this article?
Designers of the Java language to help Java programmers to do so many things, it has advantages and disadvantages. It is advantageous to allow Java to learn, but there are disadvantages part equally clear. If you encounter an error other than grammatical level and application level in the application is running, it should be how to deal with? For example, memory overflow occurs online environment how to do? How do GC time is too long? IO did not respond for a long time how to do? Method throws an exception inexplicable how to do?
All this is not only to write a few if ... else ... Java programmers can be resolved, which requires a lot of experience, a lot of practice, a lot of research on the details of the underlying implementation of Java, and this is often the most difficult part of most Java programmers test, some people simply do not want to go deep research, others studied a little bit of research not go on.
In order to allow the urgent need to enhance friends, take some detours less, padded short board for a limited time, here to share some of my own collection of books to learn the technology, there is a need these books PDF friends can forward the article to focus on me, and private letters reply to [learn] to get free way to receive!
