JDK version history

Jdk1.5:

Released on December 31, 2004-ended on December 31, 2006

Jdk1.6

Released on December 31, 2006-ended on December 31, 2010

I was shocked by the fact that JDK was already used in the second half of 2010, but it was learned to be version 1.5. I knew the work, and I also used version 1.5, but it was all the basic functions of JDK, there are not many thread pools and annotations for 1.4 of NiO and 1.5. They are used only in original scenarios. They are used as programming models and have little in-depth understanding of them, today, I have read about the evolution of the version, and I know that the technology is developing fast. Some advanced concepts that have been used in development many years ago are also basic, or a few people are using it during development ,........ innovation capability still does not work ....... it is difficult to compare with overseas developers ....... sorry, computer research is not just as simple as programming models.
