The foothold of this article is not a data mining-based algorithm or some detailed algorithm implementation. I have already written a lot of details about this in some blog posts, but at first we saw this pure technology blog, some formulas and some algorithms, which are hard to avoid. Therefore, in the early stage, it is necessary to provide overall conceptual guidance. It is a good thing for those who want to work hard in data mining. In fact, our confusion is that we do not know what it can d

For the results of the design, we always want to see highlights, quality, details, and so on. But the points of these considerations are mixed, making it difficult for designers to check each design for verification when performing design work. I want to share to everyone, for the product of different types of quality, it is to achieve the purpose is different, the end of the design is also different, only in the right position with the force, in order to shape an excellent design.At the same ti

multithreading, avoid the use of resources, occupy multiple objects. The relative disadvantage is to lock a section of the program, other procedures assume that the need to invoke the words must wait, reduce the speed, efficiency. It is possible to create a deadlock that causes the program to break. Summary:The previous understanding of the singleton pattern was only to know that it could be used to instantiate a Window object, and that only one object was instantiated. Now learned the J2SE th
