real fake, fake it for real.So what is the result of using and or not combining together? Example:What is the meaning of this phenomenon, just now I said, the logical operation is from the left to the right of the operation, first count not is not the true,true is true meaning, add a not is not true, that is flase, then add a not, and the fake made the real. So the result of not true is true. Well, now that it's out, it's not going to be the back of the operation. So the direct display of a tru
A scenario with Recyclerview nested Recyclerview is used.
The first interface of the shopping cart is Recyclerview, and each item contains a store. Use Recyclerview in the item to include multiple items in a store or shop.
Realize the idea:
Use an interface callback to callback the listener event for a second adapter product selection to the first adapter and then back to mainactivity in the first adapter.

See a lot of students permission to judge is to use string and then or split or intercept
In fact, to allow/disallow (True/false) This kind of permission, the logical operation is more appropriate
Statement: This article is aimed at getting started and for the mastery of the students, if they already understand that can be ignored
Perhaps the meaning of the expression is not very clear, please forgive me.

The Bayes theorem considers P (a| b) is the likelihood that a occurs when B occurs. In reality, event A is affected by multiple events and may also be affected by the last event a itself (feedback).

Let's say what is regression, for example, we have two types of data, each with 500 points, when we draw these points, there will be a line between the two sets of data, we draw this curve (because it is very likely non-linear), is regression. We use a lot of data to find this line, and to fit the
These days, take over a colleague's code, about the development of micro-letter interface, that a heap of if, see Brother egg pain, this problem is also a lot of beginners easy to make, so specially to write this refactoring.
Let's take a look at the problem with this code, if the code block logic in the if else inside is hard to change, making it reusable 0 and difficult to read. Of course, if there are only one or two, or 3, this is not a very good

From the perspective of gctexamination, the logic knowledge and Examination Form are limited and focused. Even though there are more than a dozen courses in the software designer examination, as long as you know how to strengthen understanding and use of important knowledge points and examination forms, the examination is easier to find a pass. However, whether it is a software designer or gcttest, if it is purely for the test, it will lose the meanin
The Business Logic layer (Business Logic Layer) is undoubtedly the part of the system architecture that embodies the core value. Its focus is mainly on the development of business rules, the implementation of business processes and other business requirements related to the system design, that is, it is related to the domain of the system to deal with the logic,
Introduction: Using the Rules engine can reduce the maintenance and scalability costs of applications by reducing the complexity of components that implement complex business logic. This updated article shows how to use the open source Drools rule engine to make Java™ applications more adaptable to change. The Drools project introduces a new local rule expression language and an Eclipse plug-in that makes Drools easier to use than ever before.
