JAVA core technology Volume 1, generic example, java Core Technology example
For this Code, many netizens are full of questions. First of all, there are a lot of questions. If you don't write the Pair class, you can compile it.
The Pair class is on the first two pages of other code.
Here, the characteristics of generics are written. Several constructors and parameter changes explain the generics.

Use the latest and coolest Android development technology and Android Development Technology
First, the development tool certainly cannot use eclipse, and of course android studio. Of course, the api version must be 23 + to support cardview, RecyclerView, and percentage layout.
In addition, android support v7 and android support design are introduced, so that the interface effect will not be too bad, that i
development process. These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who don't understand when evaluating complexity. They don't understand how it's going to work in other ways, and why it's not in software development. So, the next time you hear someone say, "I think you can develop it in a few days," n

These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who do not understand the complexity of the assessment.
