In concurrent programming, the use of containers is often encountered. But if a container is not thread-safe, then the process of inserting or deleting multiple threadsThere will be a variety of problems, is the problem of non-synchronization. So the JDK provides a thread-safe container that allows the container to be securely plugged in multi-threaded situations.Import and delete. Of course, there are two types of thread-safe

OpenStack is an excellent cloud operating system, and it is wise for developers, administrators, and operators to have the skills associated with them in their virtual toolkit. Efficient cloud requires an efficient database and can accept multiple databases. But what if you want IBM? DB2 for OpenStack, what should I do? OpenStack does not support DB2 by default.

ObjectiveThe context container is a representative of a Web project that primarily manages the servlet instances, where the servlet instances appear as wrapper. Now the question is how can we find the detailed servlet through the context container? Before you solve the problem.

Containers are an important part of the Java language learning. Mason my feeling is just beginning very difficult to learn, but so you know it, contact more, also "logical" to understand. Java's container classes are mainly derived from two interfaces:collection and Map.First, Collection vs collectionsFirst, Collection and collections are two different concepts. The reason why they are put together is to make a better comparison. collection is the roo

IL implements simple IOC containers and ilioc containers Now that I understand the knowledge between the IL interface and the dynamic class, why not experiment with the project? The first reaction is to think of the IOC container that is often said in the ordinary times.
