Java Collection framework and java Collection 1. Java Collection class overviewA. Origins of Collections A. We use arrays to process multiple identical data, but the array space cannot grow dynamically. It is troublesome to insert or delete elements. We use a set to solve this problem. B. Set features: the element type

Description: First introduced the Java Collection framework contains the interface and classes, and then summed up the collection framework of some basic knowledge and key points, and combined with examples for a simple analysis.1. OverviewAll collection classes are located under the Java.util package. Only objects can be saved in the collection (a reference vari

frameworks that can reduce the difficulty of Java development, such as Struts, Hibernate, and the Spring framework, They play an important role in many of today's Java projects. 　　 Why should we adopt a framework? A framework is made up of classes that formally provid

used to build a rest api. Of course, in some cases, developers may need to save user information. "For such use cases, you can use HTTP sessions," Espina explained. Jooby provides a set of In-memory HTTP sessions, but developers can also choose different backends, such as Redis, HazelCast, and MongoDB. This HTTP session is designed to be as concise as possible and requires developers to carefully consider whether to use it, because it only allows mat
