performance of the hash table.In fact, the Hashcode method defined by the object class does return different integers for different objects. (This is typically done by converting the object's internal address to an integer, but the JAVATM programming language does not require this implementation technique.) When the Equals method is overridden, it is often necessary to override the Hashcode method to maintain the general contract of the Hashcode method, which declares that the equality object m

In my experience as a developer, senior developer, architect, I have encountered good, poor, and even ugly enterprise-class Java projects. When I ask myself what makes a project successful and another failure, I find it hard to get a perfect answer, as if it's hard to define all the software projects with success. The Java EE project is no exception

?Which one of spring and Java EE is more friendly to developers?I think so far, many developers should be able to recognize that the success of a technology is not entirely dependent on their own strengths and weaknesses, but also depends on the developer's usage rate. The important thing to know is that "not every software developer is a star developer, there are many middle-level developers." In order for

1. Jndi namespaces
Obviously, the prerequisite for applying access to resources is that the required resources must first be found through Jndi naming, and the Jndi naming must conform to a uniform naming convention. To differentiate the scope of Jndi naming, the naming and directory service divides Jndi-named environment contexts into several namespaces, adding resources and their jndi names to namespaces in the form of "name/object", thereby enabling Jndi publishing of resources
