concrete class

Write code to construct instances of any concrete class including normal top level classes and nested classes .

However, the subclass leaves the concrete class as is and does not attempt to instantiate the superclass.

As you can see in Figure 1, there is a service endpoint implementation (concrete) class and a service endpoint interface definition.

ScriptEngineManager is probably the only concrete class in the scripting package you'll use regularly; most of the rest are interfaces.

All you've done here is take the same signature you used for the method in the actual concrete class.

"Table per Concrete Class" is good for an OLTP system with high concurrency, complex queries and few shared columns.

Creates and initializes an instance of a concrete class derived from.

Every concrete class that implements the interface must supply the implementation details for theses members.

However, when no concrete class is specified, Hibernate needs to perform an SQL JOIN, since it doesn't know which table to go through.

First, much of the work done by a concrete class is specified in the docstrings of methods.

A class that is not a MustInherit class, one that can be instantiated, is called a concrete class.

Create a mock object class as a subclass of the concrete class.

For DI to work, you must have an interface whose concrete class you can inject into the consumer of the behavior you desire.

The generated delegation class is a concrete class instead of an abstract class.

Figure 7 presents the persistence model when each concrete class is mapped to a data entity.

What if the code we have uses a concrete class in its implementation?

The Abstract Server class here is closed for modification, and the concrete class implementations here are open for extension.

Instead of accepting an ICollaborator interface, it now accepts a concrete class implementation (the Collaborator class).

The instance variables were declared as part of the bean implementation, which was a concrete class.

The class can be either an interface or a concrete class.

The value object in Listing 2 looks almost identical to our remote interface, but it's actually a concrete class.

However, you must map the fields for each concrete class.
