Figure 6.2. A Bridge structure moves the abstract operations that an abstraction relies on
into a separate interface.
It can be challenging to see how the classes in a JDBC application align with the B
RIDGE
structure that Figure 6.2 shows. The questions to answer are: Which classes are abstractions?
Which classes are "implementations"?
Consider the
JDBCAdapter
class that Sun Microsystems packages in the JDK as
a demonstration of how to display data from a database table. This class implements
the
TableModel
interface as shown in Figure 6.3.
