博客展示了Java中类与接口的使用。定义了InterfaceFactory类，通过反射创建OutBoundDbConnection实例；同时定义了OutBoundDbConnection接口，包含多个Dbconnection方法。最后给出了调用示例，创建InterfaceFactory对象并调用其方法获取连接。

类中

public class InterfaceFactory {

OutBoundDbConnection outboundDbConnection = null;

public OutBoundDbConnection getOutboundDbConnection()
  throws
   InstantiationException,
   IllegalAccessException,
   ClassNotFoundException {
  outboundDbConnection =
   (OutBoundDbConnection) Class
    .forName("com.isoftstone.struts.biz.dao.ConnData")
    .newInstance();
  return outboundDbConnection;
}

}

接口

public interface OutBoundDbConnection {

public Connection Dbconnection(String dbdrivers, String dbname);
public Connection Dbconnection();
public Connection Dbconnection1();
}

调用

InterfaceFactory interfaceFactory = new InterfaceFactory();

con = interfaceFactory.getOutboundDbConnection().Dbconnection();
