2, An abstract class allows you to create instances directly, but an interface does not allow you to create instances directly.

3, Implementation of methods of an abstract class is provided by derived classes, but implementation of methods of an interface cannot be provided by derived classes.

4, An abstract class contains attributes and methods that can be public, private, or protected, but an interface consists of only methods.

He currently needs to create a module to facilitate the issue of orders received and update the details of books sold in a database. However, before implementing this functionality in the code, Sam needs to graphically represent the interaction among various objects, such as Order and book database, in the form of messages ordered in a sequence of time. He created a diagram as shown in the exhibit. Click the Exhibit button to view the exhibit.

Identify the error in the diagram, if any."

1, The arrow labeled as "Transaction complete" should be actually labeled as destroyed.

60 Consider a scenario of an inventory management system. Whenever an inventory item is ordered, the inventory manager issues the requested items and simultaneously updates the database to keep a track of the total number of inventory items that are currently present. Recently, an enhanced version of a particular inventory item has been introduced in the market, which the inventory manager wants to keep in the store. However, the inventory store has a limited capacity. Therefore, un

til the old version of such inventory items are not sold out, the new enhanced version cannot be introduced in the store. You need to graphically represent this scenario by using a state machine diagram. Which feature of state machine will you use in this case to represent such a scenario?
