13.32 loading and saving TodoItems part 2

The "loading and saving TodoItems part 2" Java module focuses on the implementation of a functionality that allows users to save and load their TodoItems. This module builds upon the previous module, which introduced the concept of saving and loading data using file input/output streams.

In this module, students will learn how to use serialization to save and load objects to and from files. They will explore the Serializable interface and its methods, as well as the ObjectOutputStream and ObjectInputStream classes. Students will also learn how to handle exceptions that may occur during the serialization process, such as the IOException and ClassNotFoundException.

The module will provide students with hands-on experience in creating a TodoItem class that implements the Serializable interface and writing methods to save and load TodoItems to and from a file. They will also learn how to test their implementation using JUnit tests.

By the end of the module, students will have a solid understanding of serialization and how it can be used to save and load objects in Java. They will be able to apply this knowledge to other projects and create more robust applications that can save and load data efficiently.
