Overview

Class Central Tips

This is the second course in the Amazon Junior Software Developer Professional Certificate. In this course, you will explore advanced Object-Oriented Programming (OOP) concepts in Java, starting with an introduction to Interfaces and Abstract Classes. You'll learn how to effectively utilize interfaces for achieving multiple inheritance and how abstract classes play a crucial role in designing class hierarchies. Moving forward, you'll dive into Exception Handling, covering various types of exceptions in Java, along with best practices for handling them using try-catch-finally blocks. You'll also gain knowledge of File I/O operations, acquire skills in reading from and writing to files, understand different types of streams, and perform file operations efficiently. Finally, you'll explore Serialization and Deserialization techniques, enabling you to save and reconstruct object states, as well as use last run files for configuring current run states effectively. Overall, this course equips you with advanced Java programming skills essential for developing robust, efficient, and scalable applications. After completing this course, you’ll be able to: • Develop methods to organize and reuse code effectively. • Apply object-oriented programming concepts within the Java language to design modular and scalable code. • Handle errors and exceptions in Java to create robust applications.

Syllabus

Advanced OOP concepts

In this module, you'll explore advanced object-oriented programming (OOP) concepts, specifically interfaces and abstract classes in Java. You'll learn the importance of interfaces for code flexibility and how to implement them effectively, particularly in managing the challenges of multiple inheritance. Additionally, you'll understand the role of abstract classes in designing well-organized and extensible class hierarchies.

Defensive programming: Error handling

In this module, you will explore exception handling, focusing on mastering techniques to effectively manage errors in Java programs. You'll cover various aspects, including understanding the different types of exceptions in Java, such as checked and unchecked exceptions. You'll learn how to use try-catch-finally blocks to handle exceptions gracefully and ensure proper resource management. Additionally, the module will highlight best practices for exception handling in Java, equipping you with the skills to write robust and reliable code that gracefully handles unexpected situations.

File handling

In this module, you will explore file handling operations in Java, covering topics such as reading from and writing to files, understanding different types of streams including byte streams and character streams, and performing file I/O operations such as reading, writing, and appending data to files. Additionally, you'll explore the concepts of serialization and deserialization, learning how to serialize objects to save their state and deserialize them to reconstruct their state.

Final project and assessment: Programming with Java

This module focuses on applying the comprehensive knowledge of Java programming acquired from previous modules to a practical, real-world project. The challenge entails integrating various aspects of Java programming to enhance the zoo project you created in the previous course by employing file I/O operations and serialization. Through this module, you will demonstrate your ability to enhance your own software program.
