Description
This course provides a comprehensive look at Java inheritance, including access modifiers and overriding methods. Students are introduced to abstract classes, and will learn how to read and write to files, use regular expressions for parsing text, and how to leverage complex data structures like collections and maps.
Additionally, this course offers strategies for catching errors and debugging code, including an overview of Eclipse’s debugging tool.
Knowledge
- Examine the concept of inheritance in object-oriented programming and learn how to extend classes and override methods in a subclass.
- Analyze and fix different parts of a Java program using Eclipse's interactive debugger.
- Explore different methods for opening, reading, and writing to external files, and deal with errors and exceptions.
- Examine advanced techniques for storing and manipulating data in collections, and parse text using regular expressions (or regex).
