Object-oriented Programming in Java
The document source “Object-oriented Programming in Java” delves into the fundamental concepts and principles of object-oriented programming using Java as the primary language. It explores topics such as classes, objects, inheritance, polymorphism, and encapsulation, essential for building robust and scalable software applications. The content likely covers how to create and manipulate objects, establish relationships between classes, and leverage inheritance to promote code reusability. Additionally, it may touch upon the benefits of encapsulation in maintaining code integrity and the flexibility of polymorphism in enhancing code flexibility and extensibility.
Using Inheritance and Polymorphism
In this chapter, the use of inheritance and polymorphism to build a useful data structure is discussed. It covers abstract classes, variations of classes, and the concept of class hierarchies formed b...

Software Testing
We know that a clean compile does not imply that a program will work correctly. We can detect errors in our code as we interact with the executing program. The process of exercising code to reveal err...
