Overview of this book

Since its inception, Java has stormed the programming world. Its features and functionalities provide developers with the tools needed to write robust cross-platform applications. Java Fundamentals introduces you to these tools and functionalities that will enable you to create Java programs. The book begins with an introduction to the language, its philosophy, and evolution over time, until the latest release. You'll learn how the javac/java tools work and what Java packages are - the way a Java program is usually organized. Once you are comfortable with this, you'll be introduced to advanced concepts of the language, such as control flow keywords. You'll explore object-oriented programming and the part it plays in making Java what it is. In the concluding chapters, you'll get to grips with classes, typecasting, and interfaces, and understand the use of data structures, arrays, strings, handling exceptions, and creating generics. By the end of this book, you will have learned to write programs, automate tasks, and follow advanced courses on algorithms and data structures or explore more advanced Java courses.

Introduction


This is the last topic in our discussion on OOP. So far, we have already looked at classes and objects and how we can use classes as blueprints to create multiple objects. We saw how we can use methods to hold the logic of our classes and fields to hold the state. We've discussed how classes can inherit some properties from other classes to allow easy reusability of code.

We've also looked at polymorphism, or how a class can redefine the implementation of a method inherited from the superclass; and overloading, or how we can have more than one method using the same name, as long as they have different signatures. We've also discussed functions or methods.

We've looked at typecasting and interfaces in our previous lesson and how typecasting is a way for us to change an object from one type to another, as long as they are on the same hierarchy tree. We talked about upcasting and downcasting. Interfaces, on the other hand, are a way for us to define generic behaviors that our classes...
