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

In the previous lessons, you learned about various data structures in Java, such as lists, sets, and maps. You also learned about how to iterate on the many data structures, compare objects in many different ways; and sort these collections in an efficient way.

In this lesson, you will learn the implementation details of advanced data structures such as linked lists and binary search trees. As we progress, you'll also learn about a powerful concept called enumerations and explore how to use them effectively instead of constants. At the end of the lesson, you will gain an understanding of the magic and mystery behind equals() and hashCode().
