Java is one of the most popular and widely used programming languages in the world. It is a versatile and powerful language that can create applications for various platforms, such as PC, laptop, tablet, web, and mobile. Learning Java can be a rewarding and challenging experience for anyone who wants to develop their programming skills and create solutions for today’s problems.

However, learning Java can also be daunting and confusing for beginners and experienced programmers alike. There are many concepts, features, and syntaxes that need to be understood and mastered. There are also many books and resources available for learning Java, but not all of them are clear, concise, and user-friendly.

This is where Let Us Java by Yashavant Kanetkar comes in handy. This book is a comprehensive guide to learn Java programming from the basics to the advanced topics. It is written in a simple and easy narration style that does not assume any programming background. It covers all the concepts of core Java with several examples and self-explanatory analogies. It also provides exercises and projects at the end of each chapter to test and reinforce your learning.

In this article, we will review Let Us Java by Yashavant Kanetkar and see what it has to offer for anyone who wants to learn Java programming. We will also compare it with other Java books and see how it stands out from the crowd.

What is Let Us Java by Yashavant Kanetkar?

Let Us Java by Yashavant Kanetkar is a book that teaches Java programming from scratch. It is written by Yashavant Kanetkar, a renowned author and speaker in the IT field who has written several books on C, C++, Java, Python, Data Structures, .NET, IoT, etc. He has also created Quest Video Courses on these topics that have helped millions of students and professionals around the world.

Let Us Java by Yashavant Kanetkar is divided into 22 chapters that cover all the aspects of Java programming. The book starts with an overview of Java and its features, followed by getting started with Java development environment and tools. Then it introduces the data types and control instructions of Java, such as variables, constants, operators, expressions, statements, loops, etc.

The book then moves on to the object-oriented programming paradigm of Java, which is the core of the language. It explains the concepts of classes and objects, constructors and destructors, methods and parameters, access specifiers and modifiers, static and final keywords, etc. It also shows how to use arrays and strings to store and manipulate data in Java.

The book then covers the topics of inheritance and polymorphism in Java, which are the mechanisms of reusing and extending existing code. It demonstrates how to create subclasses and superclasses, override methods and constructors, use abstract classes and interfaces, implement multiple inheritance using interfaces, etc.

The book then deals with the topics of exception handling and effective input/output in Java, which are essential for creating robust and user-friendly applications. It shows how to handle errors and exceptions using try-catch-finally blocks, throw and throws keywords, custom exceptions, etc. It also shows how to perform input/output operations using streams, readers, writers, files, directories, etc.

The book then explores the topics of multithreading and synchronization in Java, which are the techniques of executing multiple tasks concurrently and coordinating them safely. It explains how to create threads using Thread class and Runnable interface, control thread lifecycle using start(), join(), sleep(), interrupt(), etc., synchronize threads using synchronized keyword, wait(), notify(), etc., use thread pools and executors to manage threads efficiently.

The book then introduces the topics of generics and collection classes in Java,
which are the features that enable writing generic and reusable code that can work with different types of data. It shows how to create generic classes,
methods,
and interfaces using type parameters,
type arguments,
type bounds,
etc.,
use generic collections such as ArrayList,
LinkedList,
HashSet,
HashMap,
etc.,
use iterators,
comparators,
and comparables to traverse,
sort,
and compare collections.

The book then covers the topic of user interfaces in Java,
which are the components that allow creating graphical user interfaces (GUI) for applications. It shows how to use Swing framework to create GUI components such as windows,
buttons,
labels,
text fields,
menus,
dialogs,
etc.,
use layout managers to arrange components on containers,
use event listeners to handle user actions on components.

The book then concludes with the topic of database connectivity using JDBC (Java Database Connectivity),
which is the API that allows connecting to various databases from Java applications. It shows how to load drivers,
establish connections,
execute queries,
retrieve results,
update data,
handle transactions,
etc.,
using JDBC classes such as DriverManager,
Connection,
Statement,
ResultSet,
PreparedStatement,
etc.
