When you get stuck with a certain topic in one book, the chances are strong that you will get a clear explanation somewhere else. Each chapter ends with exercises and puzzles: they will help you memorize the material.
Pros: engaging storytelling, great illustrations, and real-life explanations. Probably the best book to learn Java from scratch. Cons: sometimes the puzzles are a bit confusing. But due to the plain language, they explain the main terms simply without any confusions. You will learn the major things you need to start with Java coding, like how to install Java, compile code and complete different practical exercises after you finish the reading.
It is as easy as books for kids. Cons: nothing more than a plain introduction in Java. Java: Programming Basics for Absolute Beginners by Nathan Clark Another book for readers with a zero experience in coding will guide you step-by-step through the basics.
You will learn how to choose an IDE and write the first program. The book familiarizes you with Java Development Kit and Java Runtime Environment and gives the description for each part of the code in examples. It serves as a rather good preliminary environment before you delve into more serious subjects.
OOPS Concepts in Java with Examples
Pros: smooth intro to Java programming and its main features. But this book requires a little bit more understanding of programming comparing to the previous sources. It will deepen your understanding of Java origins and its relations to other programming languages.
It is profound research about the core concepts of Java which explains the code by line and guides you from the basic understanding of data types, classes and objects to more complex concepts like lambda expressions and functional interfaces.
The great part of this book is a self-test section at the end of each chapter.
Pros: a plain tone of voice, self-testing, full coverage of Java core. Cons: you need at least a small prior understanding of programming. It puts aside the playful tone and focuses on detailed explanations of Java core.
Each chapter is devoted to a certain subject, starting from introduction to the language and Java programming environment and moving to data structures, objects and classes and so on. Unlike many books for beginners, Core Java gives an explicit coverage of collections and generics, which is useful for real programming.
All in all, it is a great reference book.
Read it once and return to it anytime you need to refresh your knowledge. Pros: a full reference to Java Core and attention to collections and generics, profound explanations. Cons: some topics, like generics, are covered less diligent than others.
Like many others, it starts with an introduction to OOP. It is also a rather good reference book. Each chapter has the vocabulary and exercise sections to consolidate theory and master the skill of programming thinking.
It is more suitable for beginners than readers with even a small experience in coding. For starters, it is simple and kind of fun to read. Pros: a source for adjusting your way of coding, practice, basic concepts explained clearly. Cons: cannot be considered as the complete reference for core Java; the same level of complexity in all exercises. Cheers to that! Effective Java is written by Joshua Bloch This is not a book for a complete beginner but is must-read research for every Java developer.
If you want to understand the inner processes and get a clue of how and why they are arranged this way, this book serves the purposes well. It will teach you how to write the code and how to do it well. Pros: easy to read, covers best practices in programming, useful advice for improving your coding. Cons: requires an understanding of core concepts and at least a small experience in coding. It covers the Java 8 APIs, and clearly explains the basic concepts and beyond that.

Thinking in Java by Bruce Eckel This book offers you a rather refreshing approach to explaining Java fundamentals.
It has a focus on Java language design and behavior, and includes many detailed explanations. You will get the understanding of how each topic fits in with OOP. The basic subjects are fully covered on the first pages of the book. The larger part can help you to cover the new ground. It is one of those books, which you will return to even after years of studying and coding.
Although some of the examples are a bit outdated, this book is still a profound source for learners, because it actually teaches you to think like a Java programmer and encourages you to code. Pros: a thorough source, plenty of code samples and exercises, excellent explanation of OOP concepts in Java. Cons: might be too complicated for a beginner. The value of the ID is not visible to the external user. But, it is used internally by the JVM to identify each object uniquely.
For Example: Pen is an object. Its name is Reynolds, color is white etc. It is used to write, so writing is its behavior.
Object is an instance of a class. Class is a template or blueprint from which objects are created.
OOPS Concepts in Java with Examples
So object is the instance result of a class. Class :: Collection of objects is called class. It is a logical entity.
A class is a group of objects that has common properties. It is a template or blueprint from which objects are created.Ways to achieve Abstraction There are two ways to achieve abstraction in java 1.
Java OOPs Concepts
But improving your style is very important in your further work. The most primitive of all programming languages having sequentially flow of control.
Therefore, the college name will be defined as static. It is no more the fancy language of developers but it has now become the mainstream of any application development in the world.
If you are preparing for Java job interviews then you can also take a look at some of my favorite algorithm and data structures questions, it may help in your preparation. Enterprise Applications such as banking applications.
