Crack your Java interview by preparing important topics and mastering key concepts in a guided and structured way in a short time.  Cracking a Java Interview is not easy, and one of the main reasons for that is Java is very vast. There are a lot of concepts and APIs to master to become a decent Java developer. 

Many people who are good at general topics like Data Structure and Algorithms, System Design, SQL, and Databases fail to crack the Java interview because they don't spend time learning the Core Java concepts and essential APIs and packages like Java Collection Framework, Multithreading, JVM Internals, JDBC, Design Patterns, and Object-Oriented Programming.

This book aims to fill that gap and introduce you to classical Java interview questions on these topics. By going through these questions and topics, you will not only expand your knowledge but also get ready for your Next Java interview. 

This book is for programmers preparing for Java interviews. This book contains frequently asked questions and their answer/explanations on essential Java topics. You can use this book to quickly revise all essential Java concepts before your interview, both telephonic and face-to-face, and you can also use this book to learn Core Java in depth. 

This book contains frequently asked Java questions from essential topics like

1. Object-Oriented Programming

2. Java Fundamentals

3. Java Collections

4. Java Multithreading

5. Garbage Collection

6. JDBC

7. Generics

8. Design Patterns

9. Telephonic Interview Questions 

These questions are a compilation of my best Java interview articles which millions of Java developers have read, and it is also my ten years of experience writing Java articles, tutorials, and interview questions. 

If you are preparing for Java interviews, then I highly recommend you to go through these questions before your telephonic or face-to-face interviews; you will not only gain confidence and knowledge to answer the question but also learn how to drive Java interviews in your favor. 

This is the most important tip I can give you as a Java developer.

Remember, your answers drive interviews, and these questions will show you how to drive an Interviewer to your strong areas. All the best for the Java interview, and if you have any questions or feedback, you can always contact me on Twitter javinpaul, or comment on my blogs Javarevisited and Java67

Java Interviews are notoriously tough, not because they ask impossible algorithmic questions like Google or Amazon. Still, because of the vast nature of Java API, Frameworks, and Libraries. ! It’s not enough for you to know Java and expect that you will be able to clear Java Interviews.

To pass the Java Interviews, you should also know essential Java frameworks like Spring, Spring Boot, and Hibernate. In my previous book, Grokking the Java Interview, I touched upon essential core Java topics like Collections, Multithreading, and Java Fundamentals. In this book, I have shared common Spring Framework questions from Job interviews.

Spring Framework is the most popular and almost standard framework for developing Java applications, both core java and java web application that runs on servers like Tomcat.

Like Java, Spring Framework is also very vast. Several sub-projects like Containers, Core Spring Concepts like IoC and Dependency Injection, Spring MVC, Spring Boot, Spring Data JPA, Testing, and miscellaneous Spring APIs.

This book contains frequently asked questions from essential Spring topics like

1. Container, Dependency, and IOC

2. Spring Bean Lifecycle

3. Aspect-Oriented Programming (AOP)

4. Spring MVC

5. Spring Boot Intro

6. Spring Boot Auto Configuration

7. Spring Boot Starter Dependency

8. Spring Boot Actuator

9. Spring Boot CLI

10. Spring Boot Testing

11. Spring Cloud Questions

12. Spring Data JPA

13. Spring Security

These questions are also a compilation of my best Spring Boot articles that millions of Java developers have read. It is also my 10 years of experience writing Java and Spring articles, tutorials, and interview questions.

If you are preparing for Java and Spring Boot interviews, then I highly recommend you to go through these Spring Boot and Spring questions before your telephonic or face-to-face interviews; you will not only gain confidence and knowledge to answer the question but also learn how to drive Java interview in your favor.

This book is also useful for Java developers preparing for the Spring Professional Certification Exam because I have tried to answer most of the questions from the Official Spring Certification Exam guide. This means you can use this as a review study guide for your spring certification preparation as well.

All the best for the Java interview, and if you have any questions or feedback, you can always contact me on Twitter, javinpaul, or comment on my blogs, Javarevisited and Java67.
