java interview questions book

Hello, Java programmers If you are preparing for Java Programming and Developer interviews and looking for the best resources then you have come to the right place. I have been sharing Java interview questions for the last 10 years on my blog Javaevisited and it has helped millions of Java developers so far and counting.

In this article, I am going to share few more resources which you can take to better prepare for Java developer interviews.

Apart from blogs and articles, you should also take the help of my book (Grokking the Java Interview) and courses specially written for Java interviews. Though nothing can substitute actual job experience, cracking the coding interview is a little bit different beast.

Even if you have good experience you may struggle to crack the online coding tests which are becoming very challenging for Java developers of all levels of experience.

Similarly, if you are not going for the exact same profile job then you can expect a hell of a lot of questions from vast topics of Java domain, which you might not have heard before.

That’s why good planning and preparation are a must to crack any Java development interviews. It’s equally important for both beginners with no professional experience and seniors with years of Java development experience.

In a Java developer interview, you often get two kinds of questions, first for core Java development role where the focus is mostly on core Java concepts like multi-threading, concurrency, design patterns, OOP, error handling, collections, JVM internals, GC, and Java performance tuning. The second kind of Java interview is for Java EE or Java web development role where the focus is mostly on Java EE related technologies like JSP, Servlet, EJB, JDBC, and frameworks like Spring, Hibernate, Web services like REST And SOAP, and messaging technologies like JMS and MQ Servies. But, in both cases, you need to pass an online coding test and there will always be some questions on Data Structure and Algorithms, and Software Design which are very difficult for any programmers without practice. In this article, I have covered two types of books, the first type are specially written to help with programming interviews, covering a wide range of questions starting from object-oriented design, coding, Data Structure, and Algorithms, Computer Science, Networking, Database, SQL, XML, and problem-solving skills And, second, they are specially written to cover Java-related concepts like Java Concurrency, Java Collections, JVM, and other Java APIs. Once you are done with these books, you can take on any Java interview with confidence.

Java Interviews usually have two kinds of questions, one based upon the facts and concept of Java programming language and API and other sare typical programming questions, some based on data structure and algorithm, software designs, computer science basics. Some require you to develop logic and coding and others are related to object-oriented programming and design patterns.

If you are preparing for Core Java, or Java Web developer interviews formerly and popularly known as Java EE or Java Spring Developer interviews then you also need to ask some questions on popular frameworks like JSF, Spring MVC and Hibernate. In this list, I am going to share the 7 best books that will cover all the topics you need to prepare for Java Programming interviews, including an online coding test.

This is probably the most popular book for Java and Programming job interviews. It’s very similar to any coding interview preparation book, but it got more questions and also covers more topics, better explanations and covers things like how to negotiate a job offer. As the title suggests 189 programming questions and solutions, you will find all popular questions there like a program to find all pairs from the array whose sum is k or how to reverse String in Java, etc. Once you will do the exercise given in this book, you will feel a lot more confident going to the Java interview. If you are going for a senior Java developer role and if you want to improve on particular areas like System design, which is often the toughest then I suggest you check out Grokking the System Design Interview course on Educative, a new, text-based interview online learning platform. This course is prepared by people who have worked as hiring managers on tech companies like Google, Microsoft, Amazon, and Apple, and you are bound to learn a lot to tackle this most difficult topic for coding job interviews.

The Grokking the Java Interview books contain frequently asked Java questions from important 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

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

Yes, that’s my biggest secret of cracking the Java interview, you need to encourage the interviewer to ask questions from your strong areas so that you can demonstrate the depth of your knowledge.

This is another excellent book, particularly to prepare for questions from Java programming concepts and API. You will find everything you need to Crack any Java interviews in this book. It’s like the ultimate guide for Java programming interviews. The book is particularly useful for passing online coding tests which are now an integral part of any Java developer interviews. Gone are the days where you can get a Java developer job by just knowing Java concepts, now you also need to pass a coding test that is heavily based on algorithms and data structure. If Coding and Data Structure is your weak area then this book can really help you and if you need a bit more practical guidance then you can also combine this book with the Data Structures & Algorithms — Interview!! course on Udemy for instructor-led training. It will help you to pass the online coding test, the first hurdle of any software engineering interview.

I have referred to this book in the past, and nowadays, I prefer the first book in this more than this one, but it’s still a relevant book. If you connect to this book, then you will find it enjoyable as well.

The good thing about these books is that it’s full of diagrams which help to understand the concept quicker and better.

Sorry, there was a problem.
