Top 5 Books to Learn Groovy for Java Developers in 2025 - Best Of Lot, Must Read

Groovy is a programming language that is specially created for Java developers with a view to being a fast-paced, scripting companion to Java. It aims to increase the productivity of Java developers by simplifying Java code and removing unnecessary boilerplate. Groovy not only present a succinct and easy to read syntax but also provide a much more elegant and convenient API than Java for common stuff. For example, a Groovy file can do in 50 lines what a Java source code does in 500 lines. You can declare an array as [] and map as [: ] which really makes code full of data without much syntax. Because of this property, Groovy is heavily used in unit testing of Java application. Some popular unit testing frameworks like Spock is also built on Groovy.

10 Tips to Improve Programming Skill and become a better Programmer

Many Java developers ask me how to become a better programmer? How do I improve my programming skills? Or I am good at Java but not so good at problem-solving ability etc. This is a reality, today's era is full of language experts than real programmers. It's easy to understand keywords, methods, and API of the Java programming language. Still, at the same time, it's challenging to solve practical problems, design reusable, and robust software, and get the best of data structure and algorithm. I have often seen Java programmers are not doing so well when asked to design and code a solution in a limited time, but at the same time, they are really good with Java concepts and all theories.

Since Java is also one of the most popular languages to develop backend services, there is a lot of demand for Java developers who know web services and can implement and expose existing SOAP-based services into REST style, light-weight web services.

Top 3 Servlet and JSP Books for Java Developers in 2025 - Best of Lot

I often receive a request from my readers and fellow Java developers about book recommendations to learn Servlet and JSP, two of the key web technology for server-side web development in Java. Unfortunately, there are not many good books to learn Servlet and JSP for Java web developers. Despite being the most popular Java Web technology, there are very few good books to learn Servlet and JSP. The one book which everybody will suggest to you is the Head First Servlet and JSP, which is indeed one of the best books but it's outdated now. It doesn't cover the latest development in Servlet API, particularly Servlet 3.0, and also not been updated for the last 7 to 8 years, but considering others, it is still an excellent book to learn Servlet and JSP.

2 Books to Prepare Java EE 6 Web Component Developer Certified Expert 1Z0-899 Exam (OCEJWCD)

Oracle launched "Java EE 6 Web Component Developer Certified Expert 1Z0-899 Exam" in 2011 to replace "Java Platform, Enterprise Edition 6 Java Server Pages and Servlet Developer Certified Expert Exam" and the "Oracle Certified Expert, Java Platform, Enterprise Edition 6 Java Server Pages and Servlet Developer" certification. They are the equivalent to the plain old SCWCD exam of the Sun Microsystems era. Frankly speaking, I always found sun naming less confusing and clearer than Oracle's e.g. SCJP was much better than OCAJP and OCPJP.

Top 4 Books to learn Oracle PL/SQL Programming in 2025 - Best, Must Read

In last summer, I had to work on a Java project which was using the Oracle database at their backend. The project was a mix of Java code with Oracle PL/SQL stored procedures, where Stored procedures were quite big and complex to read. I had not worked on Oracle for a couple of years and almost forget whatever I knew before. So, to revise, update and re-learn and I looked over some of the books and online courses like The Complete Oracle SQL Certification Course which helped me a lot.

Top 5 books to learn Agile and Scrum for Programmers in 2025 - Best of lot, Must Read

When I started my career, it was all waterfall model. You try, fail, and then with every version you get an improved version of the software. I pretty much used to this model of software development until I was introduced to Agile development methodologies in my next company. I was confused about Agile as some people say its Scrum and Sprint, other ways its XP and Kanban, etc. The confusion lasted for a long time because I was afraid of asking questions (afraid of being perceived as dumb and someone who wastes time on meetings) and only getting information in bits and pieces and I wasn't good at searching books at that time. From that experience, I learned that, when you have confusion and want to learn more about new technology, nothing is better than a book or online training courses to start with.

Top 5 C++ Programming Books in 2025 - Must Read, Best of Lot

Hello guys, I have started my programming career with C and C++ before learning Java, and it's been more than 11 years since I am using C++, though not as often as Java, which becomes my primary skill, my C++ knowledge has helped me to work on projects where both C++ and Java is used. Often time, I am rusty with C++ with very less coding, but whenever I have to refresh my knowledge, I have the right books to do so. I have used C++ on both professional and personal projects and mostly use a GCC compiler. If you ask me which one is tough to learn, C++ or Java? I would say C++? It's even difficult to master, and you cannot master it unless your coding C++ daily.

How to Crack Java Programming Interviews in 2025? Topics, Courses, Books, and Questions

Java Interviews are a little bit different than traditional programming interviews on tech giants and product-based companies like Google, Amazon, Microsoft, or Facebook. First, even though it has questions from Data Structures and Algorithms like String or Array, you can still manage to clear Java interviews if you are not an expert on them. The questions are a little bit easier and more practical than those companies. Another essential thing about Java interviews are questions based upon Java programming language and JDK API. Since Java is also an Object-oriented programming language, you will find lots of OOP questions there.

Top 10 Free Java Programming Books, EBooks and PDF for Beginners and Experienced Programmers

Who doesn't like free stuff? Well, I do like and many Java programmers like me simply love free Java books, eBooks, and PDFs. Fortunately, the Internet is full of free books and eBooks but unfortunately, many of them are of not good quality. Most of the eBooks which are freely available either are sample chapters of popular Java programming books or they are simply old and out-of-date. In my last article, I have shared a lot of such books and the feedback was that most of them, even though they are good in the past, have simply not up to the mark. The search goes on and while browsing the net a couple of days back I hit the jackpot when I found these free Java books from O'Reilly.

Top 5 Data Structure and Algorithm Books - Must Read, Best of Lot

Data Structure and Algorithms books are often taught as textbooks in various universities, colleges, and Computer Science degree courses, yet, when you put programmers in a situation, where they need to find and decide, which data structures and algorithms to use to solve a problem, they struggles. I have seen this, and I think one reason for this is perspective. When you read something like a textbook and your perspective is just to do well in the exam, you might not be thinking about learning and applying that knowledge to real-world problems. Since data structures and algorithms are the core of any programming problem, it becomes extremely important for programmers to master them even if you have learned well during academics.

Is "Java Concurrency in Practice" still Valid in the Era of Java 23?

Hello guys, one of my reader Shobhit asked this question on my blog post about 12 must-reads advanced Java books for intermediate programmers - part 1. I really like the question and thought that many Java programmers might have the same doubt whenever someone recommends them to read Java Concurrency in Practice. When this book came first in 2006, Java world was still not sure of about new concurrency changes made in Java 1.5, I think the first big attempt to improve Java's built-in support for multi-threading and concurrency.

The OCAJP 1Z0-808 - Best Books and Mock Exams for Java 8 OCA Certification

From the last couple of months, I have been helping a few developers to prepare for Java 8 associate certification with exam code 1Z0-808, also known as OCAJP 8. From my experience, both for preparing for Sun certification and helping other developers to get Java certified, I can say that two keys to be successful in Oracle Java SE certification are choosing an excellent study guide/course and buying one or two top quality mock exam simulators. When I say success, it doesn't mean just passing the exam but scoring above 90% because passing score 65% is not very difficult to achieve and anybody can pass OCAJP 8 by just a couple of month of practice but to score 90% and above is not that easy, you need to prepare and prepare hard.

2 Books to Prepare Oracle Java Certification Exams - OCA and OCP Java SE 6,7, 8 OCPJP 8

There was a time when Sun Certification was very hot and programmers feel proud of being Sun Certified Java Professional(SCJP). After Oracle took over Sun in early 2010, it changed names of all the examination from SCJP to OCPJP or OCJP, and now OCA and OCP for Java SE 7 and Java SE 8. I see there is a lot of confusion among certification nowadays, but essentially they are of the same level at previous SCJP. Since Java gets new language features with every new release, subsequently a new certification title is introduced. I am not agreed with upgrading your Java certification with every release, it doesn't make much sense to me, but many programmers prefer to get certified and keep it updated.

Grokking The Java Interview - My First Book After 10 Years as Java Blogger

Top 5 Books to Learn SQL and Database Design for Programmers and DBAs - Best of Lot

The database design and modeling are one of those topics which rarely get the attention they deserve, especially at the start of the project, but once things have gone out of hand, then everybody talks about them. Comments like - this database is designed poorly, the schema is not performing well, you cannot add a new column easily, etc. becomes very common. The most problem with database design is that it is mainly done by application developers like Java or C++ developer who knows SQL, but they are not the expert on how to design tables and schema. 

Top 5 Java Performance Tuning Books for Experienced Programmers - Best of Lot, Must read

You might be thinking, why should a Java developer read a book on Performance tuning? When I first faced this question a long time back, I thought I will do it later, but I never got back to that for a long time. I realize my mistake of having a lack of knowledge on memory measurement, JVM tuning, and finding bottleneck only when I faced severe performance and scalability issues on our mission-critical, server-side financial application written in Java. It's true that when you really need it, you learn most, but those times are not the best time to learn fundamentals, in fact, those times are to apply and correct your misunderstanding.

Top 3 Books to Learn Java for C and C++ Programmer?

In the last 2 decades, many Java programmers started programming with C and C++, but the situation is changed now, you have more choices like you can choose Python, or you can even start with Java. It seems Academia prefers Python in the USA and Java in India, but there are still many programmers who know C and C++ and want to learn Java for one or other reasons. I often receive emails from my readers about book recommendation, and recently, a couple of them asked me to suggest the best Java books for C and C++ programmers. I can relate those beginners to myself because I have also gone through the same phase, but those days, the university textbooks are our only source to learn new things. We didn't have broadband, and unlimited access to the Internet and eBooks was not popular at that time, but things have changed.

Top 5 Software Development and Project Management Books - Best of Lot, Must Read

Hello guys, if you are looking for Software development and Project management books then you have come to the right place. Earlier, I have shared Software development and project management courses and today I am going to share best books you can read on Software development and project management. You may be wondering, Why software development project managers should read books? Isn't they are experienced enough to become a project manager and handle software development and manage Programmers? A genuine question, but Software management is harder than any other management purely because every Software or Project is different than the previous one. Many other streams of engineering, like Civil or Mechanical, got better in terms of estimation and management with the help of software, but software development is still run on experience.
