Python is a universal language that is used by both data engineers and data scientists and probably the most popular programming language, as well. All the Data Scientists I have spoken to, and many in my friend circle just love Python, mainly because it can automate all the tedious operational work that data engineers need to do. To make the deal even sweeter, Python also has algorithms, analytics, and data visualization libraries like Matplotlib, which is an essential data scientist.

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which are freely available either are sample chapters of popular Java programming books or they are simply old and out-of-date.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.

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.
