A Better way to write Complex SQL queries for Programmers

There is no doubt that writing code is more art than science, every coder cannot write beautiful code which is both readable and maintainable, even with experience. In general, coding improves with experience when you learn the art of coding e.g. favoring composition over inheritance or coding for interface than implementation, but only a few developers able to master these techniques.  The same applies to SQL queries. The way you structure your query, the way you write it goes a long way to communicate your intent to the fellow developer.

How to reverse an ArrayList in place in Java - Coding Interview Questions

You can reverse an ArrayList in place in Java by using the same algorithm we have used to reverse an array in place in Java. If you have already solved that problem then It's a no-brainer because ArrayList is nothing but a dynamic array, which can resize itself. All elements of an array are stored in the internal array itself. By the way, if you need to reverse an ArrayList then you should be using the Collections.reverse() method provided by the Java Collection framework. It's a generic method, so you can not only reverse an ArrayList but also Vector, LinkedList, CopyOnWriteArrayList, or any other List implementation.

How to Print Fibonacci Series in Java without Recursion - Coding Problem for Beginners

Fibonacci series is a great example of Dynamic Programming, Recursion, and how the use of Recursion can result in a clear and concise solution.

The interviewer often challenged this practice by asking candidates to implement the Fibonacci series without using recursion. Yes, you read it right, you can't use recursion and this is what you will learn in this article. If you have attended your programming classes regularly then you may know that many recursive algorithms also have their iterative counterpart which uses loops instead of recursion or calling itself. We will take advantage of that concept to devise a solution to this problem.

How to write a C like Sizeof function in Java?

If you have just started learning Java and came from C background then you might have noticed some difference between Java and C programming language, e.g., String is an object in Java and not a NULL-terminated character array.

But if you are missing sizeOf operator then why not let's make it a coding task? If you are Ok, then your next job is to write a method in Java, which can behave like sizeOf() operator/function of C and returns the size in bytes for each primitive numeric type, i.e. all primitive types except boolean.
