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. That's why whenever asked about writing a Java program to get Fibonacci numbers or print the Fibonacci series of certain numbers, it's quite natural for programmers to resort to recursion. 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. Similarly, there is is no sizeof() operator in Java. All primitive values have predefined size, e.g., int is 4 bytes, char is 2 byte, short is 2 byte, long and float is 8 byte, and so on. 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.

What is the Use of DispatcherServlet in Spring MVC Framework?

If you have worked with Spring MVC then you should know what is a DispatcherServlet? It's actually the heart of Spring MVC, precisely the C of MVC design pattern or Controller.

It is also the bridge between Java and Spring.
