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.

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.
