How to declare and Initialize two dimensional Array in Java with Example

An array of more than one dimension is known as a multi-dimensional array. Two of the most common examples of multi-dimensional arrays are two and three-dimensional array, known as 2D and 3D array, anything above is rare. I have never seen 4-dimensional arrays, even 3D arrays are not that common. Now the question comes when do use a multi-dimensional array? Any real-life example? Well, 2D arrays are very common on platform games like Super Mario Bros to represent screen or terrain; 2D arrays can also be used to represent structures like a spreadsheet, or to draw board games like Chess, which requires 8x8 board, Checkers and  Tic-Tac-Toe, which requires 3 rows and 3 columns.

Top 10 Data Science and Machine Learning Certification Online Courses from Udemy, Coursera and Pluralsight - Best of Lot

If you work in the technology field today like you are a programmer or software engineer then I am sure you have heard about terms like Data Science, Machine Learning, Deep Learning, Artificial Intelligence etc. They are the latest technologies which are impacting every single sector just like IT does it when it comes the first time. It doesn't matter if you are working for a bank or insurance sector, airspace or defense, all fields were impacted by IT and in near future, they will be impacted by machine learning and artificial intelligence. If you are wondering, let me give you a brief overview. Machine learning is all about training machines to do the job which was only possible by humans before, for example seeing a photo and recognizing what is the object like a car, a human or a cucumber.

How to find Nth Fibonacci Number in Java - Coding Problem with Solution

It's been a long time since I have discussed a coding problem in this blog. So, I am going to start with the probably the oldest one of them, how do you find the nth number in a Fibonacci sequence? or how do you find the Fibonacci number in Java? or maybe printing the Fibonacci series. If you are a regular reader of this blog then you might know that I have already discussed both recursive and iterative algorithm for printing Fibonacci series but never really discussed especially writing a program to return the Nth Fibonacci number in Java. Don't worry the wait is over as in this article, we'll solve this common problem and learn a bit more about problem-solving, recursion, iteration and some basic algorithm skills.
