Why Every Developer should learn Cloud Computing (AWS, AZURE or GCP) in 2023

Hello guys, if you are wondering whether you should learn Cloud Computing in 2023 then my only advice to you is just learn it. It doesn't matter whether you are a Developer or DevOps, sooner or later you will have to learn Cloud, there is no escape here and learning now is your best option. Now most of the job description for Java developers list that they will prefer candidates with familiarity and experience working in cloud platforms like AWS or Azure and if you don't have them then you will be left behind. Nowadays, whenever I open LinkedIn, I see people on my network getting AWS certified or Azure Certified or Google Certified and its not a coincidence, they are doing because their job need Cloud skills and their companies are also encouraging them to learn Cloud and become a certified Cloud Developers and that's the main reason I suggest every programmer and developer to learn about Cloud computing.

How to use Recursion in JavaScript? Example Tutorial

If you are a programmer, you may have come across a term called “recursion”. In programming, several techniques are used to solve a problem. Recursion is one such technique. It allows you to break a big problem into smaller parts and then solve those smaller parts. It's also one of the useful techniques to solve dynamic programming-based problems and that's why it's very very important for any programmer or developer preparing for coding interviews.  Recursion is not limited to a specific programming language. It can be performed using Java, JavaScript, C, or any other programming language. In this article, we will learn what is recursion and how to perform it using JavaScript.

How to get the first and last item in an array in Java? Example Tutorial

Firstly, before going about finding the first and the last item of an array in java. We need to fully understand what an array is and how it works. What then is an Array? An array is a data structure in java that holds values of the same type with its length specified right from creation time. Think of a container, like a crate of eggs or coke. What I am trying to say is that when you are creating your array, the items coming in must be the same as you have specified as length and you must specify how many items are coming. If you have stated that the items coming are integers, so it is and no other data type (e.g string, char e.t.c) can be there and vice versa. Or you can say an array is a collection of similar type of elements which has contiguous memory location.

Java FileReader + BufferedReader Example

There are multiple ways to read a file in Java e.g. you can use a Scanner as we have seen in the last example, or you can use the BufferedReader class. The advantage of using a BufferedReader to read a text file is speed. It allows faster reading because of internal buffering provided by BufferedReader. Other Reader classes like FileReader access the file or disk every time you call the read() method but BufferedReader keeps 8KB worth of data in its internal buffer which you can read it without accessing the file multiple times. It's loaded when you access the file the first time for a subsequent read.
