There are multiple techniques shared on the internet on how to improve logical thinking or # logic building tips for programmers or how to think like a programmer. But those techniques does not work. I mean they work but... the hard way. It is like someone is asking you to taste a delicious food without opening your mouth. Can you do that? Probably you can come up with a super creative way but that's not the way it works. There is one most important process to follow before applying those techniques. You can say, it is a prerequisite to fully utilize those logic building technique. And it is, understanding the flow of data inside your code. The code that you haven't written yet. Wait... What?
I am not kidding. You can understand your code that does not exists yet by using your imagination power. The power that makes us human, human. If you want something done and you cannot imagine it, you will never get it done. Here, I will tell you how programmers in the beginning develop …

How To Become A Successful Programmer? I have heard many novice programmers saying I want to get better at programming but there is hardly a slight improvement in their skills. I have observed that most of them say they want to get better but that is just a wish. They do not really mean it. They mere wish to improve their skills. They do not work for it. Your wish does not guarantee that you will become a successful programmer. Many other people who have developed an interest in computer programming do not know how to reach to a point where they will be called successful programmers. They either keep wandering in the middle of nowhere or just give up. The same response is for them too as it was for the wishers. Your interest does not guarantee that you will succeed. Programming is a field which requires intensive work to master. Along with improving your technical knowledge of programming, you need to work on your interest. You need to develop a habit of not giving up. You need to…

If you are thinking how does this image relates to the topic, don't think. Keep calm and keep reading. What is function overloading? Function overloading is a concept in programming where there are multiple functions with the same name having different parameters. Different parameters mean either the number of parameter is different or the data type or the order of input parameters is different. If the names of multiple functions are the same then how does a compiler/interpreter recognize which function has been called? Recall function signature from the previous post. Compiler recognizes each function by its signature and function signature includes function name, number of parameters passed to it, their data type and the order in which they are provided. Each version of an overloaded function is almost same for us but entirely a different function for compiler. It just executes the function to which a call has been made irrespective of it is an overloaded function or not provide…

Types Of Functions In Programming: In previous post we briefly discussed what are functions in programming and how to use them  in a generic way. Here, you will learn what are different types of functions.
Functions are divided into two categories based on where their definition exists.
Built in functionsUser define functions 1. Built-in Functions Built-in functions are those which are already defined in a library. All you need to do is to import the library and call the function. There is no need to define and declare the required function. Steps to use Built-in function: Each and every language has a rich set of libraries developed for specific purposes. It is really hard to remember all of these libraries and functions and there is no need to remember at all. Here are listed some steps that I would suggest you to find a library and its functions for certain task. Understand both the problem and your solutionSearch a library suitable for your needFind your required function and read…

What is a function in programming? A function in computer programming is just a block of related and reusable code which performs a single task or activity.
Function is also called method, procedure, sub-routine etc. I will try to cover each and every aspect of functions here. I have divided this post into two sections. One section explains the structural components and the other explains non-structural components. I am categorizing these things because I think it will help you better understand functions. These categories are not official. Tell me in the comments whether you liked the categorization or not. Based on your response, I will update this post. Structural Components:  There are four structural components of a function: NameBodyInputOutput 1. Name: Function name is the same as a variable name. It follows the same conventions a variable name follows. Special characters and spaces are not allowed in function name. Name of a function is used latter in the code to call/execute t…

If you are intrigued by the title and you are reading this, it means that you are interested to learn how to code. You might have heard people saying that programming is a God gifted skill and not everybody is blessed with it or programming is not for people like you or me or whatever. Believe me, that's bullshit. Computer programming is the most interesting and the easiest skill to acquire in computer sciences. At least, I think so. It is said that one can do almost everything with programming and its true. If you can do everything with something, it then definitely worths a lot of your time. A question arises here that how much time one should dedicate daily to learn how to code fast and effect? I would say 8 hrs if you are on your own. To reduce the time and effort you need to learn programming, you should benefit from those who have experience and are good at it. As far as I think, you can boost up your learning process if you learn the basics well. Different authors have a d…

Machine learning has seen enormous growth in recent years. It is actively transforming every industry all around us. From autonomous vehicles to chess players, a simple path following robots to Sophia and from recognizing horrible handwritten text to extremely intelligent new Google Assistant, Machine Learning is everywhere. Thanks to Big Data, high power CPUs, giant GPUs and of course to researchers who brought ML from something to everything. For raising reality straight out of a fantasy (sounds filmic. Doesn't it?). Thanks for saving us from the thing that most of the real human being hate. I'm talking about the holy MATHS. Ok, enough.

The blessed and the noble human (researchers and innovators) are working hard to come up with more accurate and efficient techniques which work in a constrained environment. One of the major efforts of ML & JS communities is to let us implement ML in JavaScript using JavaScript machine learning libraries. If you are a JavaScript Ninja an…

JavaScript has been a favorite language to developers throughout recent few years. It was initially supported by web browsers but soon after its release, server side implementations of the language were introduced by different organizations like Netscape, Microsoft and the open-source Node.js. It is not only used for designing webpages but for databases, server scripting and for mobile and desktop applications too. One of the most prominent reasons to learn JavaScript is its enormous community and its products. There are a number of cool JavaScript libraries which makes the life of a developer very easy. ECMA International has introduced the ECMA2017 standards which are quite effective and saves enough amount of time. With all this, the community has made large efforts to bring Machine Learning and JavaScript together. Taking all these into consideration, JavaScript seems worth our time.

If you are a beginner or an intermediate JavaScript developer, we suggest you some books which yo…

Is it enough to learn a single programming language and live with it?

Like working in a single language for the entire life? Oh C’mon

My answer is big NO. I mean not at all. A single language can work pretty much everywhere but one language that performs well somewhere does not mean that it will perform that much good elsewhere. There is always a better choice available.

For example JavaScript works best in web applications but it won’t work the way Python woks for Data science. I hope you got the point.

To get your hands on a well-paid job, or to make an attractive freelance profile or to pursue further studies in computer you should master one and get familiar with at least 3 languages.

Let’s throw the blue collars, white collars, t-shirts and whatever out of the scope of this article and focus on students only.
If you have read my previous post, if you haven’t then I would recommend you read it first, then you should have got the idea that it is pretty handy to end up with many ch…

It is almost end of 2017. The computer has evolved throughout its age from a simple, huge machine which was used for just simple numerical calculations to a small and swift electronic device which is affecting almost every aspect of our life. There are a lot of efforts involved in these enhancements in both hardware and software. Powerful hardware has been invented, and robust software techniques have been designed to improve hardware efficiency. One of these methods is multithreading and this is what we are going to talk about.
Multithreading is the ability of a single processing unit to execute multiple programs concurrently, apparently supported by the operating system. Multithreading is achieved either by multithreaded architecture or by software techniques or by both. All processors and OSs today support multi-thread execution.
We are talking about multithreading but what actually a thread is? A thread is a single unit a single processor can execute. The group consists of the sh…

You are in college now so I am skipping the basics the go to class do your homework study for tests stay out of the hospital. These are not all important pieces of advice but I am sure you have heard them. Instead, let’s talk computer science. Here are some tips I have specially collected by talking to students who wish they’d heard them when they were students. Listen up.

Seek help when you need it. Your classes are going to get harder, they are going to test your knowledge but that’s why you are there for. Some people find attending office hours or seeking extra help to be embarrassing. But these resources are there for a reason. Taking advantage of the help you are offered will not only help you prepare for future classes and learn the material better but a lot less harmful than bad grades or any other consequences of struggling.Don’t let yourself intimidated by large projects. The best thing to do, sit down a day at the assignment and break it up into smaller tasks. A lot of times…

JAVA SE does not have any internal package for processing JSON data. We have to import an external library. There are many libraries available. You can choose any. I will use Json-simple1.1 here. This makes our first step, importing the lib.
Importing the libClick here and download the zip file containing the jar library and follow the following steps to import it into eclipse.
1.Extract the zip file.
2.Right Click on the project folder in the package explorer, hover over Build Path and click on Configure Build Path.
3.You will see a nice window. Go to the Libraries tab and click on Add External JARs.
4.Navigate to the extracted jar folder, select the library and press open/ok.
5.Press ok again and you are done.
Exploring the lib The library contains parser and data structures to process the given JSON formatted string. The parser parses the JSON data from string/Reader to its own readable form. The data structures consist of JSONObject and JSONArray Classes which store JSON Objects …
