JAR. JAva aRchive. This is a file format that allows you to package your Java code into a single file format. This file format can be be used for storage or it can be runnable. Runnable meaning, with the click of a button it will launch your application (just like those icons on your desktop).
Having a JAR file provides a simple way for us to package our code. It comes inbuilt with compression to reduce the size of code and makes it easier to transfer code across mediums due to the file being a smaller singular one.
Is it just me? I like to try cool, fun stuff in Python. One of the most useful programs I have ever written is a PDF merger. The inspiration came as a result of needing to combine several PDFs together all at once without overriding any existing PDF resource.
To make our life easier, I will be using the PyPDF2 library. The GIF below exhibits the process of installing the library using the
pip install PyPDF2 command. The PyPDF2 library handles all the intricacies of merging the PDF files. …
Have you ever had the trouble of making an HTTP request to several different Application Programming Interfaces (APIs)? Wouldn’t it be easier to combine only what you need from these different APIs into a single API?
Creating a middleware can solve this issue. A software application middleware allows us to have a single customized source of data. One of the major benefits of having a middleware is that it connects many different products and services together in a shared system. So, what exactly is a middleware? According to Microsoft Azure, a middleware is a software operating as a hidden translation…
I don’t know if it’s how I was taught Java but my go-to method of running it is through the terminal. I enjoy the “hacker vibe” you get from being able to just use the keys on your keyboard to control the execution of a program.
In this article, I will be sharing how you can run your Java programs inside the command line.
Note: This demonstration will be done on a windows machine.
Running your Java programs from the command line gives an appreciation to…
Spring is a framework that allows you to create enterprise-level applications. The problem arose where it took many configurations to get an initial application up. This is where Spring Boot came along.
“Spring Boot allows you to abstract (hide) these configurations. So you can get a preconfigured template application.” — From part 1 of this series
Here in this article, you’ll be shown how to create a Rest API in Spring Boot. This API will be a CRUD (create, read, update, delete) application that connects to a SQL database — in this case, a MariaDB database.
If you’re new to…
You might have seen this one before: the syntax which often gets ignored because it doesn’t seem to hinder the execution of your code. It may not seem necessary, but that’s only if you’re working with a single Python file.
Let’s start out by deconstructing the statement from left to right. We already know what an if statement is; however, the most important part of the statement are the two things being compared.
Let’s start with
__name__ .This is used to denote the name of the file that is currently being run, but there is a trick to this. …
In this article we’re going to demonstrate how to generate dummy data and input for a MySQL database. Majority of the times we need to create a database to test some software that we’ve built. To do this, we can use Structured Query Language (SQL) to create a mock database system. However, problems may arise if we want to test hundreds or even thousands of records. There is definitely no way we could write that many insert statements into our SQL scripts to meeting our testing deadlines for product deployment, that would be too tedious and time consuming.
That can save you a lot of time !
Using python over the years, I came across some useful features that would have saved me a lot of time if I had known about them a little bit earlier. These little python gems can help keep your code more DRY( Do Not Repeat Yourself) and clean.
By the time you are finished with this article, I can guarantee you that you will be using some of these features in your very own python programs.
Note: You can use any IDE or text editor that you are familiar with ( python’s…
As developers or programmers, call yourself anyone. As long as you write code there is often one thing that gets overlooked. Testing. Testing is that part of development where you’re suppose to rigorously test your applications to ensure that they meet the required functionalities.
Let’s start of with why we even do testing in the first place:
Enjoys creating software that make tasks simpler. Always trying to gain new knowledge and expertise.
