The Structured Query Language (SQL) is widely used in databases to manipulate and manage data. When working with multiple tables we often need to combine or join data to retrieve meaningful information. The Two common types of joins used for this purpose are the Natural Join and the Inner Join. While both the join operations are used to combine data from two or more tables they have some differences in how they work. This article explores these differences in detail. What is an Inner Join? An Inner Join is the most commonly used join operation. It returns only those records ... Read More
With edge computing, data is handled as close to an IoT device. There could be benefits for business IT in terms of latency, productivity, cost, and security. IoT technology keeps getting better and more valuable, and the number of ways One can use it keeps growing. Edge computing is one of the most talked-about topics in the IT industry right now, and it's getting bigger and bigger all the time. But what is edge computing, and why should businesses care about it in the IoT? In the middle of a concept's meteoric rise to fame, its original meaning could be ... Read More
Cloud computing has emerged as a key element of novel concepts and digital change in recent years. Consequently, companies can now use remote devices to run their apps and services. As on-premises technology is no longer necessary, scalability, dependability, and cost have all risen. However, because more people want real-time data management and more Internet of Things (IoT) gadgets are being produced, cloud computing is finding it difficult to meet these demands. As a possible solution to these problems, edge computing is gaining more and more traction. Managing data closer to its source allows businesses to improve their operations. This ... Read More
Edge computing & 5G are two of the most essential technologies & the mixture of these two technologies has a high potential to transform the way IoT devices work, causing them more efficient, faster, & more reliable. In this article, we will examine how edge computing and 5G will help IoT. What is Edge Computing? A distributed computing paradigm known as edge computing enables data processing and storage to be carried out near the data sources, such as IoT devices, sensors, and mobile devices. This strategy aims to minimize latency, decrease bandwidth usage, & enhance overall performance & ... Read More
To iterate elements by className in JavaScript, we will be using getElementsByClassName() method. It is used for getting the collection of all the elements in the document with specified classname. In this article we are having three div elements each having same class name. Our task is to iterate elements by className in JavaScript. Approaches to Iterate Elements by ClassName Here is a list of approaches to iterate elements by className in JavaScript which we will be discussing in this article with stepwise explaination and complete example codes. Iterate Elements by ClassName using for loop ... Read More
By now, you must have gotten a clear picture of IoT and how it is aiding us by making our lives easier. IoT connects sensor devices and the internet for those new to this technology. These devices have sensors that collect the data and send it to the cloud over the internet. Now in the cloud, all the data processing happens. In simpler terms, sensors collect data and send it to the data centre, where it will be analyzed, and commands sent back to sensors. The entire process takes time, and processes are delayed. But then, how do we come ... Read More
In this article, we will learn to compute the sum of numbers in a list using Java with a while-loop. We will look at two examples: one that sums a list of integers and another that sums a list of double values. For each example, we will create an ArrayList to store the numbers, and then use a while-loop to iterate through the list. During the iteration, we will add each number to a variable called "sum, " which will keep track of the total. This will help you understand how to use loops and ArrayLists in Java effectively. Different ... Read More
In this article, we will learn to get the seconds since the beginning of the Java epoch. To get the seconds since the beginning of epochs, you need to use Instant. The method here used is ofEpochSecond() method. The epoch is the number of seconds that have elapsed since 00::00:00 Thursday, 1 January 1970. Get the seconds with ChronoUnit.SECONDS โ long seconds = Instant.ofEpochSecond(0L).until(Instant.now(), ChronoUnit.SECONDS); Stepsย to retrieve seconds since Epoch Following are the stepsย to retrieve seconds since Epoch โ First, we will import the Instant and ChronoUnit classes from the java.time and java.time.temporal packages. ...

In this article, we will learn to find the roots of a quadratic equation using Java. The roots of a quadratic equation are determined by the following formula: $$x = \frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$$ Here we will take input values for the coefficients ๐, ๐, and ๐ of the quadratic equation ๐ ๐ฅ 2 + ๐ ๐ฅ + ...
