In this article, we will learn to convert a java.util.Date object to a java.sql.Date object in Java. This is a common requirement when working with databases, as many database systems use the java.sql.Date class to represent date values. While java.util.Date is used for general date and time representation in Java, java.sql.Date is specifically designed to handle SQL-compatible date formats. java.util.Date The Date class in the java.util package representing a specific moment in time, measured in milliseconds since January 1, 1970, UTC (the "epoch"). It's a general-purpose date and time representation. java.sql.Date A subclass of ... Read More
Data breaches are the most common problem these days. With new emerging technologies, implementations are sometimes not done with proper security practises in mind, leading to data breaches. Organisations deploy every sophisticated product in the market, yet still, data breaches happen. Why? Human errors are the answer! In this article, let's explore why educating employees is the key to preventing data breaches in 2025 and beyond. What is a Data Breach? A data breach takes place when any private information is accessed by anyone without permission. This information or data can be anything such as your debit/credit card details, passwords, ...

Cross-site scripting (XSS) attacks are among the most common vulnerabilities found in web applications. An attacker attends a user's browsing session, often deceptively by propelling a malicious script, but the user is using a trusted site. The most important effect of XSS is that it allows an attacker to steal sensitive cookies by unauthorized acquisition, causing identity theft or session hijacking.What XSS attacks are, how cookies are compromised because of them, and most importantly, how to implement effective safeguards against the leaking cookies during such attacks will all be revealed in this article.What is Cross-site Scripting?Cross-site scripting (XSS) is a ...

It is vital in cybersecurity to learn how to prevent different types of cyber attacks. Many different mechanisms are used by attackers when targeting user credentials; two of the most common types of attacks are dictionary attacks and password spraying. Both of these try to penetrate a password, but their approaches and situations are quite different. In this article, we will examine the differences between these two attack methods, and we will also explore how they work and what are the preventive measures. What is Password Spraying? One of these attack techniques is called password spraying where an attacker ... Read More
There are times when you need to merge multiple Boolean arrays into a single array in JavaScript. One common approach is to combine the corresponding elements from each array using the OR (||) operator. This operation returns true if at least one of the elements being compared is true; otherwise, it returns false. In this article, we'll learn how to merge multiple Boolean arrays into a single array using JavaScript, specifically by applying the OR operator on corresponding elements. We will utilize the Array.prototype.reduce() function to efficiently perform this task. Problem Definition We are given an array of arrays of ... Read More
Overriding CSS in Tailwind can be difficult when the default utility classes don't fully match your design requirements. In some cases, you may need to adjust specific styles like background colors or margins without affecting the rest of the layout. So, in this article, I'm going to show you different ways to override CSS selectors in Tailwind, so you can make the changes you need without disrupting your design. Approaches to Override CSS Selectors in Tailwind In this section, we'll look at simple ways to override styles in Tailwind CSS. Each approach will help you customize your ... Read More
When working with strings in JavaScript, you might encounter scenarios where you need to clean or format text by removing specific portions. A common task is to remove text after a comma and the following word. This can be achieved efficiently using JavaScript Regular Expressions (Regex). In this article, we’ll show you how to do it step-by-step. Why Use Regex for Text Manipulation? Regex, short for Regular Expressions, is a powerful tool for pattern matching and text processing. It allows you to identify and manipulate text patterns with precision, making tasks like cleaning data or reformatting strings much simpler. How ... Read More
In this article, we will learn two different approaches to computing the focal length of a spherical mirror using Java. While the second method makes use of Object-Oriented Programming (OOP) concepts for a more generic and flexible approach the first method is a simple functional implementation. Finding Focal Length Spherical mirrors play a vital role in optical systems, from telescopes and microscopes to vehicle rearview mirrors. These mirrors, either concave or convex, focus or diverge light, respectively, based on their geometry. The focal length, a key characteristic of spherical mirrors, determines how the mirror bends light.The focal length of a ... Read More
In this article, we will learn to access browsing history using Javascript. In web development, accessing a user’s browsing history can improve user experience and provide personalized content. However, due to privacy concerns and security reasons, modern web browsers limit the amount of browsing history accessible via JavaScript. What is Browsing History? Browsing history refers to the list of web pages that a user has visited over a while. Browsers typically store this data locally, allowing users to navigate back and forth through the pages they’ve visited. The window.history Object In JavaScript, the window.history object allows interaction with the browser’s ... Read More
An interface with no methods in it is referred to as a marker interface, also known as a tagging interface. There are two basic design purposes of marker interfaces. Creates a common parent It is used to provide a common parent interface for a group of related interfaces. When an interface like "eventlistener" is extended by dozens of other interfaces in the Java API, we can use a marker interface to create a common parent among a group of interfaces. For example, when an interface extends EventListener, the JVM knows that this particular interface is going to be used in an ... Read More
