In this article we will learn to insert styled text into a JTextPane component in Java. The JTextPane component is a versatile text editor that supports rich text features, including the ability to style text with different fonts, colors, and sizes. By leveraging the StyledDocument and Style classes, you can insert styled text dynamically into a JTextPane using Java Swing. Insert styled text in a JTextPane component using the SimpleAttributeSet and StyleConstants classes. With that, we will also use StyledDocument. Java Swing The Swing API is a collection of flexible GUI components designed to simplify the development of Java-based front-end ... Read More
In this article, we will learn to calculate the product of the unique prime factors of a given number using Java. Prime factorization plays a crucial role in many mathematical and computational problems, and understanding how to work with prime factors can help you solve complex challenges efficiently. Problem Statement Given a positive integer n, the task is to find the product of the unique prime factors of n. The objective is to calculate the product of all distinct prime factors of n that divide it exactly. Input 68 Output 34 Since the unique prime factors of 68 are 2 ... Read More
In this article, we will learn to calculate the GCD of more than two numbers in Java. We will discuss two approaches, the recursive method and an optimized approach using the Euclidean algorithm. The Greatest Common Divisor (GCD) of two or more integers is the largest integer that divides all the numbers without leaving a remainder. When it comes to an array of numbers, finding the GCD means determining the GCD of all the elements in the array. Problem Statement Given an array of integers, find the GCD of all the elements.Example −Input {7, 49, 177, 105, 119, 42} Output ... Read More
In this article, we will learn to Submit a textbox by pressing ENTER in JavaScript. Submitting a textbox form by pressing the ENTER key is a common requirement in web development, enhancing the user experience by making interactions smoother and more intuitive. Why Enable Form Submission on ENTER Key Press? Allowing users to submit a form by pressing the ENTER key is an efficient way to enhance usability and reduce friction in the user interface. Whether you're building a search bar, login form, or any other type of text input, implementing this feature saves time and makes interactions feel ... Read More
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
