As we know, both Java and JavaScript are programming languages and are used in application development. But there are significant differences between the languages, which we will discuss below. Java Java is a high-level language that is also a platform-independent language. It is mainly used in the development of web applications, mobile applications, games, etc. Java is a statically typed language, which means that the code must be checked for errors before it runs. JavaScript whereas JavaScript is a dynamically typed language, which means that the code is checked for errors while it runs. JavaScript is a client-server-side language, which ... Read More
Both Servlets and JSP are used in web development. The Servlets handle the logic (processing our requests and interacting with databases), and JSPs handle the presentation (displaying dynamic content on the web page). By separating the logic and presentation, our web applications become more manageable and scalable. In brief, we can think of Servlets as Java programs that run on a web server. They work as the middle layer between a request from an HTTP client (like a browser) and databases or applications on the server. When we send a request to a server, the Servlet processes that request, and ... Read More
Users can not directly use if/else condition in CSS. For conditional styling in CSS, we have to use alternatives of if/else condition. We will be understanding three different alternate ways to use conditional styling in CSS. In this article, our task is to implement if/else condition in CSS. Since if/else condition is not supported in CSS, we will be understanding its alternate approaches. Approaches for Using Conditional Styling in CSS Here is a list of approaches for using conditional styling in CSS which we will be discussing in this article with stepwise explanation and complete example codes. ...

Centering the middle item in a layout while ensuring it doesn’t move if other items are removed is a common design challenge, this article explores ways to center the middle item using CSS techniques that maintain its position even if adjacent elements are absent. Using Flexbox with Absolute Centering Flexbox offers a straightforward way to center an item within a container. By setting the middle item to have margin property set to auto, it remains centered without depending on adjacent items. Example Code ... Read More
Working with web applications often requires parsing some HTML tables to extract the content in the appropriate format, most often in JSON format which is better for storage, transfer, or API communication. One of the most popular formats used for data exchange is JSON, mainly due to its lightweight nature and ease of integration on the front and back end. This article highlights different methods for making a JSON representation of an HTML table in JavaScript. Approaches to Convert HTML Table to JSON Using JavaScript’s querySelector and loops. Using forEach ... Read More
In this article, we will go over a Java program that counts the number of child nodes of the root node in a JTree using Java. This program uses the getChildCount() method to retrieve and display the count of direct child nodes under the root. This is helpful for applications involving hierarchical structures, like directories or organizational charts. Steps to count the child of the root node in a JTree Following are the steps to count the child of the root node in a JTree −Import the necessary classes JFrame, JTree, and DefaultMutableTreeNode from java.swing package.Create a main class named SwingDemo.Define the ...

This article will teach us to convert a string into a numeric primitive type using Integer.valueOf() in Java. By the end, you’ll see how this method takes a string of numbers and transforms it into an integer type, making it usable for arithmetic operations or any other number-based logic. Problem Statement Write a Java program to convert a numeric string to an integer using the Integer.valueOf() method and display the result. Below is a demostration of the same − Input str = "989" Output 989 Steps to convert a string into a numeric primitive type Following are the steps to convert a ... Read More
Mean, Median, and Mode are key statistical measures that help in describing a dataset's central tendency and distribution. These quantities help in understanding the central tendency and distribution of the given data. In this article, we will learn how to find the Mean if the Median and Mode of a given array are known in C++. Problem Statement We are given an array of numbers, and we need to find the mean if the median and mode are provided in C++. Example Input: [5, 15, 25, 35, 35, 40, ... Read More
In this article, we'll learn how to check whether the entered value is ASCII 7-bit alphabetic lowercase in Java. In ASCII, the lowercase alphabets begin with the character ‘a’ and end with ‘z’. We will write a program checking whether a character is a lowercase alphabetic character using a simple if-else statement. Problem Statement We are given a character, and we need to create a Java program that checks whether the character is a lowercase letter in the ASCII 7-bit range, meaning it falls between 'a' and 'z'. We will also check if the character is uppercase, meaning ... Read More
In this article, we will learn how to create BigDecimal values in Java using strings. The BigDecimal class provides a way to handle large or precise numbers, making it useful for high-precision arithmetic. By creating BigDecimal objects from strings, we make sure that the exact number is represented without any loss of precision. Problem Statement Given two large decimal values as strings, write a Java program to create BigDecimal objects and perform addition and multiplication on them.Input Value 1: "37578975.8768"Value 2: "62567878.9768"Output Value1 : 37578975.8768 Value 2 : 62567878.9768 Addition Operation = 100146854.8536 Multiplication Operation = 6265976294387200.48179648 Steps to ...
