To display both horizontal and vertical grid lines in a table, use the setShowGrid() method and set it to true − The setShowGrid() method is used in graphical user interfaces or data visualization tools to control the visibility of grid lines in a component, like a chart or a table. table.setShowGrid(true); JTable is a class in the Java Swing library, part of the JFC(Java Foundation Classes). It creates and manages tables in a GUI(graphical user interface) application. Syntax void setShowGrid(boolean showGrid) Parameter showGrid: A boolean that determines grid line visibility for both horizontal and vertical lines is true ... Read More
In this article, we will learn to count the number of undefined elements in an array using JavaScript. When working with arrays in JavaScript, you may encounter situations where certain elements are either explicitly set as undefined or are missing altogether (often represented by empty slots in sparse arrays). Problem Statement Given an array that may contain undefined values, we need to count how many elements in the array are defined (i.e., not undefined). Input const arr = [12, undefined, "blabla", , true, 44]; Output 44 elements are defined (12, "blabla", true, and 44). Thus, the expected output is ... Read More
In this article, we will learn the JavaScript equivalent of Python's zip Function In Python, the zip() function is a convenient way to combine multiple tables into a single iterable of tuples. However, JavaScript does not have a built-in equivalent for this functionality Problem Statement Given two or more arrays of equal length, implement a function in JavaScript that combines these arrays into a single variety of arrays, where each inner array contains the elements from the input arrays at the corresponding positions. Input arr1 = [1, 2, 3], arr2 = ['a', 'b', 'c']Output [[1, 'a'], [2, 'b'], [3, 'c']] ... Read More
In this article, we will learn how to iterate through all DOM elements on a webpage using JavaScript. By doing so, we can easily access and manipulate various elements of the page, whether for debugging, gathering information, or applying changes to the page's structure and content. We'll walk through a step-by-step process to loop through all elements and display the results in the console, helping you better understand how to interact with the DOM. What is the DOM? The Document Object Model (DOM) is a representation of the structure of a webpage. It treats each part of the webpage (HTML ... Read More
To check if a string can be formed from another string by at most X circular clockwise shifts, we can calculate the difference of ASCII value of the characters and then compare it with the X. Circular clockwise shifts for the string mean rotating the characters of the string to their next character in alphabetic order. In this article, we are given with a string, target and a number which represent the number of circular shifts to be made. Our task is to write a JavaScript program to check if the target can be formed from the string by at ... Read More
To cyclically rotate an array by one means shifting the value present at each index to their left or right by one. In this article, we are having an array and our task is to write a JavaScript program to cyclically rotate an array by one. Users must be familiar with JavaScript loops and array operations. Example Input: arr= [ 1, 2, 3, 4, 5, 6 ] Output: Left rotation: [ 2, 3, 4, 5, 6, 1 ] Right rotation: [ 6, 1, 2, 3, 4, 5 ] Approaches to Cyclically ... Read More
Sometimes, the margin-top in CSS doesn't work as expected. You might not see the space you want above an element, or it might not behave correctly. This can happen because of things like collapsing margins, the element's type, or how it's positioned. Our task is to show you how to make the margin-top style work using different approaches, so you can control spacing in your designs. Approaches to Managing Margin-Top We'll look at different ways to manage the margin-top property and control space between elements. Here are the methods to solve common margin problems: ...

Excel is a powerful tool widely used for data analysis, computation and visualization. While working with Excel, we use formulas and functions frequently. Read this article to learn how an Excel formula is different from an Excel function and what are their unique features. What is a Formula in Excel?A formula in Excel is a user-defined expression that calculates a value. Formulas are written by the user and can include cell references, constants, arithmetic operators and functions. Features of Excel Formulas Excel formulas are created manually by the user. They can combine values, references and functions. Excel formulas are tailored for ... Read More
Many developers struggle to create elements that fill the full height of the viewport, especially in responsive layouts, because they lack knowledge of using Tailwind CSS utilities. Tailwind CSS ensures responsiveness and user engagement by providing utility-first classes. What is viewport height? Viewport Height (vh) is a CSS unit that measures the height of the visible area of a web page in the browser window, excluding any scrollbars or toolbars. Approaches to fill viewport height We can fill the height of the viewport in Tailwind CSS using the following approaches: Using the h-screen class ... Read More
Problem Description In this problem, we are given two numbers, and we have to find the value obtained after subtracting one number from another. In this article, we are going to learn how we can subtract two numbers in C# using different approaches. Example 1 Input:number1 = 8number2 = 12 Output: 4 Explanation The subtraction of number2 - number1, i.e., 12 - 8, will result in 4. Example 2 Input:number1 = 10number2 = 10 Output: 0 ... Read More
