When working with Next.js, the Image component offers features like optimization, responsive sizing, and lazy loading for better performance. However, styling these images with Tailwind CSS while keeping the code clean and ensuring image optimization works can be challenging. Our goal is to show the best ways to use Tailwind CSS with the Next.js Image component for better performance and design. We'll go through a few examples to show how to style and optimize images using Tailwind and Next.js. Setting Up Tailwind CSS with Next.js To get started, you first need to install Tailwind CSS in your Next.js ... Read More
In this article, we use the trim() method to remove whitespace at the beginning and end of a string. This method does not modify the original string; instead, it returns a new string with the leading and trailing whitespace removed. Let’s say the following is our string with whitespace − string = " Tutorialspoint "; Now, let us trim all the whitespaces from the beginning and the end. String trimmed = string.trim(); Removing whitespace using trim () Method The trim() method in Java is a built-in function of the String class that removes ... Read More
Sometimes we are given an object and we want to extract only the key-value pairs that meet certain criteria. In this article, we are going to discuss how we can filter objects by values in Lodash. Prerequisite Lodash: Lodash is a popular JavaScript library used to deal with a variety of functions such as arrays, objects, strings, and more. Install Lodash We can install the Lodash library in the project by adding it via CDN or npm using the following command: npm install lodash Approaches to Filter Object by Values ... Read More
When using Tailwind CSS, the styles can apply to your whole website or app, which can cause issues if they affect areas you don't want. This happens because Tailwind's utility classes are global. So, how can you control where these styles are used? In this article, we'll show you different ways to make sure Tailwind CSS only affects certain parts of your site, making it easier to manage and preventing unwanted changes. Approaches to Scope Tailwind CSS There are several methods you can use to limit Tailwind CSS styles to specific parts of your website or app, making ... 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 ... Read More
Problem Description We are given an array that contains numbers from 1 to n, and one number is missing between the given numbers from 1 to n. We have to return the missing number in O(1) time complexity. In this problem, we are going to discuss how we can find the missing number in an array. Example 1 Input: array = {1, 2, 3, 5, 6, 7} Output: 4 Explanation From 1 to 7, the number 4 is missing in the given array. Example 2 ... Read More
ResultSet holdability determines whether the ResultSet objects (cursors) should be closed or held open when a transaction (that contains the said cursor/ ResultSet object) is committed using the commit() method of the Connection interface. The setHoldability() method of the Connection interface is used to set the holdability of the ResultSet objects in this connection (created using this connection) to a desired value. Syntax Following is the syntax of the Java Connection setHoldability() method − void setHoldability(int holdability) throws SQLException; Parameters This method accepts an integer value named "holdability", which is described below − Representing the ResultSet ...

In Java, the HashMap class is a part of the Java.util package and provides a convenient way to store key-value pairs. Sometimes, We need to update the values of existing keys while keeping the keys identical. This can be easily achieved using the put() method, replace() method, and computeIfPresent() method which allows to replace the value with a specific key. Creating a HashMap and setting key-value pair − Mapmap = new HashMap(); map.put(10, "A"); map.put(20, "B"); map.put(30, "C"); Now, let's set a different value for an identical key using the put(), replace(), and computeIfPresent() methods − map.put(10, "T"); map.replace(10, "T"); map.computeIfPresent(10, ...

In Java, converting a string to lowercase or uppercase is a common operation used in text processing, formatting, and case normalization. The String class provides built-in methods to achieve this with ease. This article explores how to use these methods with practical examples, demonstrating step-by-step how to convert strings between uppercase and lowercase. Key Methods toLowerCase(): Converts all characters in a string to lowercase. toUpperCase(): Converts all characters in a string to uppercase. These methods are part of the java.lang.String class and work seamlessly for any string input. Using toLowerCase() ... Read More
In this article, we will learn to convert an array with a null value to a string in Javascript. Handling arrays containing null, undefined, and falsy values in JavaScript is a frequent challenge. The default methods might not behave as expected when converting such arrays to strings, requiring custom solutions for meaningful string representations. Problem Statement Given an array containing null, undefined, empty strings, and other values, the task is to concatenate its elements into a single string while excluding the unwanted values. Following is our array, with some null and undefined values − Input ["Here", "is", null, "an", undefined, ... Read More
