In this article, we will learn how to compare strings in Java using the compareTo() method and the == operator. These methods help in checking string values and references. comapareTo() method The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string. The == operator: You can compare two strings using the == operator. However, it compares references to the given variables, not values. ... Read More
Do you feel like your CPU usage is high on your PC and that is interfering with its performance? Now, you open up the task manager only to find out a number of applications running. But to your surprise, you are not actively using any of them. The applications performing operations in the background on your computer are often called background applications. You might be looking for an easy way out of this situation and therefore landed here. So, we are glad to tell you that we not only have an ... Read More
boundary elements of a matrix The boundary elements of a matrix are those elements that lie along its edges. A matrix is a two-dimensional array that can be of any given size. The boundary elements are those present on the edges of the matrix. Problem Description We are given a matrix of size m × n. We need to find the boundary elements of the matrix. Boundary elements are the elements present on the top and bottom rows and the first and last columns of the matrix. Below are examples to understand the boundary traversal of a matrix: ... Read More
Cartesian-coordinate System and Quadrants The cartesian-coordinate system is divided into four Quadrants: Quadrant I, Quadrant II, Quadrant III, and Quadrant IV. In this article, we are going to learn how we can determine the quadrant in which given points i.e., x and y, lie. Problem Description We are given the position of a point (x, y), and we have to determine in which quadrant this point lies. Example Input: (-3, 2) Output: Quadrant II Input: (2, 5) Output: Quadrant I Input: (2, -4) Output: Quadrant IV Input: (-6, -3) Output: Quadrant III Using Conditional Quadrant Identification Approach ...

When we start learning to code, practicing star patterns is one of the best ways to improve logic building. One of the engaging patterns is the parallelogram pattern. In this article, we are going to learn how to print a Parallelogram Star Pattern using C++. What is Parallelogram Pattern? A parallelogram pattern is a geometrical arrangement of stars in a parallelogram shape. The stars are printed in such a manner that if we draw a closed figure on the boundary of the printed pattern, it will resemble a parallelogram. Each row is shifted with space, which creates a diagonal ... Read More
To insert spaces/tabs in text using HTML and CSS, can be tricky as HTML generally doesn't recognize multiple spaces or tabs by default. If you add extra spaces in your code, they'll collapse into a single space when displayed in the browser. We will be understanding three different approaches to insert spaces in text. In this article we are having some text content, our task is to insert Spaces/Tabs in text using HTML and CSS. Approaches to Insert Spaces/Tabs in Text Using HTML Entities for Spaces Using CSS margin or ... Read More
To convert JSON string to array of JSON objects using JavaScript is necessary because JSON strings can not be directly modified or manipulated, so we need this conversion which allows us to access, modify and iterate over each item. We will be discussing three different approaches for this conversion from JSON strings to array of JSON objects. In this article we are having JSON string, our task is to convert JSON string to array of JSON objects using JavaScript. Approaches to convert JSON string to objects Here is a list of approaches to convert JSON string to array of JSON ... Read More

JSON files are used in APIs to transfer data from server to client in the form array. This transferred data needs to be displayed in the user interface, such as in tables or any other components. In this article, we will demonstrate how to display JSON data using a React Table. Prerequisites To display a JSON file in React.js, we need to have a basic understanding of the React.js library. Basic knowledge of React, useState Hook, and useEffect Hook. Ensure Node.js and React are installed on your system. ... Read More
Unique IDs are used to differentiate multiple elements from each other, maintain the internal state of components, or create a key for user data. In this article, we will explain all the approaches to creating unique IDs for a set of elements in React JS. Approaches to Create Unique ID in React JS Here is the list of approaches for creating unique IDs in React JS, which we will be discussing in this article with stepwise explanations and complete example codes. Using uuid Library Using Timestamps ... Read More
