Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. Identity matrix is a square matrix which has all 1s as its principal diagonal elements and rest are 0s. As per the problem statement we have to0 check if the given matrix is Identity matrix or not. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose we have a matrix ... Read More
There are many methods for creating new objects from older ones in JavaScript. Creating a new object with the same keys as an existing object but with all the keys in lowercase is a common use case. When working with data from many sources that have irregular key casing, this can be helpful. We'll look at various JavaScript ways to create new objects with lowercase keys in this blog post. However, before doing so, it's important to remember that while creating a new object with lowercase keys might be helpful when working with data from various sources, it's also ... Read More
Two elements giving the maximum sum in an array means, we have to find two largest array elements which will eventually give the maximum sum possible. In this article we will see how we can find the maximum sum of two elements in Java. To show you some instances Instance-1 Suppose we have the below array [10, 2, 3, -5, 99, 12, 0, -1] In this array the largest element is 99 and second largest is 12. Max sum = 99 + 12 Hence the maximum sum of two elements in this array is 111. Instance-2 Suppose we have the ... Read More
Backbone.js is a popular JavaScript framework that allows developers to create dynamic and interactive web applications Backbone.js's ability to build models that can be used to store and modify data is one of its primary strengths. In this article, we'll look at how to build a model in Backbone.js and how to apply it to a web application. Creating a Model Using the Backbone.Model class, you must first specify a new model before you can build one in Backbone.js. Here is an example of how to make a straightforward model called "Person" − var Student = Backbone.Model.extend({ ... Read More
Strong programming languages like JavaScript are frequently used to build interactive, dynamic web pages. The loading of images on a website is one of JavaScript's most popular uses. However, loading images might be challenging, particularly when determining whether a load is complete. In this article, we'll go through how to make a JavaScript callback that detects if an image has loaded or not. What is a callback function? A callback function is a function that is invoked after the initial function has finished running and is supplied as an argument to another function. To put it another way, a ... Read More
Two elements giving the maximum product in an array means, we have to find two largest array elements which will eventually give the maximum product possible. In this article we will see how we can find the maximum product of two elements in Java. To show you some instances Instance-1 Suppose we have the below array [10, 2, 3, -5, 99, 12, 0, -1] In this array the largest element is 99 and second largest is 12. Max product = 99 * 12 Hence the maximum product of two elements in this array is 1188. Instance-2 Suppose we have the ... Read More
Utilizing web technologies like JavaScript, HTML, and CSS, you can create cross-platform desktop applications using the popular framework Electron. This article will go over how to use Electron to transform an Angular 4 application into a desktop application. Setting Up Electron Before converting our Angular 4 application to a desktop application, we'll need to set up Electron. Here are the steps to set up Electron − Install Node.js Electron requires Node.js to be installed on your machine. You can download and install the latest version of Node.js from the official website. Install Electron Once Node.js is installed, you can install ... Read More
Electron is a popular framework for building cross-platform desktop applications using JavaScript, HTML, and CSS. In this article, we will explore how to generate PDF files in Electron using the jsPDF library. We will cover the basics of PDF generation, how to install and use the jsPDF library, and how to customize the appearance and content of the PDF. PDF stands for Portable Document Format). PDF is a file format used for representing documents that is independent of the application operating system, software and hardware that were used to create them. PDF files can be opened and viewed on ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Scalar multiplication is nothing but multiplication between a matrix and a real number. The result of this multiplication is in matrix format. As per the problem statement, we have to find the scalar multiplication of a matrix. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix ... Read More
As per the problem statement, we have given an array with some random integer values and we have to find out and print the index which contains any zero or negative values. Note - Take an integer array Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given Array= [1, 2, -3, -4, 0, 5] The index contains Zero and negative values = 2, 3, 4 Instance-2 Given Array= [-1, 0, 4, 6, 8, -5] The index contains Zero and negative values = 0, 1, ...
