JRE stands for Java Runtime Environment. It is mainly a part of the Java Development Kit (JDK). It is free of cost so we can easily find it on any software to use in our program. It consists of a Java class library, specific tools and many more important tools. JRE can be implemented on any operating system and it works as an outer layer of the operating system. It also consists of Integration Libraries and base libraries such as Java Database Connectivity (JDBC), Java Naming and Directory Interface (JNDI), Java Management Extension (JMX), Java Native Interface (JNI), Java for ...

MATLAB programming allows us to automatically maximize an image for better visibility. For this, we can use the “figure” function with some arguments which described in the following syntax. Syntax figure('units', 'normalized', 'outerposition', [0 0 1 1]); The “figure” command with all these parameters automatically maximizes an image. The following MATLAB program demonstrates the implementation of a code to automatically maximize an image. MATLAB Program Example % MATLAB program for automatically maximize an image % Read the input image img = imread('https://www.tutorialspoint.com/assets/questions/media/ 14304-1687425236.jpg'); % Replace 'your_image.jpg' with the path to your image % Display the original image in ...

JAVA is a robust, portable and highly secured programming language created by James Gosling at a company named Sun Microsystems, Inc. in 1991. The official name of this is OAK, Sun Microsystems renamed it JAVA in 1995. This company was taken over by Oracle Corporation. It is an all-purpose programming language and it is also an object-oriented programming language. JAVA is a widely used programming language in modern days. It contains various safeguards intended to prevent crashes at the time of program running such as Collection of garbage- no invalid addresses, checking of array and string boundaries, there is no ...

Mockito is built for testing the unit, whereas Wiremock is built specifically for the integration testing. Mockito aids itself as “a mocking framework that tastes really great” whereas wiremock stimulates itself as “a simulator for HTTP-based APIs”. Both wiremock and mockito are the technologies used for testing that is widely used for unit and integration testing in natural world applications. Developers have to understand these two important terms and how they differ from each other to use them in an effective way. Therefore, we will cover the main difference between these two extensively used tools in this article. What ... Read More

In digital image processing, the auto cropping based labeling the connected components is a cropping technique in which different regions in an image are determined by using labeled connected component. After that the image is automatically cropped by extracting the surrounding area of each connecting component. The main advantage of the auto-cropping based on labeling the connected components is that it allows to isolate and extract individual regions of interest within an image. Algorithm The step-by-step process to execute the auto-cropping based on labeling the connected components is given below: Step 1 - Process the image if necessary. ... Read More

Histogram equalization is a method used in image processing to improve the dynamic range of the histogram. This mathematical technique is widely used for enhancing the contrast of an image in digital image processing. This technique provides a wider and balanced distribution of pixel values in the image. Histogram equalization technique basically works by enhancing the range of brightness values in the image which makes it more visually attractive. Introduction to Adaptive Histogram Equalization (AHE) In digital image processing, the adaptive histogram equalization (AHE) is a method used for enhancing the contrast of an image. The adaptive histogram equalization ... Read More

While working with JSON objects, Sometimes we need to delete an index or key from the JSON object to remove unwanted data or modify the structure. We can delete the index from a JSON object using methods like the delete operator, filter method, and lodash library. In this article, we will explore these different methods to delete an index from a JSON object. Prerequisites To follow along with the examples provided in this article, you should have a basic understanding of JavaScript and JSON syntax. Additionally, you will need a text editor or an integrated development environment (IDE) to write ... Read More

Debugging is an essential skill for developers to identify and resolve issues in their code. With the arrival of ES6 (ECMAScript 2015), JavaScript introduced several new features and syntax improvements. We can debug code in ES6 using various methods like Using Console Statements, Leveraging Debugging Tools, Employing Breakpoints, Analyzing Stack Traces, Debugging Asynchronous Code, and Advanced Debugging Techniques. This article will provide a detailed guide on how to effectively debug code in ES6. Setting Up a Development Environment Before we start debugging ES6 code, it's important to set up a suitable development environment. We can choose any code editor or ... Read More

jQuery is a popular JavaScript library that simplifies the process of traversing and manipulating HTML documents. In web development, one common requirement is to select elements with specific attributes or properties. In this article, we will explore how to select HTML elements whose IDs start with a certain character using jQuery. Use of Selecting ID that starts with certain character Targeting Specific Groups of Elements: When working with a large number of elements, it may be necessary to group them based on a common identifier. By selecting IDs that start with a specific character, you can easily target and ... Read More
