JavaScript Object Notation or JSON is recognized widely for data interchange while exporting and importing modular result data is done through CSV (Comma-Separated Values). It is quite common to convert JSON to any other format for reporting purposes or to integrate with different systems. In this article, we will explore different ways to transform JSON data into CSV format in JavaScript, incorporating its code, examples, and clarifications of its principles. Understanding JSON and CSV Formats JSON: JSON represents data as an array of objects, with each object containing key-value pairs. ... Read More
CSV (comma-separated values) file formats are perfect for many applications that store tabular data while JSON (JavaScript Object Notation) is popular among web applications. Because it is understandable and cooperating with javascript is a lot of work transforming the data from CSV into JSON format. specifically, for the case of working with data within JavaScript, different techniques are sought in this article. Converting CSV files to JSON format in JavaScript with syntax, explanation of some examples, and the code. Understanding CSV and JSON Formats CSV: Saving data in rows separated by commas made CSV ...

Tailwind CSS is a utility-first CSS framework that helps to simplify the styling process by using an enormous number of pre-defined classes that can be applied directly in HTML. However, when using it with Angular component SCSS files, sometimes issues occur, especially since Tailwind CSS is not designed to be imported into individual component styles by default. This article addresses key issues as to why Tailwind CSS doesn't work as it would in an Angular component SCSS file and proposes ways around the problems that can come with it. Table of Content There could be multiple reasons why Tailwind CSS ... Read More
In this article, we will learn how to find the number in an array that appears an odd number of times using Java. By looping through the array and counting occurrences of each number, the program will detect and return the one with an odd frequency. Problem Statement Given an array identify the integer that occurs an odd number of times. Below is the demostration of the same − Input 34, 56, 99, 34, 55, 99, 90, 11, 12, 11, 11, 34 Output The number that occurs odd number of times in the array is 34 Steps to find the number occurring ...

In this article, we will learn how to remove a specific key from a HashMap in Java. By doing this, we can dynamically update the contents of the map, which is helpful in many data manipulation scenarios. We will demonstrate two different approaches: one that uses the straightforward remove() method to delete a specific key, and another that leverages an iterator to find and remove the key based on a condition while iterating. Each approach allows us to efficiently manage data in HashMap based on different requirements. Problem Statement Given a HashMap with key-value pairs, write Java programs to ... Read More
In this article, we will learn the procedures for sorting a HashMap in Java by its keys and values, as well as examine the performance implications associated with each technique. HashMap, a frequently employed data structure, enables programmers to store key-value pairs. This data structure is an exceedingly efficient method for storing data and allows for swift value retrieval based on keys. However, on occasion, it may become necessary to arrange the HashMap by its keys or values. Different Approaches of Sorting the HashMap Following are the different approaches to sorting a HashMap by Keys and Values − ... Read More
In this article, we will learn how to format date and time in Java using the Formatter and Calendar classes. The Formatter class allows for flexible string formatting, and the Calendar class is useful for retrieving and manipulating date and time values. We will use these classes to display the current hour, minute, and AM/PM marker. Problem StatementGiven a Calendar instance, write a Java program to display the current hour, minute, and AM/PM marker using the Formatter class.Input The program fetches the current date and time using the Calendar class.Output Current date and time: Mon Nov 26 07:41:35 UTC 2018 ...

In this article, we will learn how to set major tick marks in a JSlider component in Java. A JSlider is a Swing component that allows users to select a numeric value from a range. Tick marks help improve user experience by marking specific intervals along the slider. Major tick marks represent larger intervals, and we can control their spacing using the setMajorTickSpacing() method. Problem StatementGiven a slider with a range of values, write a Java program to set major tick marks every 25 units in a JSlider and display the slider in a GUI window.Input A slider with a range ...

In this article, we will understand how to remove all whitespaces from a string in Java. The String class in Java represents a sequence of characters enclosed in double-quotes. Removing whitespaces from a string is a common operation, especially when processing user input or cleaning data. The replaceAll() method is used with a regular expression to match whitespace characters and replace them with an empty string. Problem StatementGiven a string with whitespaces, write a Java program to remove all whitespaces from the string.Input Initial String = "Java programming is fun to learn."Output String after removing white spaces = ...
