In this article, we will learn to extract every nth element from an array and display a fixed number of values in Javascript. The objective is to filter out every second element (or more generally every nth element) from an array and limit the result to a specified count of elements. We will explore different approaches in JavaScript for achieving this functionality, each offering a unique way to solve the problem. Problem Statement Let's say you have an array that takes every nth element. Display a fixed number of values after extracting the elements. Input Let’s say the following is ... Read More

The Java threads provide a mechanism for the concurrent execution making it easier to perform the tasks in parallel. Often, we may need to pass parameters to a thread to ensure it operates with the specific input data. This article offers several practical approaches to passing parameters to a Java thread. Also read: How to create a Java Thread? Passing a Parameter to a Java Thread There can be multiple ways to pass a parameter to a Java thread; here are some of the ways you can use: Using a Custom Runnable Implementation ... Read More
In Java, converting a byte array to a string means transforming the raw binary data (byte array) into a human-readable text format (String). To convert a byte array to a string, we can use the String constructor and a specified character encoding, such as UTF-8. Byte Array: A byte array is a sequence of bytes, each byte being an 8-bit value. String: A string is a sequence of characters, representing text. Converting a Byte array to a String in Java is quite easy. Let us learn the following methods: ... Read More
In this article, we will learn to check if a number is Narcissistic in JavaScript. A Narcissistic number is a number that equals the sum of its digits, each raised to the power of the total number of digits. We will explore two approaches to solve this problem an iterative method and a concise string manipulation technique. Narcissistic number A narcissistic number(also known as an Armstrong number) in a given number base b is a number that is the sum of its digits each raised to the power of the number of digits. For example − 153 = 1^3 + ... Read More
In this article, we will learn to use DateFormat.LONG to format dates in Java. Handling dates and times efficiently is crucial for most applications. The Java Date and DateFormat classes provide a flexible and simple way to format dates and times. What is DateFormat.LONG? DateFormat.LONG is a constant provided by the DateFormat class in Java. It represents a predefined style for formatting dates in a long, readable format. When you use DateFormat.LONG, Java will format the date in a verbose format, typically displaying the day, month, and year in a comprehensive, localized form.DateFormat.LONG is a constant for long-style patterns. For ... Read More
In this article, we will learn to enable cell selection in a JTable in Java Swing. By default, JTable allows row or column selection, but enabling cell selection gives users the ability to select individual cells. This feature is useful for tasks that require precise control over table data, such as editing or copying specific values. Approach for Enabling Cell Selection in JTableThe goal is to create a JTable where users can select individual cells, rather than just rows or columns. The approach focuses on: Creating the JTable: We define a table with data ... Read More
A rectangle is a closed two-dimensional figure having 4 sides. The opposite sides are equal and parallel. The angle made by the adjacent side is equal to 90 degrees. The perimeter is the sum of all sides; in other words, the perimeter is two times the sum of length and breadth. In this tutorial, we are going to learn how we can find the perimeter of a given rectangle in Python using different approaches. Formula of Perimeter of Rectangle The formula for the perimeter of a rectangle is as follows: Perimeter of Rectangle = 2 × (length + breadth) ... Read More
What is Capsule and Its Volume? A capsule is a three-dimensional geometric figure that consists of a cylindrical body with hemispherical ends on both sides. The volume of a capsule can be calculated by adding the volume of the cylindrical part and the volume of the two hemispherical ends present on both sides of the cylindrical part. In this tutorial, we are going to discuss how to find the volume of a given capsule in Python using different approaches. Formula for Volume of Capsule The formula for the volume of a capsule is as follows: Volume of Capsule = ... Read More
