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
A string is a sequence of characters, including alphabets, numbers, and symbols. In this tutorial, we are going to learn how we can count the number of vowels in a given string in PHP using different approaches. Vowels in English are a, e, i, o, u, and they can be either uppercase or lowercase. What is a Vowel? Vowels are alphabetic characters that represent specific speech sounds.There are a total of five vowels, both uppercase and lowercase in the English language: a, e, i, o, u Example 1 Input: string = "Tutoriaspoint" ...

A square is a closed two-dimensional figure having 4 equal sides. Each angle of a square is 90 degrees. The perimeter of a square is the sum of all its sides. Problem Description In this problem, we are given the side of a square, and we have to find the perimeter of the square. In this tutorial, we are going to find the perimeter of a given square in Python using different approaches. Example 1 Input: side = 6 units Output: 24 units Explanation Using the formula to calculate ... Read More
Both compilers and assemblers are the language processors used to convert software codes written in high-level language and assembly language into machine language codes. Compiler and assemblers are the types of system software. These are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. and assembly language. Therefore, it is necessary to convert an HLL or assembly code into machine code for execution. In this article, we will highlight all the key differences between compilers and assemblers. Let's start with some basics of compiler and assembler so that it will ... Read More
Let's begin this article with a basic question. What do you mean by Language Translator? You may imagine a tool or piece of software that can translate between languages as needed so that both parties can understand. You are totally correct. Compilers and interpreters are simply language translators in computer programming. These are the software programs/tools that translate the source code of a programming language into machine code, bytecode, or any other intermediate code. Or, to put it simply, it transforms code from High Level Language to Low Level Language, making it machine understandable code. Every programmer is aware that interpreter ... Read More
