How to find Armstrong number using Java

An Armstrong number (also known as a narcissistic number, pluperfect digital invariant, or pluperfect number) is a number that is the sum of its own digits each raised to the power of the number of digits. In other words, an n-digit number is an Armstrong number if the sum of its digits, each raised to the power of n, is equal to the number itself. For example, let's consider a 3-digit number like 153: 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153 Since the sum is equal to the original number, 153 is an Armstrong number. Here are a few more examples: 1634 is an Armstrong number because 1^4 + 6^4 + 3^4 + 4^4 = 1634. 9474 is an Armstrong number because 9^4 + 4^4 + 7^4 + 4^4 = 9474. Armstrong numbers are named after Michael F. Armstrong, who first introduced them in a 1938 publication. These numbers are interesting mathematical curiosities and are often used as programming exercises. package logical ; import java . util . * ; public class Armstrong { public static void m...

How to Declare and Initialize One Dimensional Array in Java

One-dimensional arrays in Java are arrays that contain only one dimension. In other words, they can store elements but cannot be used to store other arrays. To declare a one-dimensional array in Java, you need to specify the type of the elements and the number of elements in the array. Here's the general syntax for declaring a one-dimensional array: package array ; import java . util . * ; public class OneD { public static void main ( String [] args ) { Scanner sc = new Scanner ( System .in); System .out. println ( "Enter the digit number:" ); int n = sc. nextInt (); int num[] = new int [n]; System .out. println ( "Enter numbers :" ); for ( int i = 0 ; i < n; i ++ ) { num[i] = sc. nextInt (); } ...

How to Use Lambda Function in Java

Java, the language that powers a significant chunk of the digital world, has undergone transformations to make coding more intuitive and efficient. One of the game-changers introduced in Java 8 is lambda functions—a feature that allows developers to craft concise and expressive code. In this blog post, we'll delve into the world of lambda functions, demystify their usage, and explore how they can elevate your Java programming experience. Unlocking the Lambda Secret: Lambda functions, often referred to as anonymous functions or closures, provide a streamlined way to express instances of single-method interfaces, also known as functional interfaces. These lightweight and versatile constructs have become a favorite among Java developers for their ability to simplify code. Let's dive into how to define a lambda function. Navigating the Landscape of Functional Interfaces: Lambda functions seamlessly integrate with functional interfaces, which are interfaces with only one abstrac...

How to use Ternary Operators in Java

The ternary operator in Java is a shorthand way to express an if-else statement. It's a compact form of writing conditional expressions. The syntax of the ternary operator is: result = (condition) ? value1 : value2; Condition: (condition): This is a boolean expression or a condition that evaluates to either true or false. It's placed inside parentheses. Question Mark ?: The question mark ? is part of the ternary syntax, and it serves as a separator between the condition and the values. Value if True: value1: If the condition is true, the value assigned to the variable is value1. Colon :: The colon : separates the two possible outcomes in the ternary expression. Value if False: value2: If the condition is false, the value assigned to the variable is value2. example : package logical ; public class Ternary { public static void main ( String [] args ) { int j = 2 ; int i = 0 ; ...
