Steps to Check Automorphic Number in Java. 12 + 92=82 The sum comes out to be 1. Make A Multiplication Table Using Java Program. The value 2n − σ(n) (or n − s(n)) is called the number's deficiency. Write a Java program to find all the narcissistic numbers between 1 and 1000. Expected Output. Write a Program in Java to check whether a number is a Keith Number or not. Deficient number: 7508 Input Data: The first few pronic numbers are: As an example, divisors of 21 are 1, 3 and 7, and their sum is 11. We have used a for loop that executes up to 100 times and for each iteration of i the if statement checks the number is even or not. Write a Java program to check if a number is palindrome or not. The first few Fermat numbers are: (With that iteration limit of 500). 1729 = 1^3 + 12^3 = 9^3 + 10^3 142857 × 6 = 857142 32832 = 4^3 + 32^3 = 18^3 + 30^3 142857 × 4 = 571428 Most of the time, while working with numbers in java, we use primitive data types.But, Java also provides various numeric wrapper sub classes under the abstract class Number present in java.lang package. Write a Java program to check a number is a cyclic or not. JavaTpoint offers college campus training on Core Java, Advance Java, .Net, Android, Hadoop, PHP, Web Technology and Python. A Lychrel number is a natural number that cannot form a palindrome through the iterative process of repeatedly reversing its digits and adding the resulting numbers. Go to the editor Happy number: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1, or it loops endlessly in a cycle which does not include 1. By convention, 1 is included. 0, 1, 2, 5, 12, 29, 70, 169, 408, 985, 2378, 5741, 13860,…. The first ten amicable pairs are: (220, 284), (1184, 1210), (2620, 2924), (5020, 5564), (6232, 6368), (10744, 10856), (12285, 14595), (17296, 18416), (63020, 76084), and (66928, 66992). Expected Output, 17. This is one of the important Java interview questions for fresher. Java Program to Check Whether a Number is Even or Odd. You can take a pdf of each program along with source codes & outputs. Go to the editorNote: A Duck number is a number which has zeroes present in it, but there should be no zero present in the beginning of the number. 46683 = 3^3 + 36^3 = 27^3 + 30^3 26. To understand how this line is reversing the number, let us add a few statements to print the value of digit and revNum at each iteration of the while loop. Write a Java program to check whether a given number is an ugly number. 142857 × 3 = 428571 Actually, the binary number consists of only 0 and 1. 142857 × 5 = 714285 * 10000 Go to the editorIn mathematics, the Pell numbers are an infinite sequence of integers. The sequence of Pell numbers starts with 0 and 1, and then each Pell number is the sum of twice the previous Pell number and the Pell number before that. 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, 240, 272, 306, 342, 380, 420, 462 … etc. Expected Output Write a Java program to display first 10 Fermat numbers. Go to the editor After printing each even number, the value if i is increased by 1. This process is sometimes called the 196-algorithm, after the most famous number associated with the process. The first four Mersenne primes are 3, 7, 31, and 127, 23. 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, … σ1(n) = 2n. 4104 = 2^3 + 16^3 = 9^3 + 15^3 The integer 12 is the first abundant number. Please mail your requirement at firstname.lastname@example.org. 1.2 Write a java program to reverse a String? An unhappy number is a number that is not happy. Go to the editor 1729 = 1^3 + 12^3 = 9^3 + 10^3 Therefore, while using a wrapper class you just need to pass the value of the primitive data … Let’s sum the digits again. Write a Java program to generate and show the first 15 narcissistic decimal numbers. The sequence of Lucas numbers is: 2, 1, 3, 4, 7, 11, 18, 29, …. In computer science, regular numbers are often called Hamming numbers, Hamming Numbers are numbers whose only prime factors are 2, 3 and 5. 50 Yor Guess is lower than the right guess!
