In number theory, a narcissistic number is a number that is the sum of its own digits each raised to the power of the number of digits. Here are some examples of Ramanujan numbers : ANALYSIS. So, now let's start this tutorial! Output: Guess a number between 1 to 100, You will have 10 turns! 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). The first few abundant numbers are: In order to check the number, we have divided the number by 2 if it does not leave any remainder, the number is even and the print statement prints that number. Go to the editor 1. Equivalently, the number 6 is equal to half the sum of all its positive divisors: ( 1 + 2 + 3 + 6 ) / 2 = 6. After printing each even number, the value if i is increased by 1. 153 = 13 + 53 + 33, 24. 12, 18, 20, 24, 30, 36, 40, 42, 48, 54, 56, 60, 66, 70, 72, 78, 80, 84, 88, 90, 96, 100, 102,… 142857 × 3 = 428571 Here we covered over the list of 500+ Java simple programs for beginners to advance, practice & understood how java programming works. Java String class, Java Number class are all examples of these wrapper classes which convert a primitive datatype to an object of the class. An Automorphic number is a number whose square ends with the same digits as the original number.E.g – 25, 76, 376 etc.. Steps to Check Automorphic Number in Java. Answer: An instance of Random class is used to generate a stream of pseudorandom numbers. The course is designed to give you a head start into Java programming and train you for both core and advanced Java concepts along with various Java frameworks like Hibernate & Spring. Run the above Java program, and you shall get the following output. 1882 is indeed a Magic Number. 1.6 Write a program to count number of words in a String? Go to the editor The value 2n − σ(n) (or n − s(n)) is called the number's deficiency. Please mail your requirement at hr@javatpoint.com. Test Data JavaTpoint offers too many high quality services.

This will be done using if...else statement and ternary operator in Java. The first few terms of the sequence are : For example 175 is a Disarium number : In arithmetic and algebra, the cube of a number n is its third power: the result of the number multiplied by itself twice: In this example, we shall use Java For Loop to find the factorial of a given number. Write java program to find any number between 1 and n that can be expressed as the sum of two cubes in two (or more) different ways. Using Inbuilt Method- toBinaryString() of the Integer class of Java; Approach 1: Using Implementation of Stack. Here in this article, we are going to talk about the Number class and its methods in Java programming. There are mainly six sub-classes under Number class.These sub-classes define some useful methods which are used frequently while dealing with numbers. The first few unhappy numbers are 2, 3, 4, 5, 6, 8, 9, 11, 12, 14, 15, 16, 17, 18, 20.

Armstrong (Michael F. Armstrong) number is a number that is equal to the sum of cubes of its digits. Java Program To Make Fibonacci Series With Explanation. Sum of the digits in third iteration for 10: 1 + 0 = 1. 4104 = 2^3 + 16^3 = 9^3 + 15^3 The sequence of Lucas numbers is: 2, 1, 3, 4, 7, 11, 18, 29, …. It is not an ugly number. Test Date:Input an integer number: 235 Similarly, 10 has two odd prime pairs, i.e. * 10000 In this article, we will learn to print the different Number pattern programs in Java. Go to the editor Make A Multiplication Table Using Java Program. Example: 6 = 3 + 3 10 = 3 + 7 10 = 5 + 5 Hence, 6 has one odd prime pair 3 and 3. 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. In this post I have taken some different number pattern programs in java and tried to solve them . 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. To learn the Java even number program, you must have the basic knowledge of Java for loop and if statement. 26. This process is sometimes called the 196-algorithm, after the most famous number associated with the process. 142857 × 5 = 714285 Write a Java program to check whether a given number is a happy number or unhappy number. σ1(n) = 2n. 1729 = 1^3 + 12^3 = 9^3 + 10^3 Write a program to accept an even integer ‘N’ where N > 9 and N < 50. Perfect number: 4 Write a Java program to check whether a number is a Pronic Number or Heteromecic Number or not. For example: Write a Java program to display first 10 lucus numbers. [crayon-6004c9d71379f746741040/] In … 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. The most widely known are 142857: Number 171 is a Harshad Number because the sum of digits 1 and 7 and 1 is 9(1+7+1) and 171 is divisible by 9. Write a Java program to check whether a number is a Harshad Number or not.

They are named after the Belgian mathematician Eugène Charles Catalan. There are three ways to reverse a number … 19 Different Number Pattern Programs in Java Java programs to print the numbers or any different pattern is one of the easiest ways to kick off your coding skills in java. Sum of its digits powered with their respective position is equal to the original number. Write a Java program to find and print the first 10 happy numbers. 82 + 22=68 Go to the editor A number will be called Disarium if the sum of its digits powered with their respective position is equal with the number itself. (i) input the ISBN code as a 10-digit number (ii) If the ISBN is not a 10-digit number, output the message “Illegal ISBN” and terminate the program (iii) If the number is 10-digit, extract the digits of the number and compute the sum as explained above. In our case, the range is 1 to 10. 62 + 82=100 1729 = 1^3 + 12^3 = 9^3 + 10^3 Expected Output : Input Data: Go to the editor Inside the method, we have used nested-if statement.

In case if you are looking out for C Programs… Input a number: 8 In computer science, regular numbers are often called Hamming numbers, Hamming Numbers are numbers whose only prime factors are 2, 3 and 5. The algorithm would be same as that of the one used in above example. Go to the editorCircular Prime : A circular prime is a prime number with the property that the number generated at each intermediate step when cyclically permuting its (base 10) digits will be prime. Because 11 is less than 21, the number 21 is deficient. 3 and 7, 5 and 5. The property is such that, when the number is multiplied by 2 and 3, and both these products are concatenated with the original number, all digits … In this program, you'll learn to check if a number entered by an user is even or odd. The java program to calculate average of three numbers has been written in five different ways such as Scanner class, direct value initialization, Buffered Reader class, Command Line argument, methods, and using Constructor. 2.
