Write a java program to generate the armstrong number

By the way this program has different variations as well e. This function returns a double value which we explicitly cast to an int so that we can add it to the existing sum.

We first find the number of digits in the input number. So, precisely this is a program to display thee digit Armstrong number between 0 to or any user supplied upper range.

how to write a program in Armstrong number in 1 to 1000

To do so, we construct a String by concatenating the input number with a null string. Along with usual beginner exercises e.

It is required that we make a copy because the number to be checked will be changed during the execution of the program and towards the end, we need the original input number to declare whether it is an Armstrong number or not. We can also use the valueOf int method of the String class.

The remainder is raised to the power numberOfDigits using the Math. Extract individual digits of number in each iteration Calculate cube of that digit and add into sum which is initialized with zero reduce the number by factor of 10 to remove one digit.

The while loop executes as long as copyOfInput is not zero. The length of the resultant string obtaining using the length method will give us the number of digits in the input number. It repeats this process until input is not zero, which is our base case to stop checking.

Now, the last digit of copyOfInpuit will be truncated by diving it with Finally, we check if sum equals the input number. Apart from this, I would recommend following programs to any Java beginners: Next, in a while loop, we extract the digits of the input from right to left, raise them to the appropriate power and add to the existing value of sum.

So a four digit Armstrong number will be equal to sum of power four of individual digits of that number.

C Program to Generate Armstrong Numbers

Logic is simple but presents a powerful technique to solve any problem which is based in individual digit of number. Write a Program to Find all Armstrong number in the range of 0 and - Example An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.

Well, for that you need to remember general definition of Armstrong number which is, An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits. This is again called in a loop to supply all the numbers from 0 to We represent the number as nxnx-1nx Core logic of checking if a number is Armstrong or not is same, but you need to tweak them little bit to solve these programming problems.

This logic is encapsulated inside a private static method called isArmstrongNumber int number. To be more clear, let the number be n and the number of digits be x.

Though it has one shortcoming, logic of checking if number is Armstrong or not is hard-coded to find only three digit numbers. So if user wants to see Armstrong number between 0 andhe should enter We also declare a variable sum and initialise it to zero.

At the end of this loop if calculated sum is equal to original number, then its an Armstrong other wise its not. Given below is the complete code for this program. Coming back to logic, all it does is: When it is zero, all the digits would have been processed. As I said this program is very popular coding exercise for Java beginners and there are lot of versions exists e.

Our solution is simple but general, we have a loop which runs up-to a number entered by user.C program to Display Armstrong Number Between Intervals.
