Armstrong Number in Java Program. An Armstrong three-digit number is an integer in which the total of its digits’ cubes equals the number itself. Because of the way the number behaves in a specific number base, it is of particular interest to beginning programmers and those learning a new programming language. Armstrong number for beginners to understand the concept of armstrong number from maths and programming for freshers.

class Main

{

public static void main(String[] args)

{

int low = 999, high = 99999;

for(int number = low + 1; number < high; ++number)

{

int digits = 0;

int result = 0;

int actualnumber = number;

while (actualnumber != 0)

{

actualnumber /= 10;

++digits;

}

actualnumber = number;

while (actualnumber != 0)

{

int remainder = actualnumber % 10;

result += Math.pow(remainder, digits);

actualnumber /= 10;

}

if (result == number)

{

System.out.print(number + " ");

}

}

}

}

Output:

1634 8208 9474 54748 92727 93084

## Armstrong Number in Java Program Using Pow

pow() is a function that raises a number to the power of another. This function takes two arguments and returns the first parameter’s value multiplied by the second. The value of the first integer raised to the power of the second number is returned by math. pow(double a double b), and you must do the same. To put it another way, you must develop a Java function to calculate the power of integer numbers. Armstrong number in java for freshers.

## What is Pre Increment in Java Program

The value of the first integer raised to the power of the second number is returned by math. pow(double a double b), and you must do the same. To put it another way, you must develop a Java function to calculate the power of integer numbers.

After utilising a variable in an expression, the post increment operator is used to increase its value. The value is used inside the expression and then incremented by one in the post increment.

## What is While Loop and How to Execute

The while loop in Java is a control flow statement that allows code to be repeated based on a Boolean condition. The while loop is similar to a looping if statement. If the condition evaluates to true, the body of the loop will be executed, and we will proceed to the update expression. Armstrong number in java using while loop for freshers.
