In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example: 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number.
Program:-
package payilagam.institution;
public class Amstrong {
public static void main(String[] args) {
int num = 370, temp, total = 0 ;
int number=num;
while (num > 0)
{
temp = num % 10;
total = total + temp*temp*temp;
num= num/10;
}
System.out.println(total);
if(number==total)
{
System.out.println( "is an Armstrong number"); }
else
{
System.out.println( " is not an Armstrong number");
}
}
}
