int num = 9474, realNumber, remainder, output = 0, a = 0;
realNumber = num;
for(;realNumber != 0; realNumber /= 10, ++a);
realNumber = num;
for(;realNumber != 0; realNumber /= 10)
{
remainder = realNumber % 10;
output += Math.pow(remainder, a);
}
if(output == num)
{
System.out.println(num + " is an Armstrong number.");
