Tried to write a logic to check whether the given number is armstrong number or not. Here I need a help. Though the values are same it always prints false and as per the logic it says the numbers are not equal.
package src;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class ArmStrongTest {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println(isArmStrongNumber(153));// prints false;
}
private static boolean isArmStrongNumber(int nos) {
List<Integer> digits = new ArrayList<Integer>();
int itrNumbers = 0;
while (nos > 0) {
digits.add(nos % 10);
nos /= 10;
}
Collections.reverse(digits);
for (int i : digits) {
itrNumbers += i * i * i;
}
System.out.println(java.util.Objects.equals(Integer.valueOf(itrNumbers), Integer.valueOf(nos)));// prints false;
if (itrNumbers == nos ) { // both values are 153 but it says not equals
return true;
} else {
return false;
}
}
}
How to solve this problem? Anything I missed in the code ? I am not able to figure out. I am getting false printed all the time. In such cases how to solve this problem?
