如何在Java中检查一个数字是否为Tech数？

public class Main {
   public static void main(String[] args) {

      temp = inputNumber;

      //find the number of digits available in input number
      while (temp > 0) {
         count++;
         temp = temp / 10;
      }

      
      //check whether the number of digits is ever or not
      
      //if even number of digits are present then proceed to check Tech number
      if (count % 2 == 0) {
         temp = inputNumber;
