  11. int temp = number;
  12. digit1 = temp % 10;
  13.  
  14. temp = temp / 10;
  15. digit2 = temp % 10;
  16.  
  17. temp = temp / 10;
  18. digit3 = temp % 10;
  19.  
  20. if(digit1*digit1*digit1 + digit2*digit2*digit2 + digit3*digit3*digit3 == number)
  21. {
  22. System.out.println(number);
  23. }
  24. }
