Why can't we replace a character with empty character. I want to remove spaces from sentence and using ch = str.charAt(i); str = str.replace( ch , ""); but it is showing error

Why it is not working. It is a program for Duck Number import java.util.Scanner; public class magic { public static void main (String args[]) { Scanner sc = new Scanner(System.in); System.out.println("ENTER NO TO CHECK"); int num = sc.nextInt(); String str = Integer.toString(num); int len = str.length(); int count = 0; int i; for(i=0 ; i <len ; i++) { if ( str.charAt(i) == '0') count ++; } if(count > 0 && str.charAt(0) != '0') System.out.println("It is a Duck Number"); else System.out.println("It is not a Duck Number"); } }

If there is difference between two things asked for 2 marks and we have only one point are examples accepted?
