public class Main {
 
 public static void main(String[] args) {
        String test = "@sateeshm.com 123456";
       
        char[] ch = test.toCharArray();
        int letter = 0;
        int space = 0;
        int num = 0;
        int otherchat = 0;
        for(int i = 0; i < test.length(); i++){
            if(Character.isLetter(ch[i])){
                letter ++ ;
            }
