       String compare = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

       char []xx = compare.toCharArray();
       for(int i=0;i<compare.length();i++){
          if(arrs[0]==xx[i])

    }



    static Scanner con = new Scanner(System.in);
    public static void main(String...args){

       System.out.print("Enter a string: ");
       String str = con.next();
