Count the number of capital letters

Import Java.util.scanner;public class main{public static void Main (String[]args) {Scanner Scanner = new Scanner (system.in ); String S=scanner.nextline (), if (S.isempty ()) {System.out.println (0);} Else{int no=0;for (int i = 0; i < s.length (); i++) {if (S.charat (i) >=65 && s.charat (i) <=90) {no++;}} System.out.println (No);}}}

There is another way, personally, that no problem, but in

The OJ is wrong.

Import Java.util.scanner;public class Getuppercasenum {/** *  * Find the number of uppercase characters (that is, ' A '-' Z ') in a given string */public static void main ( String[] args) {Scanner scan = new Scanner (system.in); String num = Scan.nextline (), int count = 0;if (Num.isempty ()) System.out.println (0); char[] ch = num.tochararray (); for ( Char c:ch) {if (Character.isuppercase (c)) count++;} System.out.println (count);}}
