找出给定字符串中大写字符(即'A'-'Z')的个数。

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    while (scanner.hasNextLine()) {
        String nextLine = scanner.nextLine();
        int count = 0;
        for (int i = 0; i < nextLine.length(); i++) {
            if (Character.isUpperCase(nextLine.charAt(i))) {
                count++;
            }
        }
        System.out.println(count);
    }
}

}
