解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

        Scanner scanner=new Scanner(System.in);

        String zifu=scanner.nextLine();

        int a=0,b=0,c=0,d=0;

        for(int i=0;i<zifu.length();i++){

                if(zifu.charAt(i)>='A' && zifu.charAt(i)<='Z'||zifu.charAt(i)>='a' && zifu.charAt(i)<='z'){

                    a++;

                }else if(zifu.charAt(i)>='1' && zifu.charAt(i)<='9'){

                    b++;

                }else if(zifu.charAt(i)==' '){

                    c++;

                }else{

                    d++;

                }

            } 

    System.out.print(a+" "+b+" "+c+" "+d);

}

}
