  自我简介:

TA的其他文章

解题思路:

参考代码1并未在主函数中输出

参考代码2使用map集合来进行输出



注意事项:





参考代码:

参考代码1;

import java.util.Scanner;

public class Main {

        public static void cs(String a){

                char[] array = a.toCharArray();

                int Letter = 0;

                int Num = 0;

                int Space = 0;

                int Character = 0;

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

                        array[i] = a.charAt(i);

                        if(65<=array[i]&&array[i]<=90||97<=array[i]&&array[i]<=122)

                                Letter++;

                        else if(48<=array[i]&&array[i]<=57)

                                 Num++;

                        else if(array[i]==32)

                                 Space++;

                        else

                                 Character++;

                }

        System.out.print(Letter+" "+Num+" "+Space+" "+Character);

        }

        public static void main(String[] arg){

                Scanner sc = new Scanner(System.in);

                String a = sc.nextLine();

                cs(a);

        }

}

参考代码2;

import java.util.Scanner;

import java.util.HashMap;

import java.util.Map;


public class Main {

        public static Map<String, Integer> cs(String a){

                char[] array = a.toCharArray();

                Map<String, Integer> M = new HashMap<String, Integer>();

                int Letter = 0;

                int Num = 0;

                int Space = 0;

                int Character = 0;

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

                        array[i] = a.charAt(i);

                        if(65<=array[i]&&array[i]<=90||97<=array[i]&&array[i]<=122)

                                 Letter++;

                        else if(48<=array[i]&&array[i]<=57)

                                 Num++;

                        else if(array[i]==32)

                                 Space++;

                        else

                                 Character++;

                }

                M.put("Letter", Letter);

                M.put("Num", Num);

                M.put("Space", Space);

                M.put("Character", Character);

                return M;

        }

        public static void main(String[] arg){

                Scanner sc = new Scanner(System.in);

                String a = sc.nextLine();

                System.out.print(cs(a));

        }

}
