我正在尝试制作一个程序来查找用户输入的字符串中的辅音、元音和非字母表

Question

import java.util.Scanner;
public class Chupapi{

static Scanner input = new Scanner(System.in);

public static void main(String[] args){

    String str = " ";
    int consonant = 0, vowel = 0, non_alpha = 0;
    System.out.print("Enter string: ");
    str = input.nextLine();

    consonant = getConsonantCount(str);
    vowel = getVowelCount(str);
    non_alpha = getNonAlphaCount(str);
  }

}

这是我的代码，我做的方式对吗？我有点纠结于用什么来倒数辅音、元音和非字母表。

因此，您基本上需要运行for循环，检查当前字符是元音、辅音还是非字母字符。

public static void main(String[] args) throws Exception {
        
        Scanner sc = new Scanner(System.in);
        String str = sc.next();
        StringBuffer cosonantSb = new StringBuffer();
        StringBuffer vowelSb = new StringBuffer();
        StringBuffer noAlphabetSb = new StringBuffer();
        for(int idx = 0 ; idx < str.length() ;idx++) {
            char currentChar = str.charAt(idx);
            if( Character.toUpperCase(currentChar) == 'A'  ||
                Character.toUpperCase(currentChar) =='E'  ||
                Character.toUpperCase(currentChar) == 'O' || 
                Character.toUpperCase(currentChar) == 'I' ||
                Character.toUpperCase(currentChar) == 'U' ) {
                vowelSb.append(currentChar);
              }
            else if(Character.toUpperCase(currentChar) >= 'A' &&
                    Character.toUpperCase(currentChar) <= 'Z') {
                cosonantSb.append(currentChar);
            }
            else {
                noAlphabetSb.append(currentChar);
             }
        }
        System.out.println("Consonants :"+cosonantSb);
        System.out.println("Vowels :"+vowelSb);
        System.out.println("Non Aplhabets : "+noAlphabetSb);
        
    } 

输出：

scbalcb1232434knclnsd]12
Consonants :scblcbknclnsd
Vowels :a
Non Aplhabets : 1232434]12
