如何计算元音和辅音，并在使用方法和返回结果输出时将字符串中的第一个字母大写 [英] How to count vowels and consonants and capitalizing first letter in a string while output using a method and return result

问题描述

如果用户输入字符串：你好

If a user enters a string: hello there

它应输出

Hello has 2 vowels
There has 3 consonants.

我知道这是一个相当简单的代码，但我得到的想法太多而且很困惑。
我需要一个确保我有2个方法来获取numberofVowels和capitalizeWord并且都返回结果

I know this is a fairly simple code but I am getting too many ideas and getting confused. I need a to make sure I have 2 methods for numberofVowels and capitalizeWord and both returns a result

我收到错误，我仍然想弄图在我计算元音后工作

I am getting an error and I am still trying to figure out to capitalize after I got counting vowels work

import java.util.Scanner;

public class Hwk9
{
        public static void main (String args[]) 
        {
                Scanner stdin = new Scanner(System.in);
                String string1;
                System.out.println("Enter a string");
                string1 = stdin.nextLine();
                string1 = string1.toLowerCase();

        }
        public static int numberVowels(String string1)
        {

                int count = 0;
                int vowels = 0;
                int consonants = 0;
                for (int i = 0; i < string1.length(); i++)
                {
                        char ch = string1.charAt(i);
                        if (ch == 'a' || ch == 'e' || ch == 'i' || 
                                        ch == 'o' || ch == 'u')
                        {
                                vowels++;
                        }
                        else
                        { 
                                consonants++;
                        }
                }
        }
}

推荐答案

这是一种更简单的方法，希望这会有所帮助：

Here is a simpler way of doing this, hope this helps:

public static void checkVowels(String s){
    System.out.println("Vowel Count: " + (s.length() - s.toLowerCase().replaceAll("a|e|i|o|u|", "").length()));
    //Also eliminating spaces, if any for the consonant count
    System.out.println("Consonant Count: " + (s.toLowerCase().replaceAll("a|e|i|o| |u", "").length()));
}
