ASCII和和元音检测 [英] ASCII sum and vowel detection

问题描述

我遇到了为A = 65，B = 66等实现ASCII的问题。我使用ASCII的其他代码使用随机方法，当我实现它只打印一些随机字母。很抱歉，如果这似乎只是试图让我的硬件完成而不尝试，那不仅仅是我会如何在while循环中执行ASCII值。



我尝试过：

I'm having issues with implementing the ASCII for things like A = 65, B = 66 and so on. My other code that uses the ASCII uses the random method and when I implement that it just prints some random letters. Sorry if this seems like I'm just trying to get my HW done without trying, thats not it just stuck with how I would do the ASCII values within a while loop.

What I have tried:

public static void main(String[] args) 
    {
       Scanner in = new Scanner(System.in);
        System.out.print("Input some text: ");
        String str = in.nextLine();
        
       int chr = 'A';
       int chr2 = 'E';
       int chr3 = 'I';
       int chr4 = 'O';
       int chr5 = 'U';
       boolean vowel = false;
       
       while(vowel)
       {
           if(chr == 'A' && chr2 == 'E' && chr3 == 'I' && chr4 == 'O' && chr5 == 'U')
           {
              System.out.println("A vowel was entered");
           }else
           {
               System.out.println("A vowel was not entered");
           }
       }
    }
}

推荐答案

嗯，你很远由于一系列原因，远远没有解决方案：

Well, you're far, far of solution due to set of reasons:

1. 元音集取决于语言（例如一组波兰元音是：{A ，Ą，E，Ę，....，O，Óa，ą，e，ę，... o，ó}等，
2. 元音可能是大写或小写。所以，你必须定义它：
   
   

1. A vowel set depends on language (for example a set of polish vowels is: {A, Ą, E, Ę, ...., O, Ó a, ą, e, ę, ... o, ó} etc.,
2. A vowel may be upper or lower case. So, you have to define it:
   

String vowels = "aeiouAEIOU";

您的，而循环什么都不做，我的意思是不要在输入的文本中搜索元音。

your while loop does nothing, i mean that do not searches vowels in entered text.
