Java - 判断元音辅音

随机生成字母, 判断是元音字母还是辅音字母.
[0,26) + 偏移量’a’就可以生成小写字母.

代码:

//: Main.java

import java.util.Random;

/**
 *  判断元音辅音
 */
class Main {
    public static void main(String[] args) {
        Random rand = new Random(47);
        for (int i=0; i<10; i++) {
            int c = rand.nextInt(26) + ‘a‘;
            System.out.println((char)c + ", " + c + ": ");
            switch (c) {
                case ‘a‘:
                case ‘e‘:
                case ‘i‘:
                case ‘o‘:
                case ‘u‘:
                    System.out.println("vowel");
                    break;
                case ‘y‘:
                case ‘w‘:
                    System.out.println("Sometimes a vowel");
                    break;
                default:
                    System.out.println("consonant");
            }
        }
    }
}
