随机生成字母, 推断是元音字母还是辅音字母.
[0,26) + 偏移量’a’就能够生成小写字母.
代码:
//: Main.java
import java.util.Random;
/**
* 推断元音辅音
*/
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");
}
}
}
}
/**
