完整程式碼如下：
import java.nio.*;
import java.util.*;
public class RandomWords implements Readable
{
private static Random rand = new Random(47);
private static final char[] capitals =
"ABCDEFGHIJKLMNOPQRSTUVWXYZ".toCharArray();
private static final char[] lowers =
"abcdefghijklmnopqrstuvwxyz".toCharArray();
private static final char[] vowels =
"aeiou".toCharArray();
private int count;
public RandomWords(int count) { this.count = count; }
public int read(CharBuffer cb)
{
if(count

s.next() -> n = source.read(buf); source就是RandomWord

感謝，我去找code來看
