我正在使用 Java (NetBeans 6.8) 制作字谜游戏。代码运行时没有错误，但是当我尝试游戏时，我没有从 list/anagramlist 收到任何值（它返回“错误 - 空结果”）。我的代码有问题吗？我认为它可能在 WordList.java 中，因为这应该将值添加到列表中。也许我错误地称呼虚空？
注意：这是我的代码片段的汇编
这是我的代码：
//This is the code to add the word to the word list, and make the anagram
//and add it to the anagram list. This code is in the game creator
//(GameCreator.java)
String toadd = (jTextField1.getText() + ",");
WordList wordlist = new WordList();
AnagramMaker anagmaker = new AnagramMaker();
wordlist.addword(toadd);
wordlist.addanag(anagmaker.makeanagram(toadd, toadd.length()));
//This is the code in the anagram maker (AnagramMaker.java) to make the anagram
char[] usedpos;
public String makeanagram(String toanagram, int length){
usedpos = null;
String anagram = "";
Random rnd = new Random();
if(usedpos == null)
{
int rnum = rnd.nextInt(length);
usedpos = (Integer.toString(rnum)).toCharArray();
anagram += Character.toString(toanagram.toCharArray()[rnum]);
}
else
{
for(int i = 0; i < length; ++i)
{
int rnum = rnd.nextInt(length);
for(int pos = 0; pos < usedpos.length; ++pos)
{
if(Character.toString(usedpos[pos]).equals(Integer.toString(rnum)))
{
i-= 1;

}

pos = 0;
