好吧，所以我只是一个简单的菜鸟，试图在已有的代码上加上我自己的小麻烦。唯一的问题是我需要将.java文件转换为.class。我在使用eclipse时遇到了困难，因为我需要某些软件包以使一切正常工作，但是当我将软件包放在那里时，它就不会构建一般。所以我放弃了eclipse并尝试了javac命令提示符。当我尝试它时，它给了我这个对我没有意义的错误，我只是愚蠢还是javac无法正常工作？
导致错误的原因是：
EnumPokemon.java:36: error: illegal start of expression
for (EnumPokemon pokemon : ) {
^
EnumPokemon.java:46: error: illegal start of expression
for (EnumPokemon e : ) {
^
EnumPokemon.java:71: error: illegal start of expression
for (EnumPokemon e : ) {
^
EnumPokemon.java:97: error: illegal start of expression
for (EnumPokemon pokemon : ) {
如果有人可以帮助像我这样的简单的菜鸟，那将非常感激！
编辑：感谢您推荐编辑，我是java和本网站的新手，所以我不知道该怎么做。我会复制并粘贴代码RN

答案 0 :(得分：1)
以下代码在无效的Java代码中。您缺少for-loop应该迭代的迭代器。
for (EnumPokemon pokemon : ) {
...
}
我假设您希望迭代EnumPokemon的值，您的代码应如下所示。
for (EnumPokemon pokemon : EnumPokemon.values()) {
...
}
