问题：

Consider: 考虑：

List<String> someList = new ArrayList<String>();
// add "monkey", "donkey", "skeleton key" to someList


for (String item : someList) {
    System.out.println(item);
}

What would the equivalent for loop look like without using the for each syntax? 如果不对_每种_语法使用_for_ ，等效的for循环会是什么样？
