string类型转换List<string> 像List<String>lists=new List<String>; lists中有size属性，不要数组string
List<String> list = new ArrayList<String>(words.length);
for (String s : words) {
list.add(s);
}

是这样的吗，把字符串数组转成字符串集合
String[] words = {"a","b","c","d","e"};
List<String> list = Arrays.asList(words);
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
//顺便一说，定义list的时候你也可以不指定长度的，变长的，随时添加移除都行的
