Question

如何将List<string>转化为string

Answer 1

调用这个方法
static String[] convert(List<String[]> from) {
ArrayList<String> list = new ArrayList<String>();
for (String[] strings : from) {
Collections.addAll(list, strings);
}
return list.toArray(new String[list.size()]);
}

或者是
String [] string = new String [List.size()] ;
List.toArray(string);
