如果我有一个包含多个字符串的数组，例如//1) if you can avoid using linked list use below solution
List<String> words= getWordsFromDB(); //words list has nearly 120k elements
//if you can avoid using linked list, use set instead
Set<String> set=new HashSet<>();
for (String s:words) {
if (!set.add(s)) {
//do some calculations
}
}
//2) if you can't avoid using linked list use below code
List<String> words= getWordsFromDB(); //words list has nearly 120k elements
List<String> tempList = new LinkedList<String>(); //empty list
//if you can't avoid LinkedListv (tempList) you need to use a set
Set<String> set=new HashSet<>();
for (String s:words) {
if (set.add(s)) {
tempList.add(s);
} else {
int a = tempList.indexOf(s);
//do some calculations
}
}
，lineItems.0.domain等，是否有更简单的方法来了解这些lineItems.1.domain中是否包含某些domains？< / p>
不确定如何将其全部合二为一，所以只需使用大量的$或语句
