Java集合(Java Collections)

 我将以下内容添加到UI表单中每行之后的HashMap集合中 
 
 宣言 
 
Map<String, List<String>> map = new HashMap<String, List<String>>();

List<String> valSetOne = new ArrayList<String>();
 
 代码段 
 
    valSetOne.add("BMW");
    valSetOne.add("Audi");
    map.put("A1", valSetOne);
 
 当我在UI的第二行时，我想检查HashMap集合中存在的上述组合。 
 
 我如何检查每一行中的值的组合？ 

I am adding the following to the HashMap collection after each row in the UI form
 
Declaration
 
Map<String, List<String>> map = new HashMap<String, List<String>>();

List<String> valSetOne = new ArrayList<String>();
 
Code snippet
 
    valSetOne.add("BMW");
    valSetOne.add("Audi");
    map.put("A1", valSetOne);
 
When I am in the second row in UI, I would like to check the above combination exist in the HashMap collection.
 
How can I check for the combination of values in each row?
