For a project, I have to create a map where the keys are List
s of String
and the value is two integers. So, I made it like this:
private Map<LinkedList<String>, int[]> playerProfile;
private List<String> previousChoices;
Then later I have to iterate through the map and write all the key-value combinations to a data file. So I am setting up an iterator like this:
Set<Entry<LinkedList<String>, int[]>> profileSet;
profileSet = playerProfile.entrySet();
//iterate through the Set
List<String> curList; //current list of choices
int[] curHeadTail; //current list of heads/tails
Entry<LinkedList<String>, int[]> curEntry;
Iterator<Entry<LinkedList<String>, int[]>> i =
profileSet.iterator();
What I want to know is: is there a simpler way to do this that takes less lines of code? And at one point I have triply-nested generics. Is that too much?
Sure, you can use a for-each loop:
for(Entry<LinkedList<String>, int[]> curEntry : playerProfile.entrySet()){
// now you can use curEntry
}
And no, nested generics here (and in general) are not a problem.
