[solved]Implementation with multiple values for each key?

Is there a Collection Implementation which can store multiple values for a single key? (It doesn't matter what the key is or how it is assigned.)

 

Create a new class that stores all the values, then use a normal Map.

 

how about:

Code:

Map<String, List<Object>> multipleValuesForSingleKey;

?

 

how do I get the information that are in the lists?

 

depending if you just want to store values and iterate through them or if they should have a key themselves.

Code:

for(Object listObject : multipleValuesForSingleKey.get(keyForList))
{
  // do whatever with the object...
}

otherwise you could do that:

Code:

Map<String, Map<String, String>> multipleValuesForSingleKeyWithSubKeys;

but thats not really efficient. Another way would be the one nisovin mentioned.
