Add elements contained in list and map them to a string

Input

SomeName SomeFine

OtherName OtherFine

SomeOtherName SomeOtherFine

OtherName SomeOtherFine

SomeName OtherFine

Explanation

I want to make a List<Map<String, Integer>> so as to create a list of names and the total fines imposed upon them

Expected output

The output I'm expecting (with reference to the example above) is something like this:

[SomeName=SomeFine+OtherFine, OtherName=OtherFine+SomeOtherFine, SomeOtherName=SomeOtherFine]

Code

I tried using the following code, but it's giving me a ConcurrentModificationException. Here's the code:

public List<Map<String, Integer>> calculateTotalFine(){

        List<Map<String, Integer>> myMapList = new ArrayList<Map<String, Integer>>();

        ListIterator<CrimeInfo> crimeIterator = list.listIterator();
        while(crimeIterator.hasNext()){
            String key = crimeIterator.next().getName();
            Integer value = crimeIterator.next().getFine();

            if(myMapList.isEmpty()){
                Map<String, Integer> aMap = new HashMap<String, Integer>();
                aMap.put(key, value);
                myMapList.add(aMap);
            }

            else{
                Iterator<Map<String, Integer>> mapIterator = myMapList.iterator();
                while(mapIterator.hasNext()){
                    if(mapIterator.next().containsKey(key)){  //<-- Line no. 29
                        Integer newFine = mapIterator.next().get(key) + value;
                        mapIterator.remove();

                        Map<String, Integer> nMap = new HashMap<String, Integer>();
                        nMap.put(key, newFine);
                        myMapList.add(nMap);
                    }
                    else{
                        Map<String, Integer> newMap = new HashMap<String, Integer>();
                        newMap.put(key, value);
                        myMapList.add(newMap);
                    }
                }
            }
        }
        return myMapList;
    }

Actual output

Exception in thread "main" java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:901) at java.util.ArrayList$Itr.next(ArrayList.java:851) at com.company.CoreLogic.calculateTotalFine(CoreLogic.java:29)

Can someone tell me where I'm going wrong?
