MultiValueMap in java

You don't have to do a split. This is the documentation of MultiMap that is found:

MultiMap mhm = new MultiHashMap();
 mhm.put(key, "A");
 mhm.put(key, "B");
 mhm.put(key, "C");
 Collection coll = (Collection) mhm.get(key);

Now when you do a get() call on a multimap, it gives you a collection. The first item will be your b and the second one will be your c.

You can try following :

String a, b, c;

MultiMap mMap = new MultiValueMap();
mMap.put("a", "Hello there, It's a wonderful day");
mMap.put("a", "nice to meet you");

Set<String> keys = mMap.keySet();

for (String key : keys) {
    System.out.println("Key = " + key);
    System.out.println("Values = " + mMap.get(key));
    List<String> list = (List<String>) mMap.get(key);

    b = list.get(0);
    c = list.get(1);
    System.out.println("B : " + b);
    System.out.println("C : " + c);
}
