Replace copy with iteration with a constructor call

Before :

Map<String,String> a = new Hashmap<>();
a.add("hello","world");

Map<String,String> b = new HashMap<>();

for (Map.Entry<String, String> s : a.entrySet()){
 b.put(s.getKey(),s.getValue());
 }


// Lists
List<Integer> l1 = new ArrayList<>();
l1.add(1);

List<Integer> l2  = new ArrayList<>();

for (Integer i : l1){
l2.add(i);
}

After :

Map<String,String> a = new Hashmap<>();
a.add("hello","world");
Map<String, String> b = new HashMap<>(a);

// Lists
List<Integer> l1 = new ArrayList<>();
l1.add(1);

List<Integer> l2  = new ArrayList<>(l1);

Start by reviewing the Java before-and-after examples in the issue and locating the corresponding static-analysis recipe in this repository. Done means the map and list copy loops shown in the issue are identified as replaceable by collection-constructor calls, with coverage for the demonstrated forms.
