How to iterate Map in Java

Map<Integer, String> map = new HashMap<>();
map.put(1,"Argentina");
map.put(2,"France");
map.put(3,"Brazil");
map.put(4,"Germany");

//EntrySet Iterator
System.out.println("\nEntrySet foreach");
Iterator<Entry<Integer, String>> it = map.entrySet().iterator();
while(it.hasNext()) {
    Map.Entry<Integer, String> keyVal = it.next();
    System.out.println(keyVal.getKey() + " " + keyVal.getValue());
}

//EntrySet and foreach
System.out.println("\nEntrySet foreach");
Set<Entry<Integer, String>> entrySet = map.entrySet();
entrySet.forEach((e-> { System.out.println(e.getKey() + " " + e.getValue());}));

//Keyset Iterator
System.out.println("\nKeyset Iterator");
Iterator<Integer> kit = map.keySet().iterator();
while(kit.hasNext()) {
    Integer key = kit.next();
	System.out.println(key + " " + map.get(key));
}

//Keyset For loop
System.out.println("\nKeyset For loop");
for (Integer key : map.keySet()) {
	System.out.println(key + " " + map.get(key));
}

//map foreach (Java 8 Lambda)
System.out.println("\nUsing Map.foreach (Java 8 Lambda");
map.forEach((key,value)-> {System.out.println(key + " " + value);});
