System.out.println(entry.getKey() + " = " + entry.getValue());
}
map.forEach((k, v) -> {
System.out.format("key: %s, value: %d%n", k, v);
});
Example 3: iterate hashmap java
public static void printMap(Map mp) {
Iterator it = mp.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pair = (Map.Entry)it.next();
System.out.println(pair.getKey() + " = " + pair.getValue());
it.remove(); // avoids a ConcurrentModificationException
}
