Java HashMap put in an enhanced for loop just like an ArrayList

Question

For example, I can loop an ArrayList like this

for (String temp : arraylist)

Can I loop a HashMap by using the similar method?

Answer 1

You can iterate over the keys, entries or values.

for (String key : map.keySet()) {
    String value = map.get(key);
}

for (String value : map.values()) {
}

for (Map.Entry<String,String> entry : map.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
}

This is assuming your map has String keys and String values.
