In java, there are several methods for iterating over a hashmap. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18. Removing entries from map in java one reason for iterating over map is removing selected key value pairs from map.

And iterator interface using foreach in java 1.8 version let us move forward and discuss all possible ways to iterate hashmap of arraylist of (string) type 1.

Using an iterator to iterate through a hashmap. Public class main { public static void main(string[] args) { hashmap< string, string> hmap = new hashmap< string, string> (); Iterating over a hashmap using java 8 foreach and lambda. We convert our linkedhashmap to entryset using, set s = lhm.entryset ();
