Looping Hashmap In Java Looping Hashmap In Java . There are multiple ways to iterate, traverse or loop through map, hashmap, or treemap in java and we are all familiar with either all of those or some of those. We also can use an iterator or foreach loop. Another way to iterate a map in java is using keyset () method which returns a set containing keys of the map or values () method that returns a collection view of the map.
