} 2.If you're only interested in the keys, you can iterate through the "keySet()" of the map: Map<String, Object> map =...;for(String key : map.keySet()) {//...} 3.If you only need the values, use "value()": for(Object value : map.values()) {//...} 4.Finally, i...

In this program, we have illustrated the use offoreachloop for iterating over a map. We have created a map namedmyBikesand then used theforeachto iterate over it, using the tuple access method. Iterating over the map using the iterator method ...

Using a forEach method: If you are using Java 8 or later, you can use the forEach method of the Map interface to iterate over the entries in the Map. This method takes a BiConsumer as an argument, which is a functional interface that represents an operation that takes two arguments an...
