2. Iterate through a HashMap - java - Stack Overflow

   stackoverflow.com/questions/1066589

   Method #1: Iterating over entries using a For-Each loop. This is the most common method and is preferable in most cases. It should be used if you need both map keys and values in the loop. Map<Integer, Integer> map = new HashMap<Integer, Integer>(); for (Map.Entry<Integer, Integer> entry : map.entrySet()) {.

3. How do I efficiently iterate over each entry in a Java Map?

   stackoverflow.com/questions/46898

   The official way to do this is to call map.entrySet(), which returns a set of Map.Entry, each of which contains a key and a value (entry.getKey() and entry.getValue()). In an idiosyncratic implementation, it might make some difference whether you use map.keySet(), map.entrySet() or something else.

4. java collections foreach java-5 - Stack Overflow

   stackoverflow.com/questions/585654

   Although this answer does not provide a Java 5 answer, it does answer the part of the question related to both easier and higher, since higher versions of Java do provide an easier option than Java 5 does. I can't help but think that the effort which went into criticising this answer, could have, instead, gone into improving it.

5. iterating over and removing from a map - java - Stack Overflow

   stackoverflow.com/questions/1884889

   Maybe you can iterate over the map looking for the keys to remove and storing them in a separate collection. Then remove the collection of keys from the map. Modifying the map while iterating is usually frowned upon. This idea may be suspect if the map is very large.

6. java - how to iterate a list like List<Map<String ... - Stack...

   stackoverflow.com/questions/5787079

   1. This is an easy way to iterate over a list of Maps as my starting point. My List had one Map object inside with 3 values. List<Map<String, Object>>. using Java's functional programming in a rather short and succinct manner. The purpose here was to pull out all the maps stored in a list and print them out.

7. java - Iterating over keys and values in a Map - Stack Overflow

   stackoverflow.com/questions/11537101

   9. You can use Entry<String,String> and iterate over it with a for-each loop. You get the Entry object by using Map.entrySet(). The key and value from an entry can be extracted using Entry.getKey() and Entry.getValue() Code example: Map<String, String> someMap; for (Entry<String,String> entry : someMap.entrySet()) {.

8. loops - How to iterate through a Map in java? - Stack Overflow

   stackoverflow.com/questions/43015098

   1. so if it's a Map, just get the keySet () and iterate thorughit by for (String key : bucketMap.ketSet ()) { /* entry type ex a List, Map, Class etc that is the maps value here*/ ) = bucketMap.get (key) } ie Map<key, List<Value>> would be List<value> = buckeyMap.get (key); – Mikenno.

9. javascript - How to iterate a Map () object? - Stack Overflow

   stackoverflow.com/questions/54513690

   Maps provide three ways to get iterators for their contents: keys - Iterates the keys in the map; values - Iterates the values; entries - Iterates the key and values, giving you [key, value] arrays (this is the default) As Nina notes, Maps also provide forEach, which loops through their contents giving the callback the value, key, and map as ...

10. java - How to iterate over a TreeMap? - Stack Overflow

    stackoverflow.com/questions/1318980

    FYI, EntrySet is the preferred way to iterate through any Map since EntrySets are by specification reflective and always represent the state of data in the Map even if the Map underneath would change.

11. lambda - forEach loop Java 8 for Map entry set - Stack Overflow

    stackoverflow.com/questions/32264773

    This immediately reveals that map.forEach() is also using Map.Entry internally. So I would not expect any performance benefit in using map.forEach() over the map.entrySet().forEach(). So in your case the answer really depends on your personal taste :) For the complete list of differences please refer to the provided javadoc links. Happy coding!
