29 Dec 2011 There are multiple ways to iterate, traverse or loop through Map, HashMap or TreeMap in Java and we all familiar of either all of those or some of those. How to traverse or loop Map, HashMap or TreeMap in Java. Here we will use new foreach loop introduced in JDK5 for iterating over
Below example shows how to read elements from Hashtable. You can iterate through each and every element by getting all keys as set object. Using each
7 Feb 2010 You have the key right? Use the key to get the value out of the map, and you have all the mappings. For example in Java with String as type for
20 Nov 2010 In Java 1.8 (Java 8) this has become lot easier by using forEach method from Here is an example where a Lambda Expression is used:
30 Jun 2009 Extracted from the reference How to Iterate Over a Map in Java: implementation ( HashMap , TreeMap , LinkedHashMap , Hashtable , etc.).
This Java Example shows how to iterate through the values contained in the Hashtable object.
28 Feb 2010 The following example iterates over a Map of Integer , String pairs, . You can find more information about Hashtable methods in the Java API
This Java Example shows how to iterate through the keys contained in the Hashtable object.
20 Aug 2015 Map<String, Integer> items = new HashMap<>(); items.put("A", 10); 1.2 In Java 8, you can loop a Map with forEach + lambda expression.
In this example we will see how to iterate a Hashtable using Iterator. Using Iterator we can display Hashtable key and value separately for each pair of el.
