how to iterate through hashmap in java 8 code example

Example 1: java 8 loop in map

Map<String, Integer> items = new HashMap<>();
items.put("A", 10);
items.put("B", 20);
items.put("C", 30);
items.put("D", 40);
items.put("E", 50);
items.put("F", 60);

items.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

items.forEach((k,v)->{
	System.out.println("Item : " + k + " Count : " + v);
	if("E".equals(k)){
		System.out.println("Hello E");
	}
});

Example 2: java 8 map foreach

public void iterateUsingIteratorAndEntry(Map<String, Integer> map) {
    Iterator<Map.Entry<String, Integer>> iterator = map.entrySet().iterator();
    while (iterator.hasNext()) {
        Map.Entry<String, Integer> entry = iterator.next();
        System.out.println(entry.getKey() + ":" + entry.getValue());
    }
}
