iterate over a 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 iterateUsingLambda(Map<String, Integer> map) {
    map.forEach((k, v) -> System.out.println((k + ":" + v)));
}
