java hashmap lambda foreach code example
Example 1: java 8 map foreach
public void iterateUsingLambda(Map<String, Integer> map) {
map.forEach((k, v) -> System.out.println((k + ":" + v)));
}
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());
}
}
