java Map 迭代key,value 最简洁的方法

import java.util.HashMap;
import java.util.Map;

public class EntrySets {

    public static void main(String[] args) {
        Map<Object, Object> map = new HashMap<Object, Object>();
        map.put("k1", "v1");
        map.put("k2", "v2");
        getItem(map);

    }

    static void getItem(Map map) {
        map.forEach((key, value) -> print(key + ":" + value));
    }

    static void iterByKey(Map map) {
        /**  iter map  by key */
        for (Object k : map.keySet()) {
            String v = map.get(k).toString();
        }
    }

    static void print(Object o) {
        System.out.println(o);
    }
}
