Map.Entry interface

Entry interface is innner interface of Map interface
Entry is key + value .

public class Outer {
    public static void main(String args[]) {
        Map<String,Integer> mp = new LinkedHashMap<>();
        Entry<String,Integer> e = entry("sato-a",100);
        Entry<String,Integer> e1 = entry("sato-b",101);
        Entry<String,Integer> e2 = entry("sato-c",102);
        mp = Map.ofEntries(e,e1,e2);
        Set<Entry<String,Integer>> s = mp.entrySet();
        mp.entrySet().forEach((Entry<String,Integer> x) -> System.out.println(x.getKey() + ":" + x.getValue()));
        System.out.println("--------------------");
        for(Entry<String,Integer> en:s) {
            System.out.println(en.getKey() + ":" + en.getValue());
        }
    }
}
