Loop Map using Map.Entry in map.entrySet()


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

public class MapEntryTest {
   
    public static void main(String[] args){
       
        Map<String, String > map = new HashMap<String, String>();
       
        //initialize map
        map.put("1", "a");
        map.put("2", "b");
        map.put("3", "c");

        // entry in entrySet
        for (Map.Entry<String, String> entry : map.entrySet()){
            System.out.println("key="+entry.getKey()+" value="+entry.getValue());
        }
    }

}


OUTPUT:
key=3 value=c
key=2 value=b
key=1 value=a
