Analyze the following code:

public class Test {
public static void main(String[] args) {

Map map = new HashMap();

map.put("123", "John Smith");

map.put("111", "George Smith");

map.put("123", "Steve Yao");

map.put("222", "Steve Yao");

}
}

◦ After all the four entries are added to the map, "Steve Yao" is a key that corresponds to the value "222".
◦ After all the four entries are added to the map, "123" is a key that corresponds to the value "John Smith".
◦ After all the four entries are added to the map, "John Smith" is a key that corresponds to the value "123".
◦ After all the four entries are added to the map, "123" is a key that corresponds to the value "Steve Yao".
◦ A runtime error occurs because two entries with the same key "123" are added to the map.
