Given 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"); } } Which statement is correct?

There are no statements in the question, so I explained the whole code.

Explanation:

A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.

For example, map.put("123", "John Smith");   -> key = 123, value = John Smith

Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.

Note that the key 222 also has Steve Yao for the value, that is totally acceptable.
