How to put an Entry into a Map?

Question

Is there any way that I can put a whole Entry object to a Map object like:

map.put(entry);

instead of passing a k

Answer 1

To instantiate a Map with Entries (in the same way as you can do Arrays.asList(T... a) or Sets.newHashSet(T... a) in Google Guava library, I found this:

import java.util.AbstractMap;
import java.util.Map;

public class MapWithEntries {

    private static final Map.Entry ENTRY_1 = new AbstractMap.SimpleEntry<>("A", "Hello");
    private static final Map.Entry ENTRY_2 = new AbstractMap.SimpleEntry<>("B", "World");

    private static final Map MAP_WITH_ENTRIES = Map.ofEntries(ENTRY_1, ENTRY_2);
}
