Looks like each entry should be wrapped in its own `Map.entry(K,V)` before being passed to `Map.ofEntries()`

Change:

From

`Map<String, Integer> temperatures = Map.ofEntries(Map.entry("Mon", 30, "Tue", 28, "Wed", 32));`

To 

`Map<String, Integer> temperatures2 = Map.ofEntries(
    Map.entry("Mon", 30),
    Map.entry("Tue", 28),
    Map.entry("Wed", 32)
);`
