Any way to stream a map like “(k,v)” instead of working with (entry)?

Question

Basically I look for a way to avoid working with

entry -> entry.getValue

and

entry -> entry.getKey

Answer 1

Using guavas Maps.transformEntries:

Map m = new HashMap<>();
m.put("foo", 5);
m.put("bar", 7);
m.put("baz", 42);

Map newMapView = Maps.transformEntries(m, (k, v) -> k + ":" + v);
