How to calculate Latitude and Longitude of a point by distance and direction from another point

I'm looking to calculate the latitude and longitude of where to place a marker that is a specific distance and direction from a known position's latitude and longitude. This is for an Android app (in Java) using the HERE mapping API.

Our Android Mobile SDK (Java) currently supports calculating distance between two geocoordinates (lat, lon) via the distanceTo method of the Geocoordinate class.

https://developer.here.com/documentation/android-premium/api_reference_java/index.html

The method you are requesting is currently not provided. However, our JavaScript SDK provides a walk method of the H.geo.Point class. This method returns the destination point, based on the given distance and bearing relative to the current point.

https://developer.here.com/documentation/maps/topics_api/h-geo-point.html#h-geo-point__walk

The algorithm is based on the Haversine formula and so you can also use the formula to calculate the target point yourself.
