LocationManager ve LocationListener Farkı

bu ikisi arasındaki fark nedir?

LocationManager locationManager= (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
        LocationListener locationListener= new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {


            }

            @Override
            public void onStatusChanged(String s, int i, Bundle bundle) {

            }

            @Override
            public void onProviderEnabled(String s) {

            }

            @Override
            public void onProviderDisabled(String s) {

            }
        };
