### Question:
LatLngSpan implements Parcelable { public double getLongitudeSpan() { return mLongitudeSpan; } private  LatLngSpan(@NonNull Parcel in);  LatLngSpan(double latitudeSpan, double longitudeSpan); double getLatitudeSpan(); void setLatitudeSpan(double latitudeSpan); double getLongitudeSpan(); void setLongitudeSpan(double longitudeSpan); @Override boolean equals(Object object); @Override int describeContents(); @Override void writeToParcel(@NonNull Parcel out, int flags); @Override int hashCode(); static final Parcelable.Creator<LatLngSpan> CREATOR; }### Answer:
@Test public void testLongitudeConstructor() { double longitude = 1.23; LatLngSpan latLngSpan = new LatLngSpan(0.0, longitude); assertEquals("latitude in constructor", latLngSpan.getLongitudeSpan(), longitude, DELTA); }
