### Question:
LatLngSpan implements Parcelable { public double getLatitudeSpan() { return mLatitudeSpan; } 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 testLatitudeConstructor() { double latitude = 1.23; LatLngSpan latLngSpan = new LatLngSpan(latitude, 0.0); assertEquals("latitude in constructor", latLngSpan.getLatitudeSpan(), latitude, DELTA); }
