Latitude measures how far north or south of the equator a place is located. The equator is situated at 0°, the North Pole at 90° north (or 90°, because a positive latitude implies north), and the South Pole at 90° south (or –90°). Latitude measurements range from 0° to (+/–)90°.

Longitude measures how far east or west of the prime meridian a place is located. The prime meridian runs through Greenwich, England. Longitude measurements range from 0° to (+/–)180°.

In your setter for latitude, check if the value being set falls between -90 and 90 degrees. If it doesn't, throw an exception. For your longitude, check to see if the value falls between -180 and 180 degrees. If it doesn't, throw an exception.
