Constructor Details

Longitude

public Longitude(double theta)

Contruct a new longitude with the specified value.

Parameters:

theta - Angle in degrees.

Longitude

public Longitude(String theta)
          throws NumberFormatException

Constructs a newly allocated Longitude object that represents the longitude value represented by the string. The string should represents an angle in either fractional degrees (e.g. 45.5°) or degrees with minutes and seconds (e.g. 45°30'). The hemisphere (E or W) is optional (default to East).

Parameters:

theta - A string to be converted to a Longitude.

Throws:

NumberFormatException - if the string does not contain a parsable longitude.
