Constructor Detail

Longitude

public Longitude(double theta)

Contruct a new longitude with the specified value.

Parameters:

theta - Angle in degrees.

Longitude

public Longitude(java.lang.String theta)
          throws java.lang.NumberFormatException

Constructs a newly allocated 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 .

Throws:

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