Constructor Detail

Angle

public Angle(double theta)
Contructs a new angle with the specified value.

Parameters:
theta - Angle in degrees.

Angle

public Angle(String string)
      throws NumberFormatException
Constructs a newly allocated Angle object that represents the angle 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').

Parameters:
string - A string to be converted to an Angle.
Throws:
NumberFormatException - if the string does not contain a parsable angle.
Method Detail

degrees

public double degrees()
Returns the angle value in degrees.


radians

public double radians()
Returns the angle value in radians.


hashCode

public int hashCode()
Returns a hash code for this Angle object.

Overrides:
hashCode in class Object

equals

public boolean equals(Object object)
Compares the specified object with this angle for equality.

Overrides:
equals in class Object

compareTo

public int compareTo(Angle that)
Compares two Angle objects numerically. The comparaison is done as if by the Double.compare(double,double) method.

Specified by:
compareTo in interface Comparable<Angle>

toString

public String toString()
Returns a string representation of this Angle object.

Overrides:
toString in class Object
