Class Angle

Object

Angle

All Implemented Interfaces:

Serializable, Comparable<Angle>

Direct Known Subclasses:

Latitude, Longitude

public class Angle
extends Object
implements Comparable<Angle>, Serializable

An angle in degrees. An angle is the amount of rotation needed to bring one line or plane into coincidence with another, generally measured in degrees, sexagesimal degrees or grads.

This class is registered with ClassChanger, which means it can be converted to and from Double.

Since:

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
