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
