Constructor Detail

Angle

public Angle(double theta)

Constructs 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 decimal degrees.

Returns:

The angle value in degrees.

radians

public double radians()

Returns the angle value in 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

Parameters:

object - The object to compare with this angle for equality.

Returns:

true if the given object is equal to this angle.

compareTo

public int compareTo(Angle that)

Compares two Angle objects numerically. The comparison is done as if by the Double.compare(double,double) method.

Specified by:

compareTo in interface Comparable<Angle>

Parameters:

that - The angle to compare with this object for order.

Returns:

-1 if this angle is smaller than the given one, +1 if greater or 0 if equals.

toString

public String toString()

Returns a string representation of this Angle object.

Overrides:

toString in class Object
