| RGB | | final public class RGB implements SerializableCompatibility(Code) | | Instances of this class are descriptions of colors in
terms of the primary additive color model (red, green and
blue). A color may be described in terms of the relative
intensities of these three primary colors. The brightness
of each color is specified by a value in the range 0 to 255,
where 0 indicates no color (blackness) and 255 indicates
maximum intensity.
The hashCode() method in this class uses the values of the public
fields to compute the hash value. When storing instances of the
class in hashed collections, do not modify these fields after the
object has been inserted.
Application code does not need to explicitly release the
resources managed by each instance when those instances are no longer
required, and thus no dispose() method is provided.

if they represent the same object using a class
specific comparison. | | public float[] | getHSB()
Returns the hue, saturation, and brightness of the color. | | public int | hashCode()
Returns an integer hash code for the receiver. | | public String | toString()
Returns a string containing a concise, human-readable
description of the receiver. |
| blue | | public int blue(Code) | | the blue component of the RGB
|
| green | | public int green(Code) | | the green component of the RGB
|
| red | | public int red(Code) | | the red component of the RGB

red - the red component of the new instance
Parameters:
green - the green component of the new instance
Parameters:
blue - the blue component of the new instance
exception:

| equals | | public boolean equals(Object object)(Code) | | Compares the argument to the receiver, and returns true
if they represent the same object using a class
specific comparison.
Parameters:
object - the object to compare with this object true if the object is the same as this object and false otherwise

| hashCode | | public int hashCode()(Code) | | Returns an integer hash code for the receiver. Any two
objects that return true when passed to
equals must return the same value for this
method.
