Color Control
colors enhance the appearance of a program and help convey meaning.
For example, a traffic light has three different color lights—red indicates stop, yellow indicates caution and
green indicates go.
Class Color defines methods and constants for manipulating colors in a Java program.
public Color( int r, int g, int b )
Creates a color based on red, green and blue contents expressed as integers
from 0 to 255.
public Color( float r, float g, float b )
Creates a color based on red, green and blue contents expressed as floatingpoint
values from 0.0 to 1.0.
public int getRed() // Color class
Returns a value between 0 and 255 representing the red content.
public int getGreen() // Color class
Returns a value between 0 and 255 representing the green content.
public int getBlue() // Color class
Returns a value between 0 and 255 representing the blue content.
public Color getColor() // Graphics class
Returns a Color object representing the current color for the graphics context.
public void setColor( Color c ) // Graphics class
Sets the current color for drawing with the graphics context
