The color palette

Before getting into the details of the class, I will explain the color palette. The color palette is produced by a method named getColorPalette , shown in its entirety in Listing 26 . This is a utility method that is called by the inner classes named CanvasType2surface and CanvasType2scale .

Listing 26. The method named getColorPalette.
Color[] getColorPalette(){//Note that the following is an initialized // 1D array of type Color.Color[] colorPalette = {Color.BLACK,// 0, 0, 0 Color.GRAY,// 128,128,128Color.LIGHT_GRAY,// 192,192,192 Color.BLUE,// 0, 0,255new Color(100,100,255),//100,100,255 new Color(140,140,255),//140,140,255new Color(175,175,255),//175,175,255 Color.CYAN,// 0,255,255new Color(140,255,255),//140,255,255 Color.GREEN,// 0,255, 0new Color(140,255,140),//140,255,140 new Color(200,255,200),//200,255,200Color.PINK,// 255,175,175 new Color(255,140,255),//255,140,255Color.MAGENTA,// 255, 0,255 new Color(255,0,140), //255, 0,140Color.RED,// 255, 0, 0 new Color(255,100,0),// 255,100, 0Color.ORANGE,// 255,200, 0 new Color(255,225,0),// 255,225, 0Color.YELLOW,// 255,255, 0 new Color(255,255,150),//255,255,150Color.WHITE};// 255,255,255return colorPalette; }//end getColorPalette

The getcolorpalette method

The purpose of this method is to establish a color palette containing references to Color objects representing 23 distinct colors and shades of gray. The references are stored in a one-dimensional array object aselement type Color . The values shown in comments in Listing 26 represent the values of red, green, and blue required to produce that specificcolor.

As you can see, some of the elements in the array refer to Color objects defined as named constants (public final variables) in the Color class. Other elements in the array refer to Color objects that are instantiated using red, green, and blue color values of my ownchoosing. The actual colors represented by these objects, going from top to bottom, match the colors shown in the calibration scale for the rightmost imagein Figure 1 .

Rearrange and add new colors

If you would like to do so, you can rearrange the colors in the array. This will result in different colors being adjacent to one another in the calibrationscale. Also if you would like to do so, you can remove colors from the array or add new colors of your own choosing to the array. The overridden paint methodsin the classes named CanvasType2surface and CanvasType2scale are designed to take such changes into account.

The CanvasType2surface class

You can view the entire class named CanvasType2surface in Listing 29 near the end of the module. Because of the similarity of this class to others that I have previously discussed, I will limit my discussion to theportions of the overridden paint method that distinguish this class from the others.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
