Java's Use of Colors

Part of Java's use of Graphics class is the use on colors. To set color to our text, we can use the code below:

graphicObject.setColor(color_constant);  

ex:

myObject.setColor(Color.pink);

To use our own color variants, we can have a constructor for color:

Color colorObject = new Color(red_extent,green_extent,blue_extent);

ex:

Color newColor = new Color(200,10,255); 

 where this constructor can create a light blue color. Then we use the same to set the text color as indicated below:

myObject.setColor(newColor);

A program below demonstrates various color variants.

/* sample program on graphics */

import java.applet.*;
import java.awt.*;


public class GraphicsDemoColor extends Applet {

Font littleFont = new Font("Helvetica",Font.ITALIC,6);


public void paint(Graphics gr){
int r,g,b;
int x=0,y=0;

for(r=255;r>=0;r-=20)
for(g=255;g>=0;g-=20)
for(b=255;b>=0;b-=20)
{
Color variety = new Color(r,g,b);
gr.setColor(variety);
gr.drawString("X", x, y);
x+=5;
if (x >=400)
{ x=0;
y+=10;

}
}
