Thread: How to setColor with a for loop?

Hello!

So i'm learning to draw simple graphics with Java... I drew a pie chart using fillArc(.....) and splitted the pie in 8 equal pieces with an angle of
45 each...

I want each slice to have a different color... I was able to do it using a switch case but then i tried to make the code smaller using a
String array with the color names like this:

String sliceColor[] = {"GREEN","ORANGE","BLUE", etc...} 8 color names

and then i used a for loop to draw the 8 filled arcs... but the problem is that i can't change the colors in the loop for each slice using
setColor(Color.sliceColor[loop variable here]); this is where i'm stuck... any way to change to a different color using the loop?

Here's the code so far...

 
//--------------------------------------------
// A Pie chart drawing with 8 slices of 
// 45 degrees each and different colors.
//--------------------------------------------
 
import javax.swing.JApplet;
import java.awt.Graphics;
import java.awt.Color;
 
/*
<applet code = "PieChart" width =1200 height = 650> </applet>
*/
 
public class PieChart extends JApplet
{
   public static final short ARC_ANGLE = 45; //angle constant
 
   //pie slice color array - 8 colors
   String sliceColor[] = {"GREEN","BLACK","ORANGE","WHITE","RED",
   "YELLOW","BLUE","CYAN"};
 
   public void init()
   {
      setBackground(Color.BLACK);
   }
 
   public void paint(Graphics pie)
   {      
      short startAngle = 0;
      for (short sliceNumber = 0;sliceNumber < 8; sliceNumber++)
      {
         pie.setColor(Color.sliceColor[sliceNumber]);  <---------------- this is what i want to make it work  :confused:
         pie.fillArc(300,60,500,500,startAngle,ARC_ANGLE);
         startAngle += 45;
 
      } // end for loop
 
   } // end paint class
 
} // end PieChart class.

Thanks...

way to change to a different color using the loop?

Define an array of Color objects and index into it the same way code indexes into the array of Strings.
The Color class has several static fields that define Color objects. For example: Color.RED
Read the API doc for the Color class to see what fields it has.
