Arc MIDlet Example
In the previous draw arc example, we have explained how to draw an arch on
the screen. But in this example we are going to show how to draw arc at
different locations. To explain it in better way we have described all the
methods that used in this application below..
- g.setColor(255, 162, 117);
- g.fillRect(0, 0, width, height);
- g.setColor(0, 0, 255);
- g.fillArc(0, 0, width/2, height/2, 0, 90);
- g.setStrokeStyle(Graphics.DOTTED);
- g.setColor(0xffff00);
- g.drawRect(0, 0, width/2, height/2);
- g.setStrokeStyle(Graphics.SOLID);
- g.setColor(0, 0, 255);
- g.fillArc(width/2, 0, width/2, height/2, 0, -90);
- g.setStrokeStyle(Graphics.DOTTED);
- g.setColor(0xffff00);
- g.drawRect(width/2, 0, width/2, height/2);
- g.setStrokeStyle(Graphics.SOLID);
- g.setColor(0, 0, 255);
- g.fillArc(0, height/2, width, height/2, -90, -180);
- g.setStrokeStyle(Graphics.DOTTED);
- g.setColor(0xffff00);
- g.drawRect(0, height/2, width, height/2);
The Application is as follows:
Source Code of ArcsExample.java
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class ArcsExample extends MIDlet{
private Display display;
public void startApp(){
Canvas canvas = new ArcsCanvas();
display = Display.getDisplay(this);
display.setCurrent(canvas);
}
public void pauseApp(){}
public void destroyApp(boolean unconditional){}
}
class ArcsCanvas extends Canvas {
public void paint(Graphics g) {
int width = getWidth();
int height = getHeight();
g.setColor(255, 162, 117);
g.fillRect(0, 0, width, height);
g.setColor(0, 0, 255);
g.fillArc(0, 0, width/2, height/2, 0, 90);

g.setColor(0xffff00);
g.drawRect(0, height/2, width, height/2);
}
