how to draw 4small circles in a square format and draw edge between them without direction in netbeans,java?
anyone pls help me
That gets down to Graphics2D and math. Suppose you have a JFrame and you add a JPanel called DisplayPanel...
public class DisplayPanel
extends JPanel {
private BufferedImage image = null;
public DisplayPanel() {
setLayout( null );
}
public void paintComponent( Graphics g ) {
if( image == null ) {
doLayout();
}
g.drawImage( image,0,0,null);
}
private void doLayout() {
Rectangle r = getBounds();
GraphicsConfiguration gc = getGraphicsConfiguration();
image = gc.createCompatibleImage(
r.width, r.height,
Transparency.TRANSLUCENT);
Graphics2D g2 = image.createGraphics();
// now we can draw and we have dimensions!!!
g2.setColor( Color.black );
g2.setStroke( new BasicStroke(2f) );
g2.draw( new Ellipse2D.Float( 12.0f, 12.0f, 24.0f, 24.0f) );
g2.draw( new ellipse2D.Float( 36.0f, 12.0f, 24.0f, 24.0f) );
g2.draw( new Ellipse2D.Float( 12.0f, 36.0f, 24.0f, 24.0f) );
g2.draw( new Ellipse2D.Float( 36.0f, 36.0f, 24.0f, 24.0f) );
g2.draw( new Rectangle2D.Float( 12.0f, 12.0f, 48.0f, 48.0f) );
// free up the memory
g2.dispose();
}
}
