Explanation / Answer

Dear User, import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Color;
import java.awt.geom.GeneralPath;
import javax.swing.JPanel;
import javax.swing.JFrame;

class TD extends JPanel
{
public void paint( Graphics g )
{
super.paint( g );
Graphics2D g2d = ( Graphics2D ) g;
for ( int i = 0; i < 100; i++ )
{
GeneralPath triangle = new GeneralPath();
int x = ( int ) ( Math.random() * 375 + 25 );
int y = ( int ) ( Math.random() * 375 + 25 );
triangle.moveTo( x, y );
x = ( int ) ( Math.random() * 375 + 25 );
y = ( int ) ( Math.random() * 375 + 25 );
triangle.lineTo( x, y );
x = ( int ) ( Math.random() * 375 + 25 );
y = ( int ) ( Math.random() * 375 + 25 );
triangle.lineTo( x, y );
triangle.closePath();
g2d.setColor(new Color( ( int )
( Math.random() * 256 ), ( int )
( Math.random() * 256 ), ( int )
( Math.random() * 256 ) ) );
g2d.fill( triangle );
}
}
}
class Triangles extends JFrame
{
public static void main( String args[] )
{
JFrame frame = new JFrame("Triangles");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
TrianglesDemo app = new TrianglesDemo();
frame.add(app);
frame.setSize(450,450);
frame.setVisible(true);
}
}
I hope this will helps to You !
