Write a program in Java to draw various geometric shapes like circle, line, rectangle and etc.
import java.awt.*;
import javax.swing.*;

class MFrame extends JFrame {
    MFrame() {
        setTitle (" Draw Shapes ");
        setSize (600 , 500);
        Container c = getContentPane ();
        c.add (new MPanel());
    }
}

class MPanel extends JPanel {
    public void paintComponent ( Graphics g ) {
        super.paintComponent ( g );
        g.setColor( Color.pink );
        g.drawRoundRect( 30 , 30 , 340 , 340 , 20 , 30 );

        g.setColor( Color.blue );
        g.drawRect( 50 , 50 , 300 , 300 );

        g.setColor( Color.blue );
        Polygon p = new Polygon ( );
        p.addPoint ( 200, 50 );
        p.addPoint ( 325, 325 );
        p.addPoint ( 75, 125 );
        p.addPoint ( 325, 125 );
        p.addPoint ( 75, 325 );
        g.drawPolygon ( p );

        g.setColor( Color.red );
        g.drawLine ( 300 ,100  , 450 , 250 );

        g.setColor( Color.red );
        g.drawArc ( 50 , 50 , 300 , 300 , 30 , 400 );

        g.setColor( Color.blue );
        g.drawOval( 100 , 100 , 50 , 50 );
        g.drawOval( 250 , 100 , 50 , 50 );

        g.setColor( Color.red );
        g.drawArc ( 100 , 200 , 200 , 100 , 200 , 150 );

        g.setColor( Color.red );
        g.drawLine ( 200, 150 , 200 , 250 );
        g.drawLine ( 150 , 250 , 250 , 250 );
    }

class Shapes1 {
    public static void main (String[] m) {
        JFrame j = new MFrame ( );
        j.show ();
    }
}
