Write a java program in multithreading using applet for drawing temple.

import java.awt.*;

// HTML tag to run this applet:
// <applet code="TempleApplet.class" width="500" height="500"></applet>

        t.start();
    }

        // Draw ground
        g.setColor(new Color(34,139,34)); // green
        g.fillRect(0, 400, 500, 100);

        // Draw main temple base
        g.setColor(new Color(210,180,140)); // tan
        g.fillRect(150, 250 - moveY, 200, 150); // main building

        // Draw dome on top
        g.setColor(Color.ORANGE);

                Thread.sleep(200); // 200 milliseconds delay
            }
