Hi Friend,

Try the following code:

import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class ChangeBackgroundColor extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
PrintWriter out = response.getWriter();
out.println("<html><head>");
out.println("<script>function setbackground(){window.setTimeout( 'setbackground()', 10000);var index = Math.round(Math.random() * 9);var ColorValue = 'FFFFFF'; ");
out.println("if(index == 1)ColorValue = 'FFCCCC'; ");
out.println("if(index == 2)ColorValue = 'CCAFFF';");
out.println("if(index == 3)ColorValue = 'A6BEFF'; ");
out.println("if(index == 4)ColorValue = '99FFFF'; ");
out.println("if(index == 5)ColorValue = 'D5CCBB'; ");
out.println("if(index == 6)ColorValue = '99FF99'; ");
out.println("if(index == 7)ColorValue = 'FFFF99'; ");
out.println("if(index == 8)ColorValue = 'FFCC99'; ");
out.println("if(index == 9)ColorValue = 'CCCCCC'; ");
out.println("document.bgColor=ColorValue;}</script></head>");
out.println("<body onLoad='setbackground();'><h1>Hello World</h1></body></html>");
}
}

Thanks
