Don't worry if you feeling tense after see this coding but I just want to inform the new guys who are new to the J2EE, the syntax of the coding is fixed and it's already ready for you by netbeans, you just have to do your part of coding in the middle of this.
In this example, this is just the simple small random number program that we see in core java but the difference is, this is ruining on web browser. Here, I have write the name of the servlet is GuessWhat but you can name it whatever you like so don't worry about that.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class GuessWhat extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
String d1=Integer.toString((int)((Math.random()*99)));
String d2=Integer.toString((int)((Math.random()*99)));
out.println("<html> <body> "+ "<h1 align=centre>Let's guess the number by pressing F5</h1>"+
"<h2> This time " + d1 + " and "+ d2 +" are the right answer, now time to guess another numbers !</h2>"+"</body>"+"</html>");
}
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
public String getServletInfo() {
return "Short description";
}
}
