import java.io.*;
import javax.servlet.*;

public class SecondClass extends GenericServlet
{

public void service(ServletRequest request,ServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out=response.getWriter(); // LINE 1
out.println("welcome to servlet ! ");
out.close();
}

}

Can someone tell me how does PrintWriter work ? Please explain LINE 1 also.

This will return PrintWriter object
See Servlet API

Rahul,

PrintWriter is the class which helps to print output in the specified locations like FileOutputStrem/File/Console. in the above code what you need to understand is from the response object we can obtain the writer which helps out send the required out put to client.
