I am getting error saying:
root cause

java.lang.Error: Unresolved compilation problem:
Arrays cannot be resolved

Sorting.process(Sorting.java:38)
Sorting.doGet(Sorting.java:14)
javax.servlet.http.HttpServlet.service(HttpServlet .java:690)
javax.servlet.http.HttpServlet.service(HttpServlet .java:803)

My code:
This is my HTML script

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<p>Sorting arrays</p>
<form action="Sorting" method=get>
<p>1 <input type=text name=word></p>
<input type=submit name=sort value=Submit>
</form>
</body>
</html>

This is my servlet:

Code:



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

public class Sorting extends HttpServlet
{
    public void doGet(HttpServletRequest request,
         HttpServletResponse response)
            throws IOException, ServletException
    {
      String word = request.getParameter("word");
      word = process(word);
      response.setContentType("text/html");
      PrintWriter out = response.getWriter();
      out.println("<html>");
      out.println("<head>");
      out.println("<title>Sorting Servlet</title>");
      out.println("</head>");
      out.println("<body>");
      out.println(word);
      out.println("</body>");
      out.println("</html>");
      }

      public void doPost(HttpServletRequest request,
      HttpServletResponse response)
      throws IOException, ServletException
      {
      doGet(request, response);
      }

      public String process(String word) {
      StringBuilder buf = new StringBuilder(512);
      if(word != null && word.trim().length() != 0) {
      String arr[] = word.replaceAll("\\s+", "").split(",");
      Arrays.sort(arr);
      for(String str : arr) {

      buf.append(str).append("<br>");
      }

      }

      else {
      buf.append("<br>").append("No input supplied").append("<br>");
      }
      return(buf.toString());
      }
      }

You've missed an import in your class. The Arrays class is in the java.util package.

Code:

import java.util.Arrays;
