how to add " span " to each words in the arraylist?

Question

I have one arraylist

  ArrayList al = new ArrayList();
  al.add("tree good has");
  al.add("ok go by");
  al.add("see good");
  al.add("dog");

how to add " span " to each words??? For example:

  <li> 
     <span>tree</span>  
     <span>good</span> 
     <span>has</span> 
  </li>
  <li> 
     <span>ok</span>  
     <span>go</span> 
     <span>by</span> 
  </li>
  <li> 
     <span>see</span>  
     <span>good</span> 
  </li>
  <li> 
     <span>dog</span> 
  </li>

what i tried was: the result of this statement was wrong. because the result is add " span " to each row , not earch word.

 <% for (int i=0; i<  al.size();i++){ %>
    <li><span><%=al.get(i) %><br></span></li>  
 <%} %>

You need further split each line into words. Find below code -

<% for (int i=0; i<  al.size();i++){
%>
   <li>
<%
     for(int j=0;j<al.get(i).split(" ").length;j++){
 %>
        <span><%=al.get(j) %><br></span>  
<%   }%>
   </li> 
<%}%>

how to solve this issue :Multiple annotations found at this line: - Line breakpoint:my.jsp [line: 130] - The method split(String) is undefined for the type Object – bob90937 Nov 03 '16 at 06:00

expected comment... :) array list defined as generic, it should be type specific, `List al = new ArrayList<>();` – Subhrajyoti Majumder Nov 03 '16 at 06:02

You can use the split method and can add the inner loop to achieve the desired result. it will look like

<% for (int i=0; i<  al.size();i++){ 
String[] splitArray = al.get(i).split();%><li>
<% for (int j=0; j<  splitArray.length;j++){ %>
   <span><%=splitArray[j] %></span>  

    <%} %>
</li>
<%} %>

Multiple annotations found at this line: - The method split() is undefined for the type Object ..... for the split, I got the errors – bob90937 Nov 03 '16 at 05:59
Its not the specific list maybe. you can change the line as `String[] splitArray = (String) al.get(i).split();` – Umais Gillani Nov 03 '16 at 06:04
I would recommend to make the list type specific. – Umais Gillani Nov 03 '16 at 06:05
`splitArray.size()` is wrong statement, array does not have any method size. – Subhrajyoti Majumder Nov 03 '16 at 06:14
Thanks @SubhrajyotiMajumder for pointing out. updated the answer. :) – Umais Gillani Nov 03 '16 at 06:19
One more thing - `
<%=splitArray[j] %>
tree
good

You can solve this problem with JSTL. JSTL is better way to using java operations in jsp page. First off all you need to import required libraries to your jsp.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <body>
        <ul>
            <c:forEach items="${al}" var="mWord">
                <li>
                    <c:forEach items="${fn:split(mWord,' ')}" var="word">
                        <span>${word}</span>
                    </c:forEach>
                </li>
            </c:forEach>
        </ul>
    </body>
</html>
