1,331,252 | 1,331,253 | Parse input from string containing ints | <p>I am trying to get input from a string containing ints. So when a user types in the command "getrange(1,12)" I need to read the inital command as a string, and the two numbers inside it as an ints.

<p>I am having a string of words separated by comma(,) and I need to tokenize or split the main string into substrings. For e.g, <code>string="file1,param1,file2,param2,file3,"</code>
What the string means is, a list of all file names and the parameter passed to it. Like,
for file1--> param1,
file2-->param2 and
file3 nothing parameter exists.</p>
<p>So I need to extract the file names and params, if any. If no params I need to get the empty string("").</p>
<pre><code>import java.util.ArrayList;
import java.util.List;
import java.util.StringTokenizer;
public class XStringTokenizer {
/**
* @param args
*/
public static void main(String[] args) {
String str = new String("File1,param1,File2,");
List list = new ArrayList();
System.out.println(str.split(",").length);
String[] string = str.split(",");
for(int i=0;i<string.length;i++){
list.add(string[i]);
}
System.out.println(list);
}
}
</code></pre>
<p>Current output for the above sample code is [File1,param1,File2] but expected output is [File1,param1,File2,]. Basically I should not miss the end empty string after the 3rd comma in the above <code>str</code> String.</p>

<p>So I'm looking to test the output of this method to ensure it actually preserves these characters.<br>

I think I need to build a format template, compile it with <code>Pattern</code> and then use it with <code>Matcher</code> with the output string of my test method

140,043 | 140,044 | Inconsistent page redirections in php | <p>I have set the session on all pages in my admin panel like so:</p>
<pre><code>session_start();
if(!isset($_SESSION['username']))
header("Location: login.php?e=please+login+first");
</code></pre>
<p>This seemed to be working properly on all my pages, but now when I refresh my page or click on a link, the page automatically redirects to <code>login.php</code>. This seems to happen infrequently. I don't understand what is causing this problem</p>
<p>As an example, my menu bar is like:</p>
<pre><code>home : doctors: hospitals: feedback
</code></pre>
<p>If I am on <code>hospitals.php</code>, then after a few mins I click on <code>feedback.php</code> (or any other link) I get redirected to <code>login.php</code>. The next time if I again click on the link I will not get redirected</p>
<p>Here is my dologin.php code</p>
<pre><code>$qry = "select * from admin where username='$uname' and password='$pwd'";
//echo $qry;exit;
$rs = mysql_query($qry,$con);
if($rec= mysql_fetch_array($rs))
{
$_SESSION['username'] = $rec['username'];
header("Location: index.php");
}
else if (empty($uname))
{
header("Location: login.php?e=Please+enter+username");

<p>I know about abstract classes and interfaces. But I wish to know a real time scenario in which we need to use only abstract class but not interface and only interface but not an abstract class.. Can any one suggest me some example like that.</p>
<p>I guess the second one is used when multiple inheritance need arises i.e. A class is already inheriting some class and so we cant use an abstract class here .. We need to use only interface. In the same way I need an example In which we use only abstract but not interface.</p>
<p>EDITED</p>
<p>Just to add some more points for interface.</p>
<p>Consider the java library collections</p>
<pre><code> Collections
List Set
</code></pre>
<p>All 3 are interfaces but the major thing , though they have functions which are common that is add , addAll, contains,containsAll etc. List implements in its own and set implements in another way ( telling about duplication ). Set does not allow duplicates list allows duplicates. </p>
<p>So what I am trying to say is when ever there is no common features for sub-interface of super-interface we have to go for interface</p>
<p>But if there is some common functionality which both has then keep it as to be abstract class. </p>
<p>I need a practical example done in java api.
Thanks.
