Re: Why javascript does not work on firefox?

You must be using browser specific features. IE is notorious in making your code run even when it is not correct. Paste the code and we will try to help you out. The only advice we can give you is to develop for Firefox so the possibility of the code working on other browsers is more plus you get a nice Error Console and tools like FireBug.

Re: Reading numbers from a text file

You need to specify the delimiter keeping in mind that its a regular expression pattern. If your input from the file is nothing but numbers separated by ',' without any space in between them, the code posted by you must work.

I am assuming that your code won't work since the delimiter you gave was only a single ',' while your input must have had spaces between the number and comma. (eg. 1, 3, 3). You should have input in this format (1,2,3,4).

If you want your code to work for something like(1, 2, 3,4, 5) :

String sample = "1 ,  2 , 3 ,4,    5";
st = new Scanner(sample).useDelimiter("\\s*,\\s*");
int k;
while(st.hasNextInt())
{
    k = st.nextInt();
    System.out.println(k);
}

Re: -sigh- Parents.

Now for something which is thought provoking and on topic....

A real life story from Seoul
My mom only had one eye. I hated her... she was such an embarrassment. My mom ran a small shop at a flea market. She collected little weeds and such to sell... anything for the money we needed she was such an embarrassment. There was this one day during elementary school.
I remember that it was field day, and my mom came. I was so embarrassed.
How could she do this to me? I threw her a hateful look and ran out. The next day at school..."Your mom only has one eye?!" and they taunted me.
I wished that my mom would just disappear from this world so I said to my mom, "Mom, why don't you have the other eye?! You're only going to make me a laughingstock. Why don't you just die?" My mom did not respond. I guess I felt a little bad, but at the same time, it felt good to think that I had said what I'd wanted to say all this time.
Maybe it was because my mom hadn't punished me, but I didn't think that I had hurt her feelings very badly.
That night...I woke up, and went to the kitchen to get a glass of water. My mom was crying there, so quietly, as if she was afraid that she might wake me. I took a look at her, and then turned away. …

Re: date comparison

There are a lot many ways of comparing dates depending on the source of dates and which class you are using to represent them (Date, java.sql.Date, Calendar), which would accordingly require some conversion.

Here is a simple example of comparing two java.util.Date objects.

public static void main(String[] args) throws ParseException
{
    Date today = new Date();
    Date before = new SimpleDateFormat("dd/MM/yyyy").parse("26/07/2007");
    if(today.after(before))
    {
        System.out.println("[" + today + "] lies after [" + before + "]");
    }
    else
    {
        System.out.println("[" + today + "] lies before or is the same as [" + before + "]");
    }
}

Re: date comparison

Check the 'before()', 'after()' and 'equals()' methods of the Date or the Calendar class.

Without knowing the scenario, it would be difficult to suggest anything. Since one of the values is in the database, do the comparison in the servlet itself.

Re: javascript and css

No, as far as I know, you can't do that. But you can surely get hold of all the elements which use that class and change their property which is what you must be aiming for, methinks.

    getElementsByClassName = function (needle)
    {
      var         my_array = document.getElementsByTagName("*");
      var         retvalue = new Array();
      var        i;
      var        j;

      for (i = 0, j = 0; i < my_array.length; i++)
      {
        var c = " " + my_array[i].className + " ";
        if (c.indexOf(" " + needle + " ") != -1)
          retvalue[j++] = my_array[i];
      }
      return retvalue;
    }

    function changeColor(name, color)
    {
        var elements = getElementsByClassName(name);
        for(var i = 0; i < elements.length; ++i)
        {

Re: problem encountered while running a jsp on tomcat 5.5

The URI you specify in your TLD file should be distinct and non empty. The URI used by your JSP file has got nothing to do with the absolute path of your TLD file. Just provide a arbitrary URI string like "http://yourname.com" in the taglib file and use the same in the JSP file.

If you are still getting errors paste the XML file.

Re: help with hangman program

Looping through each char in a string

public class Test
{
   public static void main ( String[] args )
   {
      String crap = "Hello";
      //loop through each char
      for ( int i = 0; i < crap.length(); i++ )
      {
         System.out.println ( crap.substring ( i, i + 1 ) );
      }
   }
}

Or better...

public class Test
{
   public static void main ( String[] args )
   {
      String crap = "Hello";
      //loop through each char
      for ( int i = 0, limit = crap.length(); i < limit; i++ )
      {
         System.out.println(crap.charAt(i));
      }
   }
}

- No need of calculating the length of the string for each iteration.
- A lighter function charAt() is much recommended if you only want characters rather than using the more generic substring() function.

Re: plz tell y it is?

In the case of OP's code, the overloaded method took arguments of type Object and String which is a subclass of Object i.e. a specialized object. Hence the String version of the code is called.

In case of Kashyap's code, the overloaded method took arguments of type String and Test, both of which were subclasses or Object i.e. specialized objects and hence the overloaded method was declared to be ambiguous.

Re: Open.window popup

I don't properly understand what you are trying to do here, but as far as I can make out, I guess you want to create a new window and allow it to load in the background while the user keeps on working with the original window.

// ee.html
<html>
<head>
    <script>
    function doSome()
    {
        var wnd = window.open("dd.html");
        if(!wnd.opener)
            wnd.opener = self;
    }
    </script>
</head>
<body>
    <input type="button" value="Open Window" id="btn" onclick="doSome();" />
</body>
</html>

// dd.html
<html>
<head>
    <script>
    function shiftFocus()
    {
        opener.focus();
    }
    </script>
</head>
<body onload="shiftFocus();">
    <div>This really is something.</div>

Re: Switch Statement with String

Bench has given a good suggestion. But if you are not allowed to use maps, try using two parallel string arrays in which the location of the name of the animal and its description resides in the same location in their respective arrays.

const int SIZE = 3;
string animal[SIZE] = {"dog", "cat", "pig"};
string desc[SIZE] = {"bark", "meow", "oink"};

bool found = false;
for(int i = 0; i < SIZE; ++i)
{
    if(animal[i] == input)
    {
        cout << animal[i] << " -> " << desc[i];
        found = true;
        break;
    }
}
if(!found)
    cout << "No such animal exists";

I know this looks like a lot of work for a single user input, but is just another way of doing things, plus this is much more flexible approach instead of the hard-coded 'if...else' or 'switch' constructs. Since you are under going a programming course, I guess the focus would be more on logic and uniqueness than efficiency.

Re: Can not enter multiple data into nested while loop

1. Define a structure.
2. Create an array of structures.
3. Read a line from the file and fill the array accordingly.
4. Accept input from the user.
5. Search the array given the input and pull out the required data.
6. Display the data
7. Repeat steps 4 - 6 till the user enters an '='.

Its pretty simple if you know how to do things. Read up 'struct' in your C++ textbook or search for some online tutorials to help you in that aspect.
