You need to specify 'checked' to keep its state, e.g.

<input type="checkbox" name="foo" value="bar" checked>

This page has a good explanation: http://www.pathname.com/fhs/pub/fhs-2.3.html

I wonder if anyone knows any *generic* method that loops through 2 instances of the same class and find the difference in terms of their fields.

What would such a method return? The diff(...) method in your example is void. You could have an equals method that uses reflection (I think EqualsBuilder from Jakarta commmons does something like that).

try

Help - Software updates - Find and install...

Add new remote site http://eclipse-javacc.sourceforge.net

etc..

Look at line 7:

07: String locObj = anObj;

The string is still reachable through the locObj reference. Line 11 is correct because all objects become unreachable beyond the if statement.

To parse TCP header information, the base class would have to know about its child.

A base class should not be aware of its subclasses. If it is, then you should consider refactoring your design.

You could use a regular expression.

String input = "FC5_P1595_PBUF0034_P1595_FC6"; Pattern pattern = Pattern.compile("(.*)_(.*)_(.*)_(.*)_(.*)"); Matcher matcher = pattern.matcher(input); for(int i=1; matcher.matches() && i <= matcher.groupCount(); i++) { System.out.println(matcher.group(i)); }

There's a better way to represent a repeating group, but i can't recall how to do this off top of my head.

Or you can download SLOC count. It supports different languages, easy to use and does everything for you.

Thanks. Will give it a try.

I had exactly the same problem. In my case it was because of my laptop's touch pad. I didn't bother changing anything though. Once you get used to it, it stops happening.

Try giving eclipse more memory. You can do this by modifying default values in eclipse.ini file.

Login with postgres as the username and create a new user:

$ psql -d template1 -U postgres # CREATE USER myUsername WITH PASSWORD �myPassword�;

This page will help if you get stuck.

I don't want to actually read all the rows. I just need to know how many there are

If you don't need the data, you could do a select count:

select count(widget_id) as num_widgets from widgets;
