Thanks a lot David,
I was doing the same thing, i.e, iterating the 1st array and putting the value in the 2nd one. this method does it more neatly.

BTW, this is ok for arrays, but what if its not an array? then is it possible to do what i asked for?

Hi,

I have this code:
ArrayList a1 = new ArrayList(); ArrayList a2 = new ArrayList(); a1.add("1"); a1.add("2"); a1.add("3");
Now I want a copy of a1 assigned to a2, but the original a1 will not be affected, so if I remove an element from a2, from a1 it won't remove.

I don't want to use clone. Is there any way to do that?

Kindly help.

Advance thanks, imran

Scenario:
I'm populating a hashtable by taking values from 2 columns of a csv file. Now, I want to write the key/value into a properties file with some formatting, such as:
<code>
key = value;
</code>
I'm having problem in writing into the file as I want to loop through the hashtable until it ends, and taking the key/value pair from it.

Please suggest mer hoe to do that.

Hi,

I want to know is it possible to set the values in a properties file thru java program?
The scenario is like this: i'm getting 2 or more product id's from xml. Now i've to display a proper message where that 2 product_id will be inserted. The message is already defined in the properties file as a template. Now i've written the properties file like this:
product1 = 1234567 product2 = 8223232 template1 = Product {0} was replaced by {1} due to something. template2 = Product {0} is blah blah and product {1} will be blah blah.
That product1 & product2 value should come from xml.How can i do this?

Another thing is that,i'm using eclipse and its giving error:
java.util.MissingResourceException: Can't find bundle for base name MessageBundle, locale en_US at java.util.ResourceBundle.throwMissingResourceException(Unknown Source)
Where i've to keep the properties file? i've tried keeping it at the same place where java files are residing, in a different folder outside the package...but its giving the same error...

please help

My friend has a situation: a jsp page having links to different project specific details. When user clicks on any link it will fetch the related details from the DB and should show that in the same page. He's stuck in the thing that it has to be shown in the same page.

Please suggest.

Regards.

HI,

I'm trying to connect with oracle installed in different machine. I've oracle client installed in my machine. So i'm writing like this:

import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class NewConnection { static Connection con=null; public Connection getConnection(){ try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); con=DriverManager.getConnection("Jdbc dbc:abcd","scott","tiger"); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return con; } }
abcd is the dns name.
My question is what i've to pass as parameter in the getConnection() method if the other machine has ip: 10.124.12.148 and port:8081.?

Just do:

int x=0;
char c='a';

x=c;


You can always convert a char, byte or short into an int without explicit casting, because they're widening conversion.

Hi Ranchers,

I want to read a csv file and separate out and store in String each comma separated values. I am stuck at reading a single line at a time. Can anybody please show me a piece of code to do these?

Thanks

Thanks,

I used strategy pattern and its working nicely.

A scenario occurred like this:
3 classes: Bat, Eat, Fat. When Bat is instantiated only Bat related methods are called. When Eat is instantiated Eat+ Bat related methods are called. When Fat is instantiated Fat+Eat+Bat (means all) methods are called.

Bat & Eat are language specific & there are nine languages. So, nine Bat & nine Eat. But, Fat is not language specific, there's only one Fat. Now, the question is how it can be designed so that when suppose french is passed as language parameter Bat_fr+Eat_fr+Fat specific methods will be called.

I thought of making Bat as interface which will be extended by Eat interface & which will be implemented by Fat. Don't know if it is ok.

Kindly guide me.

Imran
