Well, I did that. Anyway thank you.
I have a different but related doubt. You can only read key-value pairs
from a properties file. In case if there are two or three simple values
(instead of just one in properties file) for every key, how can you store
and read from a simple file (possibly a text file ?) (without going for
tables/database). This has to be loaded in a right data structure and has
to be retrieved.
Say for example, id=1,kevin,23
id=2,mukar,32
Please tell me the following approach is right ?
Read it as a properties file and after that by using StringTokenizer "," ,
we can get the individual values.
Is there any other better approach ?
Regards
Raj

Have you read the javadoc for Properties and Hashtable yet? Normally that
should
be enough to answer your question. If you have read the docs, are you having
a
specific problem?
First create property file using an editor
Here's pseudo code showing one way to get properties:
create instance of java.io.FileInputStream from property file
create instance of java.util.Properties
call Properties.load(InputStream) method to load properties
call Properties.propertyNames() to get Enumeration of all names
loop through Enumeration of names
call getProperty(name) to get a property
if you really want to, store name/property in hashtable
Why are you wanting to store the properties in a Hashtable? Since the
Properties
class already stores properties for you using a key-value approach, creating
a
Hashtable to store the properties is redundant.
