> I have a string like> String str = "abc";What value would abc represent? Is it hex or a number in another base?Take a look at Integer.parseInt(String s, int radix) Kaj

So into what integer value should "abc" be converted ?

You might check [url=http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#hashCode()]String.hashCode()[/url] or [url=http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Integer.html#parseInt(java.lang.String, int)]Integer.parseInt(String s, int radix)[/url].

yes..thanks, but is it possible to reconvert the same int or integer value to the string..for eg..if i convert a string "str" to some int value say i..is it possible to get the string "abc" from value i?

I'm afraid there are more possible Strings than possible integer values. So, I would say no, this is not possible.

Oh..no..Actually my problem is that, i have to pass "#" symbol for one of the values in query parameter.. while passing so, after this parameter none of the other parameters are considered..how to handle this? any idea?

I am sending a request that contains multiple request parameters.

for one of the parameters iam sending a value as "#". if i send so, other parameters are not considered.

for eg..

http://localhost:8080/cs?query=#&name="me" -- if i send like this, name parameter is not considered..since # represents the current page.. got my problem?

I'm not a web developer, but I think you should encode the url. # will become %23Kaj

yes u r rite..but iam not sending the request as part of url..hence the prob...

Why do you need to change a String object to int if you just need to check whether it is "#" or not ?or they are 2 unrelated questions ?

yes those r related..first i thought of checking whether its "#" as you said. i doubted whether someother special character will affect in same way..so thought of converting the parameter value(such as "#'' or "abc") to ASCII value and send the same as request parameter..

TryString encoded = java.net.URLEncoder.encode("abc#def", "UTF-8");

It works fine..i think we can avoid the encoding type, rite?just single parameter encode() method should work fine.

why should not?by default IE, takes encoding type as "UTF-8"na?
