Parsing a String

[anees ahamed]

Hi all,
Let me first say that I have posted this in sun forums and it didnt work out for me.
I am reframing my question here for your valuable suggestions and comments.

This is the general format in which I get data from database(This is an example where the group names and user names are variables and the other syntax will be exactly the same). Literally I do not know what kind of string is this and what to do with this.

{groups:['TestG','test'],contacts:[{usr:'test10',group:'TestG'},{usr:'rhar',grou\p:'TestG'},{usr:'zapata31',group:''},{usr:'pertchiou',group:''}]}

I need an output of the format

[Group name1,users of this group]
[Group name2,users of this group] 
 
and so on.

For users with no groups, it should be

[No Group,users having no groups]

I would like to have these outputs in some array or as any collection
in Java. How can I accomplish this?

For a not so difficult string parsing algorithm, Scanner proves useful.

Try it out and let us know whether you got what you desired

[arulk pillai]

Write a simple parser to convert it to the format you want it in.

Regex can be useful

It looks like JSON. There are a number of Java libraries available to parse JSON, they are listed on the website.

What's not so nice is continuing the topic on the other forum even after posting here, not mentioning the cross post on the other forum, and not providing a link.

I think DB is correct; everybody posting ought to know about other discussions. Read this FAQ.

I got it solved,
For anyone having future use, this is how I solved.

import org.json.JSONObject;
public class JsonTest {
public static void main(String args[]){
String s = "{groups:['TestG','test'],contacts:[{usr:'test10',group:'TestG'},{usr:'rhar',group:'TestG'},{usr:'zapata31',group:''},{usr:'pertchiou',group:''}]}";
JSONObject arr;
try {
arr = new JSONObject(s);
System.out.println(arr.get("groups"));
System.out.println(arr.get("contacts"));
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
 

which gave me the output

["TestG","test"]
[{"usr":"test10","group":"TestG"},{"usr":"rhar","group":"TestG"},{"usr":"zapata31","group":""},{"usr":"pertchiou","group":""}]
