getting TreeSet object from Object variable

I've a Object val with values [0,2,4,5,9], actually these values are been created from TreeSet like as shown below

TreeSet ts=new TreeSet ();
ts.add(0);
ts.add(2);
ts.add(4);
ts.add(5);
ts.add(9);

System.out.println(ts);

Output

[0,2,4,5,9]

i'm passing the output as string from server to client side

in the client side i 've

Object obj="[0,2,4,5,9]";

Can anyone please tell me how to convert the object values [0,2,4,5,9] to TreeSet Object so that i can iterate the values

Solution

  • You can send the treeset value back to the client in the form of JSONArray. I would recommend you to look into org.json package to easily do these kind of client and server interaction.

    Note : JSON is light-weight data interchange format than xml. Latest browsers support json as a defacult standard. if you further want to go for string based value, you have to make use of javascript function to split the values and make use of them
