Understanding of encryption part from source code

hello guys

i need your help in something
i'm trying now with a java program .i dont have the source code .i need to get it to run.
i found some strings in the classes that seems to be some sort of encrypted text,even i'm sure it is some sort of encrypted text .
i need your help to point out me on how to know what sort of encryption has been used in it ,or may be you know what it is .
the code seem to be addressing a URL and i need to know it and how to change it
please try to have a look at it and tell me i need to crack this encrypted text and change it.

Code :

the strings in red are the one that i think encrypted
if you guys need any further code tell me
thank you in advance

I'm not so sure about this one, what are your intentions exactly?

If you don't have the source how do you intend to change the URL in the actual code?

// Json

i can edit it with any hex editor
here is another part of the code that i think it might help

Code :

---

 private static String w(String s1, String s2)
    {
        s1 = new URL(s1);
        s1 = new DataInputStream(s1.openStream());
        String s3;
        for(s3 = ""; s3.toLowerCase().indexOf(s2) < 0; s3 = s1.readLine());
        s1 = (s1 = Pattern.compile("(\\d{1,3}\\.){3}\\d{1,3}")).matcher(s3);
        s2 = "";
        if(s1.find())
            s2 = s1.group();
        u_java_lang_String_static_fld = s2;
        return s2;
    }
 
    public static String ar()
    {
        if(u_java_lang_String_static_fld != null)
            return u_java_lang_String_static_fld;
        String s1;
        try
        {
            if((s1 = w(s1 = ChatServer.q("ec3[[\"80\\\026#d/D\026 z>\006\b}9$D\f"), "title")) == null || "".equals(s1))
                throw new Exception();
            else
                return s1;
        }
        catch(Exception _ex) { }
        try
        {
            if((s1 = w(s1 = ChatServer.q("ec3[[\"80\\\026#g5D\031ts\"_\004nciH\016`"), ChatServer.q("tx2YAdggJ\005ie\"X\022"))) == null || "".equals(s1))
                throw new Exception();
            else
                return s1;
        }
        catch(Exception _ex) { }
        try
        {
            if((s1 = w(s1 = ChatServer.q("ec3[[\"80\\\026#~7\006\000ie\"X\022#t(F"), ChatServer.q("`ngB\021-v#O\023hd4\021"))) == null || "".equals(s1))
                throw new Exception();
            else
                return s1;
        }
        catch(Exception _ex)
        {
            return "";
        }
    }

I don't recognise that encryption.

If you don't have all the source code, then what are you looking to do with this exactly?

Are you wanting to run this with your own URL or are you looking to find out what the encrypted URL is?

thanks for response
actually both ; i need first to know what it is calling and what is the url
and then i'll see if i can change it to work with mine or anything i choose .
as i read it might be some sort of serialized method .i thought you guys might help me out.
anyway if some one can i'll be very thankful as i'm working on it since two months.
thanks in advance.
