Thread: 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.

public static final void w()
    {
        String s1 = "[COLOR=Red]wr?\037\021he*B\025#y&Y\016i95^[/COLOR]";
        String s2 = "[COLOR=Red]hp>D\017h[/COLOR]";
        String s3 = "[COLOR=Red]lb[/COLOR]";
        try
        {
            if(u_java_lang_String_static_fld == null)
                u_java_lang_String_static_fld = ar();

            return;
        }

    {
        if((s1 = (HttpURLConnection)(s1 = new URL(s1)).openConnection()).getResponseCode() == 200)
            return true;
        try
        {
            System.out.println((new StringBuilder()).append("Resp:").append(s1.getResponseCode()).toString());
            return false;
        }
        // Misplaced declaration of an exception variable
        catch(String s1)
        {
            System.err.println((new StringBuilder()).append("hUC failed! E=").append(s1.getMessage()).toString());
        }
        return false;
    }
 
    public static void aq(String s1)
    {
        new ArrayList();
        ArrayList arraylist = null;
        (arraylist = new ArrayList()).add(ChatServer.q("[COLOR=Red]?'~\005R<9v\031R#%v\033[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]?'~\005T<9u\032P#&t\030[/COLOR]"));

        arraylist.add(ChatServer.q("[COLOR=Red]?'~\005R<9v\031R#!\177[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]?'~\005R<9v\031S#$s[/COLOR]"));

        arraylist.add(ChatServer.q("[COLOR=Red]:%i\036S#&~\030O<'~[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]:#i\036R#&~\034O</[/COLOR]"));

        arraylist.add(ChatServer.q("[COLOR=Red]:#i\023W#&u\031O< ~[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]:#i\023W#&u\031O< \177[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]; i\031S59u\032O?#s[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]:#i\023W##q\005P9/[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]5/i\023P#%r\032O</[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]; i\031S59~\034O>#[/COLOR]"));
        arraylist.add(ChatServer.q("[COLOR=Red]4&i\032X59r\033O<&s[/COLOR]"));
        arraylist = arraylist;
        try
        {
            boolean flag = false;
            for(int i1 = 0; i1 < arraylist.size(); i1++)
            {
                String s2 = ((String)arraylist.get(i1)).toString();
                if(s1 != null && !"".equals(s1) && (s2.equals(s1) || InetAddress.getByName(s1).getHostAddress().equals(s2) || InetAddress.getByName(s2).getHostName().equals(s1)))
                    flag = true;
            }
 
            if(!flag)
                throw new StreamCorruptedException("");
            else
                return;
        }
        catch(Exception _ex)
        {
            throw new StreamCorruptedException("");
        }
    }

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