How to decode an object via URL?

Question

I have the object URL and I needed to encode and then de-perform, how do I do that? The URL is from a server that displays a Java object encoded and serialized.

This may help you. This code opens an HTTP connection and downloads the content. After that, you should only decode the result. If this doesn’t fit, please explain better what you’re trying to do.

package testes;

import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class DownloadURL {
    public static void main(String[] args) throws IOException {
        HttpURLConnection c1 = (HttpURLConnection) new URL("http://grepcode.com").openConnection();
        int code1 = c1.getResponseCode();
        InputStream resposta = code1 >= 400 ? c1.getErrorStream() : c1.getInputStream();

        System.out.println(code1);
        StringBuilder sb = new StringBuilder(10240);
        int r;
        while ((r = resposta.read()) != -1) {
            sb.append((char) r);
        }
        System.out.println(sb);
    }
}
