How to download WordPress with Java -

i want download wordpress java.

my code looks this:

public void file(string surl, string pathtosave) throws ioexception {     url url = new url(surl);     sun.net.www.protocol.http.httpurlconnection con = (httpurlconnection) url.openconnection();     try (inputstream stream = con.getinputstream()) {         files.copy(stream, paths.get(pathtosave));     } } 

i using url download latest version of wordpress: http://wordpress.org/latest.tar.gz

but when try extracting tar.gz file error saying file not in gzip format.

i read issues uncompressing tar.gz file , looks when download wordpress need have cookie enabled accept terms , services.

how this?

or incorrectly downloading tar.gz file?

here tar.gz extracting code:

public class unzip { public static int buffer = 2048; public void tar(string pathtotar, string outputpath) throws ioexception {     file tarfile = new file(pathtotar);     tararchiveinputstream tarinput =             new tararchiveinputstream(new gzipinputstream(new fileinputstream(tarfile)));      tararchiveentry currententry = tarinput.getnexttarentry();     while(currententry != null) {         if (currententry.isdirectory()) {              file f = new file(outputpath + currententry.getname());             f.mkdirs();         }         else {             int count;             byte data[] = new byte[buffer];              fileoutputstream fos = new fileoutputstream(outputpath                     + currententry.getname());             bufferedoutputstream dest = new bufferedoutputstream(fos,                     buffer);             while ((count = tarinput.read(data, 0, buffer)) != -1) {                 dest.write(data, 0, count);             }             dest.close();         }     } } 

}

thanks in advance.

1. change sun.net.www.protocol.http.httpurlconnection java.net.httpurlconnection

2. add fos.close() after dest.close()

3. you must call currententry = tarinput.getnexttarentry(); inside while loop, too.

there nothing cookie enabled or accept terms , services.

here complete code. please try , compare code:
