I have been trying to use Java ProcessBuilder to execute youtube-dl with parameters.
I have not been able to pass more than one parameter to youtube. Tried to enter one parameter after another as this:

`for (int i = 0; i < links.length; i++) {

//youtube dl commands
String path = "G:\\youtube-dl.exe";
String ea = "-x";
String af = "--audio-format mp3";
String aq = "--audio-quality 75K";
String[] cmd = {path, ea, af, aq, links[i]};
ProcessBuilder process = new ProcessBuilder(cmd);
String output = org.apache.commons.io.IOUtils.toString(process.start().getErrorStream());
System.out.println(output);
process.start();

}`
But it only passed the first one, then said

error: no such option --audio-format mp3

Then I tried to pass it as one big command
String commands = "--extract-audio" + "--audio-format " + defaultAudioFormat + "--audio-quality " + aBitrate + "K";
and i got the same result, but every command there

error: no such option: --extract-audio--audio-format mp3--audio-quality 75K

Adding spaces in quotes does not work.
Would you happen to know how can I get it to work?

String[] cmd = {path, ea, "--audio-format", "mp3", links[i]};
