Using root Commands with JSch (ssh)

Question

I can run regular commands like rm /home/user/Desktop/file but when i cannot run root commands.

My intent is to configure a squid service running commands like: apt-get install squid service squid start service

but those commands require superuser authentication.

Does anyone knows how to fix it? Thanks

public void executarComandoSsh(Session session, String comando) {
    try {
        ChannelExec channel = (ChannelExec) session.openChannel("exec");
        ((ChannelExec) channel).setPty(true);
        ((ChannelExec) channel).setPtyType("vt100");
        ((ChannelExec) channel).setXForwarding(true);
        System.out.println("Comando " + comando);
        channel.setCommand(comando);
        channel.setInputStream(null);
        channel.setErrStream(System.err);
        BufferedReader in = new BufferedReader(new InputStreamReader(channel.getInputStream()));

        channel.connect();
        String line = "";

        while (true) {
            while ((line = in.readLine()) != null) {
                System.out.println("-- " + line);
            }
            break;
        }
        channel.disconnect();
        session.disconnect();

    } catch (JSchException | IOException ex) {
        Logger.getLogger(ServidorNegocioImpl.class.getName()).log(Level.SEVERE, null, ex);
    }
}
