How do I log in to the token method?

public static void main(String[]args)throws Exception {


    String USER_AGENT = "Mozilla/5.0";
    String url="https://www.lancers.jp/user/login";
    String user="https://www.lancers.jp/mypage";
    HttpGet=new HttpGet(url);
    HttpPost post = new HttpPost(url);

    RequestConfig requestconf = RequestConfig.custom()
            .setCircularRedirectsAllowed(true)
            .setRedirectsEnabled (true)
            .build();
    List<Header>headers=new ArrayList<Header>();
    headers.add(new BasicHeader("User-Agent", USER_AGENT));
    heads.add(new BasicHeader("Accept-Charset", "utf-8"));
    headers.add(new BasicHeader("Accept-Language", "ja,en;q=0.8"));
    headers.add(new BasicHeader("Content-Type", "application/x-www-form-urlencoded"));

    CloseableHttpClientclient=HttpClientBuilder.create()
            .setRedirectStratey (new LaxRedirectStratey())
            .setDefaultRequestConfig(reqconf)
            .setDefaultHeaders (headers)
            .build();

    CloseableHttpResponse loginpage=client.execute(get);
    String loginpageHTML = EntityUtils.toString(loginpage.getEntity(), "UTF-8");
    // Even if it's Jsoup or something like that, it seems impossible to parse Token only, so I searched manually...
    Pattern p=Pattern.compile("(?is)value=\"(.+?)\"); 
    Matcher m=p.matcher (loginpageHTML);
    // Look for tokens.
    String [ ] TokenArray=new String[6];

    inti = 0;
    while(m.find()){
        TokenArray[i]=m.group((1));
        i++;
    }
    // TokenArray[1] TokenArray[5]
    // 1 is key, 5 is fields. Let's include this in the POST transmission.

    List<NameValuePair>params=new ArrayList<NameValuePair>();;
    params.add(new BasicNameValuePair("data[_Token][key])", TokenArray[1]);
    params.add(new BasicNameValuePair("data[User][email]", "My ID"));
    params.add(new BasicNameValuePair("data[User][password]", "My PASS"));
    param.add(new BasicNameValuePair("data[User][auto_login]", "0"));
    param.add(new BasicNameValuePair("data[User][refer]", "http://www.lancers.jp/"));
    params.add(new BasicNameValuePair("data[_Token][fields]", TokenArray[5])));

    post.setHeader("Connection", "keep-alive");
    post.setHeader("Refer", user);
    post.setHeader("Content-Type", "application/x-www-form-urlencoded";

    post.setEntity (new UrlEncodedFormEntity (params));

    String html="";
    CloseableHttpResponse response=client.execute(post);

    try{
    HttpEntity entity=response.getEntity();
    html=EntityUtils.toString(entity, "UTF-8");
    EntityUtils.consume(entity);
    }finally {
        response.close();
    }

    Document doc = Jgroup.parse(html);
    System.out.println(doc);
