问题描述:

I would like to type some text in textfield, and then select a, if a is not available, then select b, finally submit the information.

I just write these code and get no idea what can I do next.

URL page_1 = new URL("https://google.com.hk");

HttpURLConnection urlconnection = (HttpURLConnection) page_1.openConnection();

DataOutputStream data_out = new DataOutputStream(urlconnection.getOutputStream());

DataInputStream data_in = new DataInputStream(urlconnection.getInputStream());

urlconnection.setDoInput(true);

urlconnection.setDoOutput(true);

System.out.println(data_out);

System.out.println(data_in);

System.out.println(urlconnection);

网友答案:

Java won't load the page and execute the JS code it contains like a browser would do. All it will do is load the data sent by the server in the response.

If you want a programmable browser in Java, then look at Selenium or HtmlUnit.
