First you need to convert the String to JSON and parse it, you can use org.json to do it, more details can be found at How to convert String to JSONObject in Java

JSONObject jsonObj = new JSONObject("{\"phonetype\":\"N95\",\"cat\":\"WP\"}");

Then you need to download the data URL,more details can be found at How to download and save a file from Internet using Java?

URL website = new URL("http://www.website.com/information.asp");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream("information.html");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
