    Do not use regex. Use a JSON parser. Commented Apr 14, 2015 at 7:09
  • I suggest you take a look at the org.json library (import org.json.*) rather than using regex. Commented Apr 14, 2015 at 7:10
  • Thanx for quick reply i alredy tried with json parser but i got left '[ ' error Commented Apr 14, 2015 at 7:10

Use a JSON parser:

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class SOPlayground {

    public static void main(String[] args) throws Exception {
        String j = "{\n"
                + "    \"Title\": \"nice television for the price\",\n"
                + "    \"Author\": \"Jackie C\",\n"
                + "    \"ReviewID\": \"R3LDJA7HU2Q0FS\",\n"
                + "    \"Overall\": \"4.0\",\n"
                + "    \"Content\": \"The television was a refurbished one, and for the price, quality of pictures, sound, i am enjoying it at this very moment. I'm glad that I made a good choice thus far without having any problems with the television.  Thanks\",\n"
                + "    \"Date\": \"April 13, 2014\"\n"
                + "}";

        JSONParser p = new JSONParser();
        JSONObject o = (JSONObject) p.parse(j);
        System.out.println(o.get("Title"));
    }
}

Output:

nice television for the price
