  \"reviewerID\": \"A2XVJBSRI3SWDI\", 
  \"asin\": \"0000031887\",

In case you need to parse it from a file, I find the best solution to use a HashMap to use it inside your java code for better manipultion.

Try out this code:

public HashMap myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}
