Thanks @Kit Ho for your answer. I used your code and found that I kept running into errors where my InputStream was always null and ClassNotFound exceptions when the JSONObject was being created. Here's my version of your code which does the trick for me:
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;
import org.json.JSONObject;
public class JSONParsing {
public static void main(String[] args) throws Exception {
File f = new File("file.json");
if (f.exists()){
InputStream is = new FileInputStream("file.json");
String jsonTxt = IOUtils.toString(is, "UTF-8");
System.out.println(jsonTxt);
JSONObject json = new JSONObject(jsonTxt);
String a = json.getString("1000");
System.out.println(a);
}
}
}
I found this answer to be enlightening about the difference between FileInputStream and getResourceAsStream. Hope this helps someone else too.
