All the default settings of JSON Parser can be represented using the JsonParser.Feature enumeration. The JsonParser.Feature.values() will return all the features that are available for JSONParser but whether a feature is enabled or disabled for a particular parser can be determined using the isEnabled() method of JsonParser.
Syntax
public static enum JsonParser.Feature extends Enum<JsonParser.Feature>
Example
import com.fasterxml.jackson.core.*;
import java.io.*;
public class JsonParserSettingsTest {
public static void main(String[] args) throws IOException {
String json = "[{\"name\":\"Adithya\", \"age\":\"30\"}," + "{\"name\":\"Ravi\", \"age\":\"35\"}]";
JsonFactory jsonFactory = new JsonFactory();
JsonParser jsonParser = jsonFactory.createParser(json);
for(JsonParser.Feature feature : JsonParser.Feature.values()) {
System.out.println(feature.name() + ":" + jsonParser.isEnabled(feature));
}
}
