how to read Json Array file and pass it as a function arguments for testing the function n java

here i need to pass the properties argument to the below function.
my function is below:
public static void convertDateAttrsToString(JSONArray properties, BasicDBObject attributesObj) {
if (properties != null && !properties.isEmpty()) {
for (Object property1 : properties) {
JSONObject property = (JSONObject) property1;
if (attributesObj.containsField(attributeId)) {
BasicDBObject attribute = (BasicDBObject) attributesObj.get(attributeId);
if (attribute.getString(Constants.CONSTANT_DATATYPE).equals(Constants.CONSTANT_DATE)) {

FileReader reader = new FileReader(resource.getFile());

// Read JSON file
Object obj = JsonParser.parseList();

JSONArray infoList = (JSONArray) obj;
