This is what i have tried
try {
obj = new JSONParser().parse(new FileReader("jsonExampl.json"));
JSONObject jo = (JSONObject) obj;
empid = (String) jo.get("EmployeeId");
firstname = (String) jo.get("FirstName");
lastname = (String) jo.get("LastName");
DOB = (String) jo.get("DOB");
String ae = (String) jo.get("Age");
System.out.println("Employee Id:- "+ empid);
System.out.println("First Name:- "+ firstname);
System.out.println("Last Name:- "+ lastname);
System.out.println("DOB:- "+ DOB);
System.out.println("Age:- "+ ae);
Map address = ((Map)jo.get("Address"));
Iterator<Map.Entry> itr1 = address.entrySet().iterator();
while (itr1.hasNext()) {
Map.Entry pair = itr1.next();
System.out.println(pair.getKey() + " : " + pair.getValue());
phnumber=(String) jo.get("PhoneNumber");
personalemail = (String) jo.get("PersonalMail");
officialemail = (String) jo.get("OfficialMail");
department = (String) jo.get("Department");
DOJ = (String) jo.get("DOJ");
Education = (String) jo.get("Education");
System.out.println("Employee Phone:- "+ phnumber);
System.out.println("Personal:- "+ personalemail);
System.out.println("Official:- "+ officialemail);
System.out.println("DOJ:- "+ DOJ);
System.out.println("Education:- "+ Education);
} catch (Exception e) {
// TODO: handle exception
System.out.println(e.getMessage());
The code is not working when I try to parse the json array, so I get:
class org.json.simple.JSONArray cannot be cast to class org.json.simple.JSONObject (org.json.simple.JSONArray and org.json.simple.JSONObject are in unnamed module of loader 'app')
Please help
Thank you in Advance

You have to parse it to JSONArray as in the comment above. This is the fixed code:
JSONArray array = (JSONArray) new JSONParser().parse(json);
for(Object obj : array.stream().toArray()) {
JSONObject jo = (JSONObject) obj;
String empid = (String) jo.get("EmployeeId");
String firstname = (String) jo.get("FirstName");
String lastname = (String) jo.get("LastName");
String DOB = (String) jo.get("DOB");
String ae = (String) jo.get("Age");
System.out.println("Employee Id:- " + empid);
System.out.println("First Name:- " + firstname);
System.out.println("Last Name:- " + lastname);
System.out.println("DOB:- " + DOB);
System.out.println("Age:- " + ae);
