i try to parse JSON array with format from file like this
> [
{
"Absensi": 20,
"Tunjangan Makan": 400000,
"name": "asdasd",
"ID": 1,
"Gaji Total": 5400000,
"Gaji Pokok": 5000000,
"email": [
"asdasd",
"asdas"
]
},
{
"Absensi": 20,
"Tunjangan Makan": 400000,
"name": "jasnen",
"ID": 2,
"Gaji Total": 5400000,
"Gaji Pokok": 5000000,
"email": [
"asdasd",
"asdasda"
]
}
]
here is my code:
public static void readJsonFileManager(String file) throws ParseException, FileNotFoundException, IOException{
JSONParser parser = new JSONParser();
Reader reader = new FileReader(file);
Object jsonObj ;
jsonObj = parser.parse(reader);
JSONObject jsonObject = (JSONObject) jsonObj;
while(jsonObj != null) {
long ID = (long) jsonObject.get("ID");
System.out.println("ID = " + ID);
String name = (String) jsonObject.get("name");
System.out.println("Name = " + name);
long Absensi = (long) jsonObject.get("Absensi");
System.out.println("Absensi = " + Absensi);
long GajiPokok = (long) jsonObject.get("Gaji Pokok");
System.out.println("GajiPokok = " + GajiPokok);
long GajiTotal = (long) jsonObject.get("Gaji Total");
System.out.println("GajiTotal = " + GajiTotal);
long Tunjangan = (long) jsonObject.get("Tunjangan Makan");
System.out.println("Tunjangan Makan= " + Tunjangan + "\n");
jsonObj = parser.parse(reader);
}
But when i run it it show error bracket on my terminal is there something wrong with my code, i cannot find any post relate to my problem??
Exception in thread "main" java.lang.ClassCastException: 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')

Instead of taking it in JSONObject
, parse it in JSONArray
.
JSONArray array = new JSONArray(jsonObject);
while (array.hasNext()) {
JSONObject obj = array.next();
System.out.println(obj.get("ID"));
}
