Question

I have the following JAVA CODE:

deleteButton.addActionListener((e -> {
int row= table.getSelectedRow();
if (row>= 0) {
String uName = (String) table.getValueAt(selectedRow, 0);
JSONArray array= readJSONFile("sample.json");

for (int i = 0; i < deleteArray.size(); i++) {
JSONObject obj = (JSONObject) deleteArray.get(i);
String username= (String) obj.get("username");
if (uName.equals(currentUName)) {
array.remove(i);
tableModel.removeRow(row);
break;
}
}
}
}));
}

Please make a code that will delete the details on the selected row on the JSON file.
