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.

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces).
