I want to update SName, ZipCode,taxAmount,Quantity, and text[1] values are there any way to do this.我想更新 SName、ZipCode、taxAmount、Quantity 和 text[1] 值有没有办法做到这一点。 I am taking JSON in a file and update tags are taking into HashMap
我将 JSON 放入文件中,并且更新标签正在使用 HashMap
JSONObject jsonObject = new JSONObject("Your_JSON_String");
JSONObject jsonObjectForState = jsonObject.getJSONObject(“State”);
jsonObjectForState.put("Sname", "New_Value_Here");
put(...)
will replace the current value with new value. put(...)
将用新值替换当前值。 Similarly, you can update the other values.同样,您可以更新其他值。 Once you are done, you can convert it back using:
完成后,您可以使用以下方法将其转换回:
jsonObject.toString();
And write it back to the file.并将其写回文件。
