How to convert jsonString to JSONObject in Java

To convert a JSON string to a JSONObject in Java, you can use the JSONObject constructor that takes a String as an argument, like this:

String jsonString = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
JSONObject jsonObject = new JSONObject(jsonString);

You can then access the values in the JSONObject using the get method, like this:

String name = jsonObject.getString("name");
int age = jsonObject.getInt("age");
String city = jsonObject.getString("city");

Alternatively, you can use a org.json library to parse the JSON string. Here's an example using the org.json library:

String jsonString = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
JSONObject jsonObject = new JSONObject(jsonString);

String name = jsonObject.getString("name");
int age = jsonObject.getInt("age");
String city = jsonObject.getString("city");
