JSONObject putOpt is a method used to add a key-value pair to the JSONObject. It takes two parameters - key (string) and value (Object) and puts it in the JSONObject.
Example 1: JSONObject json = new JSONObject(); json.putOpt("name", "John"); json.putOpt("age", 25);
In this example, we create a new JSONObject, and add two key-value pairs - "name" with value "John" and "age" with value 25.
Example 2: JSONObject json = new JSONObject(); json.putOpt("country", null);
In this example, we create a new JSONObject, and add a key-value pair - "country" with a null value.
Example 3: JSONObject json = new JSONObject(); String key = null; String value = "Hello"; json.putOpt(key, value);
In this example, we create a new JSONObject, and add a key-value pair - the key is null and the value is "Hello".
Overall, JSONObject putOpt is a simple and useful method for adding key-value pairs to a JSONObject.
