net.sf.jsonobject的accumulate方法
The 'accumulate' method in 'net.sf.json.JSONObject' is used to add a key-value pair to the JSON object. Syntax: public JSONObject accumulate(String key, Object value)Parameters:- key: The key to associate with the value.- value: The value to be added.Return value:- The updated JSON object.Example usage:import net.sf.json.JSONObject;public class Example {  public static void main(String[] args) {    JSONObject jsonObject = new JSONObject();        Add key-value pairs using accumulate method    jsonObject.accumulate("name", "John");    jsonObject.accumulate("age", 30);        System.out.String());  }}Output:{"name":"John","age":30}In the example above, we create a new JSONObject and use the 'accumulate' method to add two key-value pairs: "name" with value "John" and "age" with value 30. The 'toString' method is used to convert the JSONObject to a string representation, which is then printed to the console.
