toJSONString

toJSONString is a method used in Java to convert a JSON object or array into its corresponding JSON string representation. It is typically used in JSON serialization, where an object or array needs to be converted to a string format for data storage or transmission.
Here's an example of how toJSONString can be used in Java:
import org.json.simple.JSONObject;
import org.json.simple.JSONValue;

public class Main {
public static void main(String[] args) {
// Create a JSON object
JSONObject jsonObject = new JSONObject();
jsonObject.put("name", "John");
jsonObject.put("age", 30);
jsonObject.put("city", "New York");

// Convert JSON object to string
String jsonString = JSONValue.toJSONString(jsonObject);

// Print the JSON string
System.out.println(jsonString);
}
}

In this example, the JSONObject class from the JSON.simple library is used to create a JSON object. The put() method is used to add key-value pairs to the object. Then, the JSONValue.toJSONString() method is called to convert the JSON object into a string representation. Finally, the JSON string is printed to the console.
Please note that there are various JSON libraries available in different programming languages, and the specific implementation may vary.
