of("Mahesh", "Krishna", "Brahma"); JSONArray jsonArray = new JSONArray(list); System.out.println(jsonArray.toString()); Output ["Mahesh","Krishna","Brahma"] Example-2: Instantiating JSONArray using String array. String[] ar = {"Mahesh", "Krishna", "Brahma"}; JSONArray jsonArray...
This example uses the JSON file fruit_array.json. The following shows the contents of the file fruit_array.json: Copy [{"name" : "apple", "count": 20 }, {"name" : "orange", "count": 42 }, {"name" : "pear", "count": 10 }] Before loading data into Autonomous Database, ...
For an example of how these class methods are used to parse an array from a JSON string and convert it into a JsonArray object, update the values the array contains, and then serialize the updated JsonArray object as a JSON string, see Using JavaScript Object Notation (JSON). Enumerating ...
, sid)); //pool.setMaximumPoolSize(5); // Processing these new schedules takes all kinds of memory! if (ids.length() == grabOpts.getMaxSchedChunk()) { pool.execute(new ScheduleTask(ids, vfs, clnt, progCache, factory)); ids = new JSONArray(); } } if (ids.length() > 0) ...
It also provides an unmodifiable list view of the values in the array. A JsonArray object can be created by reading JSON data from an input source or it can be built from scratch using an array builder object. The following example demonstrates how to create a JsonArray object from an...
