Java JSON API

Robust and efficient JSON parser and generator that includes line and column tracker for error handling.
Can handle strings as well as streams for parsing and generating.

Requires:

• LupCode Utilities Library

How to use:

String jsonStr = "{\"Hello World\":[{\"Test\":1.2,\"Bye\":null},345,]}";
		
// Automatically detects class needed to parse JSON
JSON<?> autoJson = JSON.parseAutoJSON(jsonStr);
System.out.println(autoJson.toString(true));

// Another example that shows how errors in the JSON data can be handled
try {
	JsonObject jsonObj = JsonObject.parse(jsonStr);
	System.out.println(jsonObj.toString());
} catch(JsonParseException ex) {
	LineColumnTracker lct = ex.getLineColumn();
	if(lct != null)
		System.out.println("Error occurred at line "+lct.getLine()+", column "+lct.getColumn());
	else
		ex.printStackTrace();
}
