![]() ![]() JsonObject provides a Map view to access the unordered collection of zero or more name/value pairs from the model. Table 1 lists the main classes and interfaces in the object model API. These JSON structures are represented as object models using the Java types JsonObject and JsonArray. It is a high-level API that provides immutable object models for JSON object and array structures. The object model API is similar to the Document Object Model (DOM) API for XML. Similarly, the streaming API provides a way to generate well-formed JSON to a stream by writing one event at a time. The streaming model is adequate for local processing where random access of other parts of the data is not required. Application code can process or discard the parser event and ask for the next event (pull the event). This gives a developer more procedural control over the JSON processing. The streaming API provides an event-based parser and allows an application developer to ask for the next event rather than handling the event in a callback. It hands over parsing and generation control to the programmer. The streaming API provides a way to parse and generate JSON in a streaming fashion. However, it is often not as efficient as the streaming model and requires more memory. This programming model is the most flexible and enables processing that requires random access to the complete contents of the tree. ![]() The tree can then be navigated and queried. The object model API creates a random-access, tree-like structure that represents the JSON data in memory. The Java API for JSON Processing ( JSR 353) provides portable APIs to parse, generate, transform, and query JSON using object model and streaming APIs. All popular websites offer JSON as the data exchange format with their RESTful web services. JSON is often used in Ajax applications, configurations, databases, and RESTful web services. Example of JSON representation of an object Switch statement takes user choice as input and calls the correct case related to choice so that correct task can be performed.Listing 1. ![]() Each case contains different functionality. Switch statement is used to create menu driven program because switch statement contains cases. Which statement is specially used for menu driven program in Java? Because only a limited range of characters are allowed, the way in which the input is to be entered is unambiguous.The system is less prone to user error because input is via single key strokes.The two advantage of using menu driven program is – Menu driven program are very user friendly that’s why most applications use this instead of command line input. User can select and enter options displayed on screen as per his/her choice and can do whatever they want to do. What is a menu driven program in Java?Ī menu driven program displays a list of options to take input from user. So let’s know a brief idea about menu driven in Java. Menus are generally a collection of choice in which user can select any choice according to their interest and can perform that particular task. In many applications you must have seen menus. 2.7 How do I exit from a Menu Driven Program?
