Question
In this assignment, re-implement the Media Library applications in C++ and Java, adding serialization by importing the Library from a Json file to initialize the library, and exporting to a Json file to save the library.
Use the file media.json ( http://pastebin.com/0XAiLPsf ) to initialize the Media Library, and export a modified Json file to save the library upon completion of the program.
One approach to completing this assignment is to add constructors to both your MediaLibrary and MediaDescription classes that initialize from Json. For example, your Java MediaDescription class may have a constructor
public MediaDescription(JSONObject jsonObj)
and your MediaLibrary class may have a constructor that initializes the library from a file containing Json. In Java this may be
public MediaLibrary(String jsonFileName)
Each of these classes may contain methods to export to Json. In MediaDescription this may be
public JSONObject toJson( )
And in MediaLibrary this may be
public void toJsonFile(String jsonFileName)
The Java main program would use the MediaLibrary constructor to initialize the library from a file, and call the toJsonFile method to save the library. Similar methods and constructors would exist in theC++ program.
Structure of your Solution Directory
Submit your solution as a Java archive file (jar) of the project directory: Assign3. Grading your project will be done by extracting the jar and executing the project using Ant from the command-line. The project directory should include only the following files, subdirectories and classes:
The Ant directive file build.xml. The build should contain targets for targets, clean, prepare, build.cpp, execute.cpp, and build.java. The execute.java.
media.json
Subdirectory: src for source files. The src directory contains subdirectories for the Java and C++ source files in java and cpp respectively.
Subdirectory classes used to store the compiled Java class files.
This is what I have from previous project... ( https://app.box.com/s/oa36br6edgtwmrefn9tcowzvfah4fxns )
This question needs the following completed:
Properly formated and named solution file. The Assign3 directory should have the files specified above (only) (4 points).
Screen shot showing exection of your solutions. This may be one screenshot for Java and one for C++ (4 points). Same as prior assignment.
Json Import Functionality. Programs are able to import the library from the media.json file. (6 points).
Json Export Functionality. Programs are able to export the media library to Json file (6 points).
