jsonparser

parses JSON, returns a Java object parse tree

Instructions:

1. Execute "javac jsonparser/*.java" from root directory of repository

2. Add the statement "import jsonparser.Parser;" to your Java source file

3. Create a Parser object

   • "Parser parser = new Parser();"

4. Call the parse method of the Parser object on a File object or a String object

   • parser.parse(new java.io.File("path/of/your/json/file"));
   • parser.parse("{\"key1\" : \"value1\", \"key2\": \"value2\"}");
     • Note: you must escape JSON string literals

5. parser.parse returns root of the parse tree, which is a JsonElement

   • JsonElement is a superclass of the following classes:
     • JsonObject
     • JsonArray
     • JsonString
     • JsonNumber
     • JsonBoolean
     • JsonNull

6. Call the corresponding method for each class, listed below, to get the underlying object

   • JsonObject - Map<String, JsonElement> getMap()
   • JsonArray - List getList()
   • JsonString - String getString()
   • JsonNumber - Double getDouble()
   • JsonNull - none
   • JsonBoolean - Boolean getBoolean

7. With the methods above you can traverse the tree and get the data from a node
