Processing JSON Data - Java - page 780

public public static void main ( String [] args ) {

LocalDate dNow = LocalDate . now ();
System . out . println ( toJson ( dNow ));

static void

}

public public static static String toJson ( LocalDate dNow ) {

StringBuilder sb = new new StringBuilder ();

sb . append ( OPEN ). append ( "\n" );
sb . append ( jsonize ( "year" , dNow . getYear ()));
sb . append ( jsonize ( "month" , dNow . getMonth ()));
sb . append ( jsonize ( "day" , dNow . getDayOfMonth ()));
sb . append ( CLOSE ). append ( "\n" );
return return sb . toString ();

}

public public static static String jsonize ( String key , Object value ) {

return

return String . format ( "\"%s\": \"%s\",\n" , key , value );

}

}

Of course, this is an extremely trivial example. For anything more involved, or for the com-
mon case of having to parse JSON objects, using one of the frameworks will be easier on
your nerves.

Parsing and Writing JSON with Jackson

Problem

You want to read and/or write JSON using a full-function JSON API.

Solution

Use Jackson, the full-blown JSON API.
