Then the new code decodes the strings into JSONObject objects using a parse method from the JSONParser class and saves them in a fourth ArrayList object.

The contents of both lists of JSONObject objects are displayed on the computer screen after they are populated with decoded data fromthe JSON strings.

Decode and display using the JSONValue class

I will explain this program in fragments, and will begin at the point where the new code begins. The first fragment is shown in Listing 1 .

Listing 1 . Decode and display using the JSONValue class. //Create a container for decoded JSON strings. ArrayList<JSONObject>listC = new ArrayList<JSONObject>(); //Decode and display JSON strings using the parse method of the// JSONValue class System.out.println("Decode using JSONValue class");decodeC(listB,listC); display(listC);System.out.println();//blank line

Immediately prior to the code in Listing 1 , three JSON strings are stored as elements in an ArrayList object referred to as listB .

Listing 1 begins by instantiating a new ArrayList object, referred to as listC that will receive the decoded versions of the JSON strings as type JSONObject objects. Then Listing 1 calls the method named decodeC passing the list of JSON strings and the empty list as parameters.

The method named decodeC

The method named decodeC is shown in its entirety in Listing 2 .

Listing 2 . The method named decodeC. static void decodeC(ArrayList input,ArrayList output){ String temp = null;Iterator<String>iterator = input.iterator(); while (iterator.hasNext()){temp = iterator.next(); output.add(JSONValue.parse(temp));}//end while loop }//end decodeC

This method decodes a list of JSON strings into JSONObject objects using a static parse method of the JSONValue class. The resulting JSONObject objects are added to the empty ArrayList object received as an incoming parameter. When the method returns, that list contains one JSONObject object for each JSON string contained in the incoming ArrayList object.

Display contents of JSONObject objects

Returning now to the code in Listing 1 , the next statement calls the display method passing the now-populated listC as a parameter. At this point, the JSONObject objects stored in listC contain the information that was extracted from the JSON strings by the parse method of the JSONValue class.

The display method is shown in its entirety in Listing 3 .

Listing 3 . The display method. static void display(ArrayList input){ JSONObject temp = null;Iterator<JSONObject>iterator = input.iterator(); while (iterator.hasNext()){temp = iterator.next(); System.out.print("Name: " + temp.get("name"));System.out.print(" Age: " + temp.get("age")); System.out.println(" Is student? " + temp.get("student"));}//end while loop }//end display

This method uses the get method inherited from the HashMap class to get and display the values in a list of JSONObject objects for a known set of keys. This is plain-vanilla Java code and shouldn't require further explanation. The results of this call to the display method are shown in the top half of Figure 1 .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
