need help to read the contents from a text file and store in a list

[Shree Chinnu]

Hi I have a problem in my code

I have to read a text file of this format

int num_thread => Total number of threads in the file

for (i = 0; i < num_thread; i++)
{
int num_message_i => Total number of messages of the next thread i
int => Total number of reference to the next thread i
for (j = 0; j < num_message_i; j++)
{
String => Author of the message
Double => Age (Posting Time) of the message
String => Title of the message
String => Contents of the message
}
}


The code I have written is as follows

public class NewThreadData {
	public static void main(String args[]) throws IOException{
		String line1;
		BufferedReader input = new BufferedReader(new FileReader("args[0]"));
		String line = input.readLine();
		StringTokenizer tokr = new StringTokenizer(line);
		Integer numDomain = Integer.parseInt(tokr.nextToken());
		int numberOfThreads = numDomain.intValue();
		System.out.println("Number of threads="+numberOfThreads);
		Vector<String> fileLine = new Vector<String>();
		Thread thread = new Thread();

		List<Thread> threadList = new ArrayList<Thread>();
		List<Message> messageList = new ArrayList<Message>();

		List<List<Message>> messageListList = new ArrayList<List<Message>>();
		List<String> str = new ArrayList<String>();

		for(int i = 0; i < numberOfThreads; i++){
			while((line1 = input.readLine())!=null){
				fileLine.add(line1);
			}
		}
		int j=0;
		Integer numMessage = null;
		Integer numReferences = null;
		Message message = new Message();
		List<Integer> numMessageList = new ArrayList<Integer>();
		int x=0;
		for(int k = 0; k< numberOfThreads; k++){
			numMessage =  Integer.parseInt((String) fileLine.elementAt(j));
			numMessageList.add(numMessage);
			thread.setNumberOfMessage(numMessage);

			x = numMessage.intValue();
			j++;

			numReferences = Integer.parseInt((String) fileLine.elementAt(j));
			thread.setNumberOfReference(numReferences);
			j++;
			for(int p = 0; p < x ; p++){
				message.setAuthorOfMessage((String)fileLine.elementAt(j));
				j++;
				message.setAgeOfMessage(Double.parseDouble((String)fileLine.elementAt(j)));
				j++;
				message.setTitleOfMessage((String)fileLine.elementAt(j));
				j++;
				message.setContentsOfMessage((String)fileLine.elementAt(j));
				j++;
				messageList.add(message);
			}
			messageListList.add(messageList);
			thread.setMessage(messageList);
			threadList.add(thread);
			messageList.clear();				
		}

But when I am trying to retrieve the data from the threadList

   
for(int i = 0; i< threadList.size(); i++){
System.out.println(threadList.get(i).getNumberOfMessage());
}

Only the Last message data is printed threadList.size() times.

Kindly let me know what might be the reason for this
