bubble sorting help

[jamiecottonuk]

Hiya i have an array of objects called messageArray which is created by converting an ArrayList to an Array

  //Converts the ArrayList MessageList to an Array of Objects
	public Object[] convertToArray() 
	{
		return messageList.toArray();
	}
	
	public void printMessageArray() 
	{
		//Creates an Array of Objects called messageArray
		Object[] messageArray = convertToArray();
 
		//Loops around the messageArray and prints out its objects
		for (int i = 0; i < messageArray.length; i++) 
		{
			String info = messageArray[i].toString();
			System.out.println (info);
		}
	}

The array has objects in it each called message and a message is made up of

 String sender, String subject, String content, int day, int month, int year, int hour, int minute

Now i want to sort the new Array which i have created by the sender by using bubble sort but not sure how can any help ?

At the moe the print out is

Jon, Tips for Travel, You should really....., Received: 24/9/2004 10:30am
Ian, Subject 2, Content 2, Received: 25/9/2004 11:30am
Bob, Subject 3, Subject 3, Received: 24/9/2004 1:30pm
Harry, Subject 4, Subject 4, Received: 24/9/2004 2:30pm

but after the sort i want

Bob, Subject 3, Subject 3, Received: 24/9/2004 1:30pm
Harry, Subject 4, Subject 4, Received: 24/9/2004 2:30pm
Ian, Subject 2, Content 2, Received: 25/9/2004 11:30am

Bubble Sort generic algorithm, which was 1 google away. Adapt to your language of choice:

0037    procedure BubbleSort( ListToSort : in out Lists) is
0038 
0039       ListIsSorted : BOOLEAN := FALSE;
0040 
0041    begin -- BubbleSort
0042       while not( ListIsSorted) loop
0043          ListIsSorted := TRUE;
0044          for ThisIndex in ListToSort'FIRST ..
0045                           Indexes'PRED( ListToSort'LAST) loop
0046              if not SortRelation( ListToSort( ThisIndex),
0047                     ListToSort( Indexes'SUCC( ThisIndex))) then
0048                 Swap( ListToSort( ThisIndex),
0049                       ListToSort( Indexes'SUCC( ThisIndex)) );
0050                 ListIsSorted := FALSE; 
0051              end if;
0052          end loop;
0053       end loop;
0054    end BubbleSort;
