Retrieve all data on textArea question ---please help

Question

hi, I am writing a program that will retrieve all data from Access to JTextArea. For example, DB has 10 records and I would like to show all 10 records at once on JTextArea. However, in my code, i can retrieve the last records only. The following is part of my code, please help me to clear my thought. I think i got the idea about loop but dunno how to do. thanks.
//the data access class about sql query
public static String retrieve() throws SQLException
String query = "SELECT ClockIn, ClockOut FROM TimeCard";
Statement statement = connection.createStatement();
ResultSet r = statement.executeQuery(query);
String t3 = null;
while(r.next())
String t1 = r.getString(1);
String t2 = r.getString(2);
t3 = t1 + " " + t2 + "\n";
statement.close();
return t3;
//the JTextArea class
public void performUserDisplay()
testTime tTime = new testTime();
try
testTime.connect();
message.setText(tTime.retrieve()); //*** i think here has the problem too but i have no idea what to do
testTime.disconnect();
catch(Exception e)
System.out.println("Exception");
I know maybe i should use message.append() but still, I am sort of new to java, so i don't really know how to do it.
Please help me and thanks in advance

Change
String t3 = null;
while(r.next())
String t1 = r.getString(1);
String t2 = r.getString(2);
t3 = t1 + " " + t2 + "\n";
statement.close();
return t3;
...to
StringBuffer res = new StringBuffer();
while(r.next())
    res.append(r.getString(1)).append(" ").append(r.getString(2)).append("\n");
statement.close();
return res.toString();
