printing on an applet

[Raj]

we use system.out.println to print on the screen what stmt do we use if we want to print a value of an variable on an applet

[Ulf Dittmer]

The same. Check the Java Console for System.out output of applets.

[Raj]

how do i do that

[Ulf Dittmer]

That depends on the operating system you're using. Windows has a little Java icon in the tray which will open the Console. You can also open it from the Java Plugin control panel. On OS X, this output goes to Console.log.

well i have a database in ms access and i am storing the entries of the database in an array data now i have to print the conents of this araay on the frame of an applet. how do i do that?

private void RetrieveData ()
{
try
{
                        

ResultSet rs = st.executeQuery("Select * from MediInfo");
 

ResultSetMetaData md = rs.getMetaData();

                        int colcount = md.getColumnCount();
                        
Object[] data = new Object[colcount];

                        
while (rs.next())
{
for (int i=1; i<=colcount; i++)
{

                                      data[i-1] = rs.getString(i);
                                    System.out.println(data[i-1]);
                                               //printing on the cosole
}

}
}
catch(Exception e) {System.out.println(e);}

Wouldn't it make more sense to add those messages as text in a TextArea? It's much easier to accomplish, plus AWT takes care of wrapping the text, scrolling, etc.

[Raj]

i did make a text area but how do i pass the contents of data[] on to the text area.

[Ulf Dittmer]

By iterating through the array and calling the TextAreas appendText (or something similar) method for each item.
