Slow Applet

Question

this has got to be one of the simplest applets, yet it takes over 10 minutes to run the second part.
here's the source
(done in netbeans, I'm a newb)
import java.awt.*;
import java.awt.event.*;
import java.applet.Applet;
public class gpaApplet extends java.applet.Applet implements ActionListener {
  public Button sub=new Button("Submit");
  public TextField number=new TextField(5);
public void init() {
setLayout(new FlowLayout());
add(number);
add(sub);
sub.addActionListener(this);
public void actionPerformed(java.awt.event.ActionEvent a) {
if (a.getSource()==sub) {
int num=3, index=0;
TextField[] ta = new TextField[num];
remove(number);
remove(sub);
setLayout(new FlowLayout());
add(ta[0]);
}this is not all of what i plan to do with it, but i need this to work in order to do what i plan to do. after it removes the textfield and the button (number and sub), it takes 10 minutes+ (i never waited to see how long it takes, all i know is that its still trying after the 10 minutes but still hasnt displayed anything to the screen) to display just 1 textfield from the array.
when i dont use arrays, and i just make 1 textfield and display it (after removing the textfield and button) it takes about 2 -3 minutes to display the textfield,
i've tried it on 3 computers, one of which was a 3 ghz machine with 1 gig of ram. so i dont see why its soooo daam slow
can someone please help me solve this problem?

Answer 1

ok, now the problem arises here. i need to make the "num" number of textfields, based on whatever is input (i'll add that code later, after i get this to work).
so how do i make as many textfields as i want? i tried putting a "for" loop within...
TextField[] ta = new TextField[] {
//for loop goes here
}i tried putting that loop in there, but it would not allow it. gave some kind of error.
so my question. how do i make as many textfields as i want, based on the number that the user enters.
