Re: Applet problem !!!

I figure out something but new problem arises...
I?ll post you 2 almost identical codes:
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
public class Square extends Applet implements ActionListener {
Label label;
TextField number;
int num;
public void init()
{
label = new Label( "Enter an integer:" );
number = new TextField( "0", 10 );
number.addActionListener( this );
add( label );
add( number );
}
public void paint ( Graphics g )
{
squareOfAsterisks( g );
}
public void squareOfAsterisks ( Graphics h )
{
int xpos, ypos=50;
for ( int i = 1; i <= num; i++ ) {
xpos = 50;
for ( int j = 1; j <= num; j++ ) {
h.drawString( "*", xpos, ypos );
xpos += 15;
}
ypos += 15;
}
}
public void actionPerformed( ActionEvent e )
{
num = Integer.parseInt( number.getText() );
repaint();
}
}
AND
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Square extends JApplet implements ActionListener {
JLabel label;
JTextField number;
int num;
public void init()
{
Container c=getContentPane();
c.setLayout(new FlowLayout());
label = new JLabel( "Enter an integer:" );
number = new JTextField( "0", 10 );
number.addActionListener( this );
c.add( label );
c.add( number );
}
public void paint ( Graphics g )
{
squareOfAsterisks( g );
}
public void squareOfAsterisks ( Graphics h )
{
int xpos, ypos=50;
for ( int i = 1; i <= num; i++ ) {
xpos = 50;
for ( int j = 1; j <= num; j++ ) {
h.drawString( "*", xpos, ypos );
xpos += 15;
}
ypos += 15;
}
}
public void actionPerformed( ActionEvent e )
{
num = Integer.parseInt( number.getText() );
repaint();
}
}
Now, my question is: Why does the first one work while the second one doesn?t when these two are almost the same?
