  Bug in TeXtField constructors
 
public TextField (int columns)
public TextField (String text, int columns)


The above constructor's creates a TextField with text as
its content and a width of columns.Some constructors
permit you to set the width of the TextField on the screen,
but the current LayoutManager may change it.
if u give negative value in the columns Textfield constructor
accepts and produce its default size.

Alternate solutions
produce some negative exception for it.

//Example for TextField
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class TestText extends Applet implements ActionListener
{

TextField name;
TextField no;
TextField age;

public void init()
{
setLayout(new FlowLayout(FlowLayout.CENTER));
name = new TextField("Bye", -6);//negative value of column's width
no = new TextField(-10);
age = new TextField(-90);
add(name);
add(no);
add(age);
name.addActionListener(this);
no.addActionListener(this);
age.addActionListener(this);
}

public void actionPerformed(ActionEvent ae)
{
repaint();
}

public void paint(Graphics g)
{
g.drawString(name.getText(),20,20);
g.drawString(no.getText(),20,40);
g.drawString(age.getText(),20,60);
}
}
