Frlowlayout should have been FloorLayout?

Probably FlowLayout. ^^

[praveen2gupta]

Hi
Line setLayout(new Frlowlayout());
is wrong It should be written as
setLayout(new Flowlayout());
Rest is o.k.

Oh yeah, thanks.

Do not add JComponents to a JFrame directly. Get the JFrame's content pane
(see the API docs) and add your components to that pane instead.

kind regards,

class test extends JFrame implements ActionListener

JButton b1;
JTextField Tf1;
public test()
{
b1=new JButton("1");
Tf1=new JTextField(10);

setLayout(new Flowlayout());

add(b1);
add(Tf1);

addActionListen er(this);

setSize(200,200 );
setVisible(true );

}
public void actionPerformed (ActionEvent e)
if (e.getSource() == b1)
{
Tf1.setText("1" );
}
public static void main(String args[])
{
test t=new test();

See how you defined your, eg, main method; spot the diferences from your
actionPerformed method (don't mention 'static').
