I need help on making a button get a string from a text box!

[Shawn]

I can't seem to get my button to work right. I am just starting Java and I
am trying to get the button the retrieve the information from the text box
and put it though the if else statement. I think the problem is that the
button dosent know how to get the info from the text box. If anyone can help
if you like you can email me.

Here is the code:

// import classes

import java.awt.*;
import java.awt.event.*;
import java.applet.*;



public class Bible extends Applet implements ActionListener {

Button button1;
TextField input;
TextField output;
Label a;
Label b;
Font font1;

public void init() {

// create button
button1 = new Button( "Press this suka!" );
button1.addActionListener( this );
button1.FocusListener( input );

// create text fields
input = new TextField( 2 );
input.addActionListener( this );
output = new TextField( 50 );
output.setEditable( false );

// create labels
a = new Label( "Enter a number of 1!" );
b = new Label( "Here is your verse:" );

// add GUI components
add( a );
add( input );
add( button1 );
add( b );
add( output );

// set background color and font
font1 = new Font( "SansSerif", Font.BOLD, 17 );
setFont( font1 );
setBackground( Color.blue );

}

public void actionPerformed( ActionEvent e )
{
String var = e.getActionCommand();


// set text to nothing on run
input.setText( "" );
output.setText( "" );
showStatus( "Bible applet!" );


if ( var.charAt( 0 ) == '1' )
output.setText( "Bible Verse 1" );


else
output.setText( "Only input number 1 please!" );


}

}

What's in your field "var" at the time of the if-else? Put in
"System.out.println(var)" to find out. If you want to get info from the
text box, why not just get it from the text box: "input.getText()".

Hello Shawn,
See button.FocusListener is not there. It can be addFocusListener.
Whatever it may be. See I am giving you the code bye which you will be able
to do the things you want. O.K. Hope will help you.


import java.awt.*;
import java.applet.*;
import java.awt.event.*;
/*
<applet code="tp.class" width=640 height=480>
</applet>
*/
public class tp extends Applet implements ActionListener
{
Label label1 ;
Label label2 ;
TextField textField1 ;
TextField textField2 ;
Button button1 ;

public void init()
{
label1 = new Label("Enter a number of 1");
add(label1);

textField1 = new TextField(20);
add(textField1);


label2 = new Label("Here is your verse");
add(label2);

textField2 = new TextField(20);
textField2.setEditable(false);
add(textField2);

button1 = new Button("Press this suka !");
add(button1);
button1.setBackground(Color.lightGray);

button1.addActionListener(this);
}




public void actionPerformed(java.awt.event.ActionEvent event)
{
Object object = event.getSource();
if (object == button1)
button1_ActionPerformed(event);
}



void button1_ActionPerformed(java.awt.event.ActionEvent event)
{
String a = textField1.getText();
textField2.setText(a);
showStatus("Bible Applet !!! ");
textField1.setText("");
}
}
