?Hello. I'm from Tokyo.
I'm developer of Java, recently I'm working with Server Side Java
Technology.
I read your source and my opinion is SuperClass should be
java.awt.Frame.
This code will help:
// import java.applet.Applet;
import java.awt.event.ActionListener;
import java.awt.*;
import java.awt.Window;
import java.awt.event.*;
public class clicker extends Frame implements ActionListener{
TextField text1;
Button button1;
public clicker (){
super( "This is Java Application" );
System.out.println( "---Test1---" );
text1 =new TextField(20);
button1 = new Button ("Click Here!");
button1.addActionListener(this);
add( text1 );
add ( button1 );
setLayout( new FlowLayout() );
pack();
setVisible( true );
System.out.println( "---Test2---" );
}
public static void main( String[] args ){
System.out.println( "---Test main Start!---" );
clicker Clicker = new clicker();
Clicker.show();
// Clicker.setVisible( true );
System.out.println( "---Test main End!---" );
}
public void actionPerformed(ActionEvent event){
String msg = new String ("Welcome to Java!");
System.out.println( "( event.getSource() == button1) : " + (
event.getSource() == button1) );
if( event.getSource() == button1){
text1.setText(msg);
}
}
}
Please think about one step futher what you wanted to try.
