Try this:
public static void main (String args[]); ? whats the semi colomn doing there?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Demo extends JFrame{
JLabel emptyLabel;
public Demo(){
Container c = getContentPane();
JPanel p = new JPanel();
c.add(p);
emptyLabel = new JLabel("A label");
p.add(emptyLabel);
pack();
setVisible(true);
}
public static void main (String[] args){
new Demo();
}
}
Thanks for such a swift reply however i am still facing issues. please bear with me as i have only just started this programming langauge.
As my programme is called schoolgamescompetition.java how do i incorportae the code you gave me in to it? would it look as follows?
class schoolgamescompetition
public static void main (String args[])
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Demo extends JFrame{
JLabel emptyLabel;
public Demo(){
Container c = getContentPane();
JPanel p = new JPanel();
c.add(p);
emptyLabel = new JLabel("A label");
p.add(emptyLabel);
pack();
setVisible(true);
}
public static void main (String[] args){
new Demo();
}
}
This still doesnt compile like that. I am sorry for having limited knowledge, i desperatly want to learn
thanks again
np,
try this:
[code]
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class schoolgamescompetition extends JFrame {
JLabel emptyLabel;
public schoolgamescompetition(){
Container c = getContentPane();
JPanel p = new JPanel();
c.add(p);
emptyLabel = new JLabel("A label");
p.add(emptyLabel);
pack();
setVisible(true);
}
public static void main (String[] args){
schoolgamescompetition sgc = new schoolgamescompetition();
}
}]/code]

wow, thank you very much for that, it was evry kind of you! is there a way to set the size of the frame to remain a constant?
Also i have another question (the last one so dont worry)! what i want to know is; that frame will require buttons, do you suggest that when im doing my assignment i build the structure first such as frames and buttons and then do the coding to suit?
thanks for your time
np,
I suppose that could be a way to do it.
Anyway, added a sample button so feel free to play with it :)
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class schoolgamescompetition extends JFrame implements ActionListener{
JLabel emptyLabel;
JButton someButton;
public schoolgamescompetition(){
Container c = getContentPane();
JPanel p = new JPanel();
c.add(p);
emptyLabel = new JLabel("A label");
p.add(emptyLabel);
someButton = new JButton("Click here");
someButton.addActionListener(this);
p.add(someButton);
//pack();
setSize(100,100);
setResizable(true);
setVisible(true);
}
public static void main (String[] args){
schoolgamescompetition sgc = new schoolgamescompetition();
}
public void actionPerformed(ActionEvent e){
System.out.println("what your button should do..");
}
}
