Can't use variables that are declared??

[zlloyd1]

I have the following beginning of a program that I an trying to start, but stupid NetBeans won't let me use the variables I have declared for some reason. Every time I try to use one of my declared variables, it spits an error at me, and I do not see what in the world is wrong now!!

package pkginterface;
import java.awt.event.*;
import java.awt.*;
import java.util.*;
import java.io.*;
import javax.swing.*;
public class Interface implements ActionListener{

    JFrame frame = new JFrame("Interface program");
    JTextField txt1 = new JTextField(24);
    JTextArea txt2 = new JTextArea(24, 24);
    JButton b1, b2, b3; //These are all properly declared, but cannot be used without Netbeans putting red lines underneath every line in the code!!
    
           
    
        
    public static void main(String[] args) {
        // TODO code application logic here
    }

     public void actionPerformed(ActionEvent ae) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
}

For instance, if I try to do this:

package pkginterface;
import java.awt.event.*;
import java.awt.*;
import java.util.*;
import java.io.*;
import javax.swing.*;
public class Interface implements ActionListener{

    JFrame frame = new JFrame("Interface program");
    JTextField txt1 = new JTextField(24);
    JTextArea txt2 = new JTextArea(24, 24);
    JButton b1, b2, b3;
    
    b1.add // NOPE NOT ALLOWED....
           
    
        
    public static void main(String[] args) {
        // TODO code application logic here
    }

     public void actionPerformed(ActionEvent ae) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
}

I do not get this, I mean I know Java is a tough programming language to get used to , but are you telling me that it won't even let you use variables now??

You can't specify statements or expressions outside a method body.

kind regards,

Thanks for explaining this.... I did get it to work finally, by placing all of this inside of a new constructor!!
