Thread: Help in netbeans

Can you make a small, complete program that compiles, executes and shows the problem? It should have the minimum code needed to show the problem.

this is a small code i made, this is where i put a combobox with brands to select:

public class prueba2 extends javax.swing.JFrame {
 
 
    public prueba2() {
        initComponents();
    }
 
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {
 
        select = new javax.swing.JComboBox();
        jLabel1 = new javax.swing.JLabel();
 
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        getContentPane().setLayout(null);
 
        select.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "Select", "Sony", "Samsung", "Acer" }));
        getContentPane().add(select);
        select.setBounds(87, 67, 94, 20);
 
        jLabel1.setText("Select your brand");
        getContentPane().add(jLabel1);
        jLabel1.setBounds(80, 30, 110, 20);
 
        pack();
    }// </editor-fold>                        
 
    public static void main(String args[]) {
 
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new prueba2().setVisible(true);
            }
        });
    }
 
    // Variables declaration - do not modify                     
    private javax.swing.JLabel jLabel1;
    private javax.swing.JComboBox select;
    // End of variables declaration                   
}
 
and this is the second jframe, where i want to put what i've selected before in a textfield
 
 
public class prueba1 extends javax.swing.JFrame {
 
    public prueba1() {
        initComponents();
    }
 
 
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {
 
        receive1 = new javax.swing.JTextField();
 
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        getContentPane().setLayout(null);
        getContentPane().add(receive1);
        receive1.setBounds(103, 87, 146, 31);
 
        pack();
    }// </editor-fold>                        
 
    /**
     * @param args the command line arguments
     */
    public static void main(String args[]) {
 
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new prueba1().setVisible(true);
            }
        });
    }
 
    // Variables declaration - do not modify                     
    private javax.swing.JTextField receive1;
    // End of variables declaration                   
}

and i don't know how to make it

You have posted two separate, independent classes which would be executed as separate programs.
Where is there supposed to be any connection between these two classes?

One confusing part is that both classes have main() methods indicating that they are intended to be executed as the MAIN program. One of the classes must be subordinate to the other. One class is the main class that starts the execution for the program. That class will then create an instance of the second program as needed using the new statement. When that instance is created in the first class, the reference to the instance of the second class should be saved so that the two classes are connected so that methods in the first class can call methods in the second class. For example to pass the selected item from the combobox to go in the textfield.

Sorry, I don't know anything about netbeans's projects.

One of the classes needs to have a main() method where the program's execution starts. The code in that class can create instances of all the other classes that are needed for the program to do what its going to do.
For example a method in preuba2 has this statement that creates an instance of a combo box:
select = new javax.swing.JComboBox();
