Question

Could someone help with this please, basically I have a program with several frames in there. I have a button in frame a that when pressed open's frame b. I assumed you could do this with the following code.
class AVCustomer extends Frame implements ActionListener
     private JButton ACC;
     private Graphics g;
     public AVCustomer(AVControl avc)
          setSize(150, 350);
          setLayout(null);
          setBackground(Color.black);
          setTitle("Customer Location");
          VMachine vm = new VMachine(this);
          ACC = new JButton("ACC");
          ACC.setForeground(Color.black);
          ACC.setBackground(Color.white);
          ACC.setEnabled(true);
          ACC.setVisible(true);
          ACC.setBounds(10, 40, 100, 30);
          add(ACC);
          ACC.addActionListener(this);
          addWindowListener(new WindowAdapter() {
          public void windowClosing(WindowEvent e) {
                    dispose();
                    System.exit(0);
          setVisible(true);
          AVendingMachine vmachine = new AVendingMachine(this);
     public void actionPerformed(ActionEvent ae)
          ae.getSource();
               if(ae.getSource()==ACC)
                    vm.setVisable(true);
class VMachine extends Frame
     public VMachine(AVCustomer c)
          setSize(200, 400);
          setBackground(Color.red);
          setTitle("Vending Machine");
          addWindowListener(new WindowAdapter() {
          public void windowClosing(WindowEvent e) {
                    dispose();
                    System.exit(0);
          setVisible(false);

Answer 1

java.awt.Frame doesn't have any methods called setVisable(boolean);
