Please provide the correct answers to the three questions above. Thank you.
Which of the following corrects defines a ButtonListener as an inner class and creates an instance of ButtonListener as a listener for the button? class ButtonListener implements ActionListener { public void actionPerformed (AnEvent event) { System.out.println("Button clicked"); } } button.addActionListener (new ButtonListener ()); class ButtonListener implements ActionEvent { public void actionPerformed (ActionListener event) { System. out.println ("Button clicked"); } } ActionListener listener = new ButtonListener (); button.addActionListener (listener); class ButtonListener implements ActionListener { public void actionPerformed (ActionEvent event) { System.out.println ("Button clicked"); } } ActionListener listener = new ButtonListener (); listener.actionPerformed (event); class ButtonListener implements ActionListener { public void actionPerformed (ActionEvent event) { System.out.println ("Button clicked"); } } button. addActionListener(new ButtonListener ()); Using the given definition of the Measurable interface: public interface Measurable { double getMeasure(); } Consider the following code snippet, assuming that BankAccount has a getBalance method and implements the Measurable interface by providing an implementation for the getMeasure method: Measurable m = new BankAccount (); System.out.println(m.getBalance ()); Which of the following statements is true? The code does not compile because a variable of type Measurable does not have a getBalance method. The code compiles but generates an exception at run time because a Measurable object reference does not have a getBalance method. The code executes, displaying the balance of the bank account. The code does not compile because you cannot assign a BankAccount object to a variable of type Measurable. Which of the following is the correct class header for a MouseclickListener class that wants to take advantage of the do-nothing methods provided by the MouseAdapter class? class MouseClickListener implements MouseAdapter class MouseClickListener extends MouseAdapter interface MouseClickListener extends MouseAdapter class MouseClick Listener implements MouseListenerStep by Step Solution
