swing clicking two buttons

Question

In my program there are two buttons and you have to click both of them in order for a system print out to happen. i am having trouble trying to achieve this though.

button[0].addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            button[0].setEnabled( false );
            if( button[1].isEnabled( false) );
                System.out.println("you clicked both buttons");
        }
    });
    button[1].addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            button[1].setBackground(Color.YELLOW);
            button[1].setEnabled( false );
            if( buttons[0].isEnabled( false) );
            System.out.println("you clicked both buttons");
        }
    });

I am getting errors in the line:

if( buttons[0].isEnabled( false) );

saying

The method isEnabled() in the type Component is not applicable for the arguments (boolean)

I am only a beginner in this so it would be great if someone could help or tell me another way to do this.

Answer 1

Exception is very clear. isEnabled() hasn't got parameters so you should use it in this way buttons[0].isEnabled() .

Answer 2

isEnabled does not require an argument.

Do this:

if( buttons[0].isEnabled() )

Answer 3

Here is your answer:

button1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        button1.setEnabled(false);
        if (!button1.isEnabled() && !button2.isEnabled()) {
            System.out.println("you clicked both buttons");
        }
    }
});

button2.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {

        button2.setBackground(Color.YELLOW);
        button2.setEnabled(false);
        if (!button2.isEnabled() && !button1.isEnabled()) {
            System.out.println("you clicked both buttons");
        }
    }
});
