Question

i have some code that i am trying to recompile and understand, but i have a method that does not compile and i wish to find the good work around. the method is as follows.

private void launchEventPanel(String title) { 
    EventQueue.invokeLater(new Runnable(title) { 
        public void run() { 
        JFrame myFrame = new JFrame(); 
        myFrame.setTitle("Conference Call"); 
        myFrame.setIconImage(CallConference.this.myCore.myPanel.myIconManager.getPromptIcon(CallEMart.class.toString())); 
        myFrame.getContentPane().add(CallConference.this.myEventPanel, "Center"); 
        myFrame.pack(); 
        myFrame.setVisible(true); } }); }

the second line of the EventQueue.invokeLater does not compile, i get the error “Anonymous class implements interface, cannot have arguments”.

any help and work around is highly appreciated. thanks!

Well, as the message says: java.lang.Runnable is an interface so you cannot pass title to its constructor.
Use:

EventQueue.invokeLater(new Runnable() { 

instead.

Note that title isn’t used anywhere. If you need it inside the Runnable, you need to declare it final:

private void launchEventPanel(final String title) { 
EventQueue.invokeLater(new Runnable() { 
    public void run() { 
    JFrame myFrame = new JFrame(); 
    myFrame.setTitle(title);
