Java Continuing code after JOptionPane

So, I'm trying to make a popup message appear when something happens, but I want the code to continue as soon as the message appears, and not wait for the user to press the okay button.

JOptionPane.showMessageDialog(null, message, "Alert!", JOptionPane.ERROR_MESSAGE);
System.out.println("HI!");

When I do this, it doesn't print HI! until I press okay. How can I fix this?

Solution

  • You can create separate thread and invoke JOptionPane.showMessageDialog from it:

    new Thread(new Runnable(){
    public void run() {
        JOptionPane.showMessageDialog(null, "message", "Alert!",
                JOptionPane.ERROR_MESSAGE);
    }
}).start();

System.out.println("HI!");
