java - 如何获取事件单击“确定”对话框

Question

我有显示对话框

JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green.");

点击“确定”按钮时如何获取事件？

Answer 1

代码将被阻止，直到您点击

    System.out.println("before click");
    JOptionPane.showMessageDialog(null, "Eggs are not supposed to be green.");
    System.out.println("after click - do your code here");
