Showing an Alert Dialog in Java Swing

Question

I want to giving an alert when there is an exception, like in code:

try
{
    //the code here
}
catch(Exception e)
{
    //show an alert dialog here
}

An example or a code snippet is what I need.

Answer 1

You can use JOptionPane.showMessageDialog with WARNING_MESSAGE :

JOptionPane.showMessageDialog(yourFrame,
    "WARNING.",
    "Warning",
    JOptionPane.WARNING_MESSAGE);
