What is property change value of JOptionPane and When it changes?

I see that when creating a customized dialog with JOptionPane, in the method propertyChange that handle property change events, people often check whether the current property value equals a certain value, say VALUE_PROPERTY. And after that they would check which button in the dialog the user choose.

So what is the property value?

Specifically, what is the meaning of VALUE_PROPERTY and INPUT_VALUE_PROPERTY?

What does a user do to change the property value?

It is not that complicated. The show dialog method returns an integer. With this value you are able to understand what the user selected:

For instance, 

YES_OPTION, means that the user clicked yes.

So, how is this translated to the logic?

If you were implementing a listener, you would do something like this:

if(the user selected yes)
    //do something
