config

I am developing a Java Desktop Application. This app needs a configuration to be started. For this, I want to supply a defaultConfig.properties or defaultConfig.xml file with the application so that If user doesn't select any configuration, then the application will start with the help of defaultConfig file.

But I am afraid of my application crash if the user accidentally edit the defaultConfig file. So Is there any mechanism through which I can check before the start of the application that whether the config file has changed or not.

How other applications (out in the market) deal with this type of situation in which their application depends on a configuration file?

If the user edited the config file accidentally or intentionally, then the application won't run in future unless he re-installs the application.
