title: Java property file with different extension
body: <p>I know its a bad question, but just wanted to know. We have property files (.properties) in java, where we can read and write using Java.util.Properties class. I am able to use the same Java.util.Properties class to read and write file with different extension like .dat , .ini which has key-value pair. Do we have any potential difference when .dat or .ini file is read using Java.util.Properties when compared to having file as .properties. </p>
