When to use “getResourceAsStream” method?

Question

I was confused using the said method because while loading some properties file people are following a different approaches...

Properties prop 
 = new Proper         


        

Answer 1

getResourceAsStream searchs you classpath for the given file/resource and it can also provide InputStreams of resources from inside a JAR.

So, if your properties exist in some folder in the physical filesystem (e.g. user folder, ...) use FileInputStream and if the file is embedded in your classpath (e.g. as a resource inside the JAR) use getResourceAsStream.
