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

When you are reading a file from the Jar. Please use classloader's getResource or getResoureAsstream. Find the below code snippet to read a file from Jar. The above approaches cannot read a file from jar.

    InputStream in = this.getClass().getClassLoader()
            .getResourceAsStream("com/net/resources/config.properties");

    InputStream is = Thread.currentThread().getContextClassLoader()
            .getResourceAsStream("com/net/resources/config.properties");

    URL url = this.getClass().getClassLoader()
            .getResource("com/net/resources/config.properties");
