You can load the property file suing the following way:

InputStream is = new Test().getClass().getClassLoader().getResourceAsStream("app.properties");
        Properties props =  new Properties();
        props.load(is);

And then you can iterate over the map using a lambda expression like:

props.stringPropertyNames().forEach(key -> {
            System.out.println("Key is :"+key + " and Value is :"+props.getProperty(key));
        });
