I am getting the below error while running the java files using the mobility dataset

at org.fog.mobilitydata.DataParser.parseResourceData(DataParser.java:99) at org.fog.placement.LocationHandler.parseResourceInfo(LocationHandler.java:150) at org.fog.test.perfeval.CardiovascularHealthMonitoringApplication.createFogDevices(CardiovascularHealthMonitoringApplication.java:162) at org.fog.test.perfeval.CardiovascularHealthMonitoringApplication.main(CardiovascularHealthMonitoringApplication.java:109)

Same here.

@mehbub160 Figured out that in my case the problem had to do with the missing File.separator. It appears that by default the path separator is "//", so I changed it to (for example in DataParser.parseResourseData()):

BufferedReader csvReader = new BufferedReader(new FileReader(String.format(".%sdataset%sedgeResources-melbCBD.csv", File.separator, File.separator)));

Had to change in References.java and the other files too.

Dunno if necessary but I was thinking on creating a PR to solve it.
