I am not sure what I need to do in this question at all.

Question about the task

Resolved

So problem file requests to "populate the properties map with data from the file. You can read about .properties here: http://en.wikipedia.org/wiki/.properties". However, after done reading wiki page, all I know is that `.properties` is a file suffix .properties with key, value pairs, and even the key, value pairs can be various :

Several formats are possible for each line, including key=value, key = value, key:value, and key value

It seems that I need to create a FileInputStream reading console input and that input should be key-value pairs to construct .properties ? but where is this .properties from ? Totally lost. Thank you guys!

In "fillInPropertiesMap" method you should read string and this string is path to "exampleFile.properties" with properties inside so you don't have to know which file it is exactly you should just read line and this string is you file name. Properties are stored like this: key=value key=value etc.... Or you read that it may be different but key information is that properties are normally stored one pair in line. So you can easy split each line and this lines are your pairs, and next split pair to get key and value according to formats. (Sorry for my English but it's not my main language and fell free to ask more if something it's not clear) Good luck!
