Guys,

I have a problem with explanation. If problems in this snippet was corrected it would be E.

So:


It prints:


/user/.././root/../kodiacbear.txt
/kodiacbear.txt
../lion



And i have a problem with understanding what exactly relativize method does. Why last line prints

../lion

when file kodiacbear.txt is in system root? What am i missing?

I presume you know what an absolute path and a relative path mean. Have you read the documentation for Path#relativize(Path)? It isn't crystal clear, but it means how you would get from the end of this path to the target of the path passed as an argument. If you start from the location of the kodiacbear.txt file, and lion is in the same directory, ./lion will find the lion file.

I would understand if the answer was ./lion (like you wrote) or /lion (like i thought)

But i am asking - why it's ../lion (double dots)
 
It is sorta covered in the JavaRanch Style Guide.
