// explanation

path1.resolve("log") appends the relative segment to yield /app/./sys/log, and path2.resolve("/readme/") replaces the path with the absolute /readme/ because an absolute argument to resolve() overrides the base path; the printed pair is therefore /app/./sys/log and /readme (assuming res2 was meant to hold the second resolve result).
