Matthias Sohn 8a44216e8b Add benchmark for strategies how to move a file We can either - try moving the file and, in case the target directory doesn't exist, handle the NoSuchFileException this raises to create the target directory - or we always first test if the target directory exists and create it in case it is missing On my Mac this yields Benchmark Mode Cnt Score Error Units FileMoveBenchmark.moveFileToExistingDir avgt 5 196.490 ± 15.194 us/op FileMoveBenchmark.moveFileToExistingDirExists avgt 5 223.217 ± 54.816 us/op FileMoveBenchmark.moveFileToMissingDir avgt 5 332.169 ± 43.871 us/op FileMoveBenchmark.moveFileToMissingDirExists avgt 5 303.815 ± 137.568 us/op This means if the target directory of the move already exists the first strategy is faster by around 25 us/op otherwise the second one is faster by around 30 us/op. Which one is favorable depends on the average probability that the target directory exists in real world scenarios.
