Problem Description

I am working on a Java project that requires determining whether a given string represents a path to a directory or a filename. This path string can vary and might point to directories that do not currently exist on the machine. The goal is to:

1. Identify if the path string is a directory or a filename.

Examples of Path Strings

1. path="/home/{host}/project/phase1/phase2" or path``="/home/{host}/project/phase1/phase2/"
2. path="/home/{host}/project/phase1/phase2/report.txt"

Challenges

1. Distinguishing between a directory path and a filename.
2. Handling the creation of missing directories.

Tries using some predefine methods of file class in java and some logics around string handling but want a rigid solution to this problem.

I am seeking suggestions or best practices to robustly distinguish between directory paths and filenames in a path string. Additionally, I would appreciate advice on efficiently handling the creation of non-existent directories and the placement of files.

Thank you in advance for your help!
