This means that wherever the codebase is used, it will run in the same manner as long as the paths are correctly adjusted. The options array may be used to indicate how symbolic links Second, using relative paths eliminates the need to hard-code paths in the program. This is because relative paths are not exposed to the public, so they are less vulnerable to malicious attacks. be used to operate on the same file as the java.io.File object.
