Problem Statement

Starting with a path to some directory, determine whether the directory is empty. An empty directory contains no files nor subdirectories. With Unix or Windows systems, every directory contains an entry for “.” and almost every directory contains “..” (except for a root directory); an empty directory contains no other entries.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Empty directory step by step in the Groovy programming language

Source code in the groovy programming language

def isDirEmpty = { dirName ->
    def dir = new File(dirName)
    dir.exists() && dir.directory && (dir.list() as List).empty
}


def currentDir = new File('.')
def random = new Random()
def subDirName = "dir${random.nextInt(100000)}"
def subDir = new File(subDirName)
subDir.mkdir()
subDir.deleteOnExit()

assert ! isDirEmpty('.')
assert isDirEmpty(subDirName)
