  src is a head directory that features 2 subdirectories: gradle7 and main.
  At the main level, 'gradle7' shelters 1 folders: java.
  At level 2, in directory path 'gradle7 → java', 'java' shelters 1 subdirectories: org.
  In nested path 'gradle7 / java / org', 'org' retains 1 folders: example.
  At level 4, in directory path 'gradle7 > java > org > example', The 'example' section is devoid of content.
  Back to the top level.
  In the root directory, 'main' maintains 1 child directories: java.
  At level 2, in directory path 'main → java', 'java' hosts 1 subfolders: org.
  Within directory hierarchy 'main / java / org', 'org' groups 1 child directories: example.
  Within directory hierarchy 'main / java / org / example', The 'example' storage space is currently empty.
  Back to the top level.
