In the hierarchical display of location information using a tree structure, I would like to specify the order in which locations are shown. Is there any recommended method for doing this?

In the tree-based hierarchical display of location information, the order of locations is determined by sorting the strings registered for each hierarchy based on UTF‑8 character codes, which are used internally by Java.

If you want to arrange the locations in an arbitrary order, please add a numeric prefix to the beginning of each location name or use a similar method.

Example:
      101.Main Office\001.Sales Department
      101.Main Office\002.Planning Department
      101.Main Office\003.xxxxxx
            :
      110.Hokkaido Branch\001.Sales Department
      110.Hokkaido Branch\002.Planning Department
      110.Hokkaido Branch\003.xxxxxx
