hello guys i have this code:

                  if (listOfFiles[i].isFile()) {
                      if(!listOfFiles[i].isHidden()) {
                           files = listOfFiles[i].getName();
                           List=List+files+"?:";
                      }                                              
                  }
                  else if(listOfFiles[i].isDirectory()) {
                        File Test = new File(listOfFiles[i]+"\\");
                        File [] Rec= Test.listFiles();
                        if(Rec!=null) 
                            if(!listOfFiles[i].isHidden()) {
                                files=listOfFiles[i].getName();
                                List=List+files+"*:";
                            }
                        }
          }

this code in windows return the real directory and all file in folder' but on mac and linux i see only the files.. why?

Answer 1

You need to replace "\\\\" with File.separator .

File Test = new File(listOfFiles[i]+File.separator);

This will then work in a cross-platform way: it'll use \\ on Windows, but / on Mac and Linux.

One note of caution: there's also a File.pathSeparator , and that has a tempting name for what you're doing, but it's not the right thing. It's used for separating lists of paths, and it's ; on Windows and : on Mac and Linux.

By the way, it's really not considered a good idea to have instance variables that start with a capital letter (like Test above). Class names should be capitalized, but not method names or field names.
