Scan directory and print folders' name

leota · March 2015

Hi there, as title says I want to scan a directory and print the folders' name found there. I'm able to do that with the following code but I want the program to print out just the folders' name in that directory, not the whole path. Here's the code:

import java.io.File;

File dir; 
File [] files;

void setup() {
  dir= new java.io.File(dataPath(""));
  files= dir.listFiles();
}

void draw() { 
  noLoop();
  for (int i = 0; i <= files.length - 1; i++)
  {
    String path = files[i].getAbsolutePath();
    println(path);
  }
}

My output is something like: /Users/MyUser/Documents/...../FOLDER_NAME but I would like to print only FOLDER_NAME. How do I do that?

thanks in advance

import java.io.FileFilter;

final FileFilter FOLDER_FILTER = new FileFilter() {
  boolean accept(File f) {
    return f.isDirectory();
  }
};

File folder = dataFile("");
File[] dirs = folder.listFiles(FOLDER_FILTER);

println(folder);
println();

printArray(dirs);
println();

String[] dirNames = new String[dirs.length];
for (int i = 0; i != dirs.length; dirNames[i] = dirs[i++].getName());
printArray(dirNames);

exit();
