Enumerate all files in the data folder of Processing

herunterladen

There are lots of ways to enumerate all the files inside the data folder of Processing sketch. Here are 2 of them. The first one uses the Java DirectoryStream class wie geht musik downloaden. The second one uses the static function walkFileTree from the Files class wie kann ich ein video aus zdf mediathek herunterladen.
 
Example with DirectoryStream

try {
    DirectoryStream<Path> stream = Files.newDirectoryStream(Paths.get(dataPath(""))); 
    for (Path file : stream) {
      println(file.getFileName());
    }
  } 
  catch (IOException e) {
    e.printStackTrace();
}

Example with Files.walkFileTree

try {
    Files.walkFileTree(Paths.get(dataPath("")), new SimpleFileVisitor<Path>() {
      @Override
        public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
        println(file.getFileName());
        return FileVisitResult.CONTINUE;
      }
    }
    );
  } 
  catch (IOException e) {
    e.printStackTrace();
}

 

Looping through a List in Processing

where can I download herr der ringe schlacht um Mittelerde

Here is a piece of demonstration code to use various ways to loop through a List or ArrayList in Processing, i.e e-mail for free. Java. The first two examples use for loop and the third one uses the while loop.
 
We initialize the ArrayList with random integers.

ArrayList<Integer> iList = new ArrayList<Integer>();
iList.add(floor(random(10)));
iList.add(floor(random(10)));
iList.add(floor(random(10)));

The first method is the traditional way to loop with an index game driver for free.

for (int i=0; i<iList.size(); i++) {
    println(iList.get(i));
}

The second method also uses the for loop, but with alternate syntax.

for (int i : iList) {
    println(i);
}

The third method uses the Iterator through the ArrayList herunterladen.

Iterator<Integer> it = iList.iterator();
while (it.hasNext()) {
    int i = it.next();
    println(i);
}
